What has been written in these blogs are straight from the horses mouth, that is a real person, having a real problem and solving it with a real solution. Where else would you find these tips for OBIEE, no where but here. Check them out if you are into the Oracle Business Intelligence world.

And now let’s start the countdown.

Tip 10: Halt background services to improve performance.

This tip is one of our favorites because it always works. Running in the background of Windows are scores of services, small processes used by Windows and many Windows applications. The thing is, you don’t need all these services — especially for applications you never use — and many of them actually slow your PC down.

Win XP power users have long known that you can easily eke a little extra performance out of your PC by disabling services that are completely unnecessary or that don’t need to be running all the time. Here’s how it works.

1. Click Start > Run, type services.msc and click OK. This will bring up the Services management console. Click on the Extended tab at the bottom of this window; each background service running on your PC is listed here. Windows includes a fairly detailed description of each service; simply drag the Description column wider to read more of each description, or click on a service to see its full description in the left pane.

2. Double-click a service to bring up a window with several options. In the Startup Type area, you can set the service to run automatically in the background at all times so it’s ready whenever it’s needed, or you can tell it to run manually, which means you’ll have to go into this Services management console and re-enable it if an application needs it.

You can also completely disable the service. In general, you want to disable services tied to applications and/or features you don’t use or rarely use. You can find a great list of appropriate services to disable at the Elder Geek’s Services Guide For Windows XP.

If you’re logged onto the computer as the administrator, you can also pause the service (click the Pause button in the Service Status area just below the Startup Type area), then see how the computer behaves. Danger signs include crashes or other erratic behaviors in your applications, such as running slowly or getting stuck on a query prompt. Click Resume to start up the service again.

Tip 9: Increase available disk space by scaling back System Restore.

It’s not perfect, but Windows System Restore is a useful first step in recovering your PC or drive from a major system error. However, it can consume more than 10 percent of your total hard drive space.

If you find yourself desperate for an extra few gigabytes — particularly on secondary storage drives — there’s an easy way to reclaim data space by simply limiting the number of System Restore points Windows XP establishes. This one’s a snap and there’s no tangible increase of risk, which is why we love it.

1. Right-click on My Computer and select Properties > System Restore.

2. If you have just one hard drive, skip to step 3. Otherwise, select the drive on which you want to gain storage space and click the Settings button.

3. Adjust the slider to the left to use less disk space, and Win XP will reduce the number of System Restore points by the appropriate amount.

Tip 8: Scrub your hard drive clean.

Windows Support Tools, provided free by Microsoft, are a suite of some 20+ separate applications that are extremely handy for a number of uses. Ordinary PC users probably won’t use many of these apps — they’re mostly used by IT pros to troubleshoot and analyze Windows XP. But even if you’re not an expert, don’t be afraid of using the Windows Installer Clean Up Utility, which will help you remove all leftover files from a failed uninstall of a Windows Installer application.

Download Windows Support Tools from Microsoft’s Download Center. (If you’re curious about the other apps in the suite, check out the help file included in the Windows Support Tools Program group.)

To run the Windows Installer Clean Up Utility, go to the command prompt (select Start > Run) and type msicuu.exe. You’ll see a list of all applications with uninstall data. Select the ones you want to get rid of and click the Remove button. Obviously, you want to use caution here — don’t clear the install data for an application unless you’re absolutely sure you won’t ever need it.

Tip 7: Run two displays on the same PC.

This tip is for the worker bee. Adding a second display to your PC won’t quite double your productivity, but it will make your computing life easier. Walk around a cube farm these days, and you’ll likely see at least a few power users doubling up.

Thankfully, Windows XP makes it extremely easy.

1. Plug the second display into your computer. (Many video cards today have a second Video Out port; if not, you’ll have to install a second video card.)

2. Right-click on your desktop and click Properties to bring up the Display Properties window. Click on the Settings tab.

3. See the grayed-out box to the right of the black box? That’s your second monitor. Click on it and then click the check box next to “Extend my Windows desktop onto this monitor” to enable it. From here you can adjust the resolution of the secondary display. The goal here is to have a desktop that spans both of your displays, so if your second screen is physically located to the left of your primary one, drag and drop the #2 monitor to the left of the #1 display.

Tip 6: Force unresponsive applications to close at shutdown.

When it comes to balky PCs, few things annoy us more than the moment when we try to shut down Windows and it tells us it can’t because some crashed application isn’t responding, and that we have to do it ourselves by clicking the End Now button.

This registry hack changes that. Here’s how it works.

1. Launch RegEdit (select Start > Run, type regedit and click OK) and browse to HKEY_USERS\.DEFAULT\Control Panel\Desktop

2. Find the string called AutoEndTasks. Right-click it, select Modify from the pop-up menu, and change the data value from 0 to 1. (If you can’t find this string, create it by selecting Edit > New > String Value and set the data value to 1.)

3. Close RegEdit and reboot.

Tip 5: Automatically optimize your hard drive.

One of the keys to system performance is an optimized hard drive. Typically, you optimize your hard drive using Windows’ Defrag utility. But there’s a great registry hack that will force Win XP to automatically optimize the location of files when your PC is idle. Here’s how it works.

1. Open RegEdit and browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
OptimalLayout

2. Find the string called EnableAutoLayout, and change its data value to 1. (If this string doesn’t exist, create it and set the value to 1.)

3. Exit RegEdit and reboot your PC. Done!

Tip 4: Set a custom resolution.

Notice a trend in the second half of this story? If you answered, “They’re all registry hacks,” you are correct. Windows XP’s registry loads an amazing amount of flexibility and customization in a fairly low-risk package.

Tip number 4 on our list is another one of our favorite registry hacks. Windows XP allows you to specify a large number of set screen resolutions based on what types of images your display can accept. However, in a few rare instances, you may want to specify a non-standard resolution for a clearer or more accurate picture. This tip allows you to do just that. It’s one of those tips that doesn’t seem all that handy — until you desperately need it. Plus, it’s just plain cool. If you have a wonky projector or TV screen you want to use with a laptop or PC, you might want to give this a try.

Here’s how it works:

1. Open RegEdit and browse to HKEY_CURRENT_CONFIG\System\CurrentControlSet\Control\VIDEO\
{the address of your primary video card…it often begins with “23A77BF7″}\0000\

2. The Default Settings.XResolution data value is the horizontal resolution, and the Default Settings.YResolution data value is the vertical. Double-click the Default Settings.XResolution data entry, select the Decimal radio button, and in the Value Data field, enter your desired horizontal resolution. Then do the same with Default Settings.YResolution to change the vertical resolution.

3. Exit RegEdit and reboot your PC.

If you’re scared of tweaking your registry on this one, a handy app called PowerStrip ($29.95, available for a free try-before-you-buy download), allows you similar resolution-changing functionality.

Tip 3: Stay on top of registry changes.

Given the power and flexibility of Windows XP’s registry (and the large number of registry hacks in this Top 10), it’s no surprise that the number 3 XP tip involves keeping track of any and all changes made to your registry.

But given the prevalence of spyware, rootkits, and other malware these days, knowing what you’ve done to your registry is a secondary concern to knowing what other applications are doing to it.

For peace of mind — and occasionally, for curiosity’s sake — we consider SysInternal’s Regmon an essential piece of our OS. It’s a freeware application that allows you to browse through all the keys in the registry, filtering in a variety of ways to pinpoint specific registry changes.

For example, you can quickly filter for certain applications. If you’re having trouble with Windows Media Player, you click on the Options menu, then Filter. At the menu, type wmplayer into the Include field. When you see the resulting list, you can double-click any entry to open up its registry value.

Because you can search and filter, Regmon is also an excellent method for tracking down hard-to-find registry items.

Tip 2: Recover lost data.

Everyone has accidentally deleted files from their hard drive, and very few feelings are as low as the moment right after you nuke 300 irreplaceable photographs of your kids/dogs/life. Actually, one feeling is worse than that: accidentally quick-formatting your entire drive.

Even if you regularly back up your drives, mistakes happen. That’s why this tip is paramount. It’s also really simple. There’s an excellent downloadable data recovery app for XP called Zero Assumption Recovery that can help. Don’t waste another minute — download and install it now.

When you run into trouble, here’s what to do:

1. The moment you delete your data, stop using your hard drive. Don’t save or install any new applications — they’ll be written over your recently departed data.

2. Run Zero Assumption Recovery. You already had it installed, right?

3. Select the hard drive you want to scan. Wait for the scan to finish. (This can take between one and two hours — part of Zero Assumption Recovery’s effectiveness is its thoroughness.)

4. With any luck, you’ll see a list of your missing folders and files. The freeware version of Zero Assumption Recovery allows you to recover up to four folders per scan. If you pay $100 for the full version, you get full recovery.

Note: You can also use Zero Assumption Recovery to recover deleted photos from your camera’s memory card.

Tip 1: Automatically log when and why shutdowns have occurred.

Love it or hate it, Windows XP is undeniably more stable than its predecessors. But it still crashes, and it still has occasional trouble shutting down. This registry hack logs all shutdown errors, telling you when, where, and why strange and annoying things have happened.

Some folks have the luxury of packing their buggy PC off to a help desk. But if you like to get your hands dirty, consider this essential tweakage.

Here’s how to set up logging for unexpected system shutdowns:

1. Open RegEdit and browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
Reliability

2. Set the ShutDownReasonUI data value to 1. (If this string doesn’t exist, create it and set the value to 1.)

3. Exit RegEdit and reboot your PC.

To examine the log you’ve created, open up the Event Viewer, which you’ll find by selecting Control Panel > Administrative Tools > Event Viewer. Click on the System subheading and you’ll see a massive list of system events. Errors will be marked with a red X or a yellow exclamation mark. Double-click on the error and you’ll see details that may help you unravel the mystery.

Downloading email attachments is another way adware can arrive, they use this method the same way virus writers used it so often in the past, although this method is rather remote today compared to other methods.

Firewalls – By default, if you already have a router as mentioned above, then you already have a firewall too. Software firewalls (software that you install on your pc to keep intruders out) can be found all over the internet, but a hardware router is one of the best firewalls you can get. If you have a router, then by default you also have a firewall already. More detailed information on these is listed in the link below.

Wireless connections must be made secure, if you are using a wireless router as most are, make sure you have done a few simple steps to keep your information from being stolen out of the airwaves. You can password protect your router by setting up encryption. This should be done by everyone who is using a wireless router. Thats why you can see your neighbors computer, its because they haven’t bothered to set this up. If password encryption is setup, your neighbors will not be able to see your computer or access it. You can also setup remote access by only allowing only specific computers to access your router. This means you tell the router which computers can access your connection, anyone else (or any new laptop, etc.) would not be able to access it unless you say so. If you have done either of these methods, then you have a secure system (at least far more secure then most would do!).

Some spyware/adware/malware arrive as a hidden “add on” when you install free software “gimmies”. Remember that free software (called freeware, freeware is different from shareware, as shareware usually costs money after a free trial period ends and includes full support, while freeware is always free and normally has no support or limited support). Normally freeware is free for a reason. Most companies will not spend all their time supporting and writing something to give away free, unless they have a way to get some money in return (can’t blame them, it makes business sense), so they get paid to embed hidden programs in with your freeware. These programs (called spyware or adware) track you, display ads to you, create pop up windows, or use your machine resources, among other things. The best thing you can do is become familiar with programs that run in your task list, and become familiar with programs that run when you reboot your computer, as all spyware/adware/malware need a way to reactive in case you shutdown. This will always lead you to the source of your popup windows, or advertising popups that are being caused from adware or spyware. You may also want to use a program like Disk and Registry Alert, which allows you to track changes to your drive or registry. Note also if you want to know what all those tasks are showing in your ctrl-alt-del task list, view the computer task list directory here.

Because Windows XP has to be all things to all people it has many services running that take up system resources that you will never need. Below is a list of services that can be disabled on most machines:

• Alerter
• Clipbook
• Computer Browser
• Distributed Link Tracking Client
• Fast User Switching
• Help and Support – (If you use Windows Help and Support leave this enabled)
• Human Interface Access Devices
• Indexing Service
• IPSEC Services
• Messenger
• Netmeeting Remote Desktop Sharing (disabled for extra security)
• Portable Media Serial Number
• Remote Desktop Help Session Manager (disabled for extra security)
• Remote Procedure Call Locator
• Remote Registry (disabled for extra security)
• Remote Registry Service
• Secondary Logon
• Routing & Remote Access (disabled for extra security)
• Server
• SSDP Discovery Service – (Unplug n’ Pray will disable this)
• Telnet
• TCP/IP NetBIOS Helper
• Upload Manager
• Universal Plug and Play Device Host
• Windows Time
• Wireless Zero Configuration (Do not disable if you use a wireless network)
• Workstation

To disable these services:

1. Go to Start and then Run and type “services.msc”
2. Doubleclick on the service you want to change
3. Change the startup type to ‘Disable”

2. Turn Off System Restore

System Restore can be a useful if your computer is having problems, however storing all the restore points can literally take up Gigabytes of space on your hard drive. To turn off System Restore:

1. Open Control Panel
2. Click on Performance and Maintenance
3. Click on System
4. Click on the System Restore tab
5. Tick ‘Turn off System Restore on All Drives’
6. Click ‘Ok’

3. Defragment Your Pagefile

Keeping your pagefile defragmented can provide a major performance boost. One of the best ways of doing this is to creat a separate partition on your hard drive just for your page file, so that it doesn’t get impacted by normal disk usage. Another way of keeping your pagefile defragmented is to run PageDefrag. This cool little app can be used to defrag your pagefile, and can also be set to defrag the pagefile everytime your PC starts. To install:

1. Download and Run PageDefrag
2. Tick “Defrag at next Reboot”,
3. Click “Ok”
4. Reboot

4. Speedup Folder Access – Disable Last Access Update

If you have a lot of folders and subdirectories on your computer, when you access a directory XP wastes a lot of time updating the time stamp showing the last access time for that directory and for ALL sub directories. To stop XP doing this you need to edit the registry. If you are uncomfortable doing this then please do not attempt.

1. Go to Start and then Run and type “regedit”
2. Click through the file system until you get to “HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\FileSystem”
3. Right-click in a blank area of the window on the right and select ‘DWORD Value’
4. Create a new DWORD Value called ‘NtfsDisableLastAccessUpdate’
5. Then Right click on the new value and select ‘Modify’
6. Change the Value Data to ‘1′
7. Click ‘OK’

5.Disable System Sounds

Surprisingly, the beeps that your computer makes for various system sounds can slow it down, particularly at startup and shut-down. To fix this turn off the system sounds:

1. Open Control Panel
2. Click Sounds and Audio Devices
3. Check Place volume icon in taskbar
4. Click Sounds Tab
5. Choose “No Sounds” for the Sound Scheme
6. Click “No”
7. Click “Apply”
8. Click “OK”

6. Improve Boot Times

A great new feature in Microsoft Windows XP is the ability to do a boot defragment. This places all boot files next to each other on the disk to allow for faster booting. By default this option in enables but on some builds it is not so below is how to turn it on.

1. Go to Start Menu and Click Run
2. Type in “Regedit” then click ok
3. Find “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOpt imizeFunction”
4. Select “Enable” from the list on the right
5. Right on it and select “Modify”
6. Change the value to “Y to enable”
7. Reboot

7. Improve Swapfile Performance

If you have more than 256MB of RAM this tweak will considerably improve your performance. It basically makes sure that your PC uses every last drop of memory (faster than swap file) before it starts using the swap file.

1. Go to Start then Run
2. Type “msconfig.exe” then ok
3. Click on the System.ini tab
4. Expand the 386enh tab by clicking on the plus sign
5. Click on new then in the blank box type”ConservativeSwapfileUsage=1″
6. Click OK
7. Restart PC

8. Make Your Menus Load Faster

This is one of my favourite tweaks as it makes a huge difference to how fast your machine will ‘feel’. What this tweak does is remove the slight delay between clicking on a menu and XP displaying the menu.

1. Go to Start then Run
2. Type ‘Regedit’ then click ‘Ok’
3. Find “HKEY_CURRENT_USER\Control Panel\Desktop\”
4. Select “MenuShowDelay”
5. Right click and select “Modify’
6. Reduce the number to around “100″

This is the delay time before a menu is opened. You can set it to “0″ but it can make windows really hard to use as menus will open if you just look at them – well move your mouse over them anyway. I tend to go for anywhere between 50-150 depending on my mood

9. Make Programs Load FasterThis little tweak tends to work for most programs. If your program doesn’t load properly just undo the change. For any program:

1. Right-click on the icon/shortcut you use to launch the program
2. Select properties
3. In the ‘target’ box, add ‘ /prefetch:1′ at the end of the line.
4. Click “Ok”

Voila – your programs will now load faster.

10. Improve XP Shutdown Speed

This tweak reduces the time XP waits before automatically closing any running programs when you give it the command to shutdown.

1. Go to Start then select Run
2. Type ‘Regedit’ and click ok
3. Find ‘HKEY_CURRENT_USER\Control Panel\Desktop\’
4. Select ‘WaitToKillAppTimeout’
5. Right click and select ‘Modify’
6. Change the value to ‘1000′
7. Click ‘OK’
8. Now select ‘HungAppTimeout’
9. Right click and select ‘Modify’
10. Change the value to ‘1000′
11. Click ‘OK’
12. Now find

‘HKEY_USERS\.DEFAULT\Control Panel\Desktop’

13. Select ‘WaitToKillAppTimeout’
14. Right click and select ‘Modify’
15. Change the value to ‘1000′
16. Click ‘OK’
17. Now find

‘HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\’

18. Select ‘WaitToKillServiceTimeout’
19. Right click and select ‘Modify’
20. Change the value to ‘1000′
21. Click ‘OK’

That’s it. I hope you find these tips useful – you should now see a noticeable speed improvement if you make all of these changes correctly. Hopefully you’ll be pleasantly surprised!
