After a short while, the temp directory filles up with hundreds of temp files that always get scanned over when Windows starts up and when programs launch. This slows everything down immensely.To delete Temp files, make sure no programs are open, First, make sure that you can see hidden folders. Double-click My Computer.

4) Check your hard disks for problems.
Double-click My Computer. Right-click the C-drive and click Properties. Click on the Tools tab and choose to check the computer for problems. Click on Check Now. You will then have two check boxes. The top option is for the file check, and the second option is for the hardware (physical disk) check. Check either one, or both. At least check the top one. Hit ok, and reboot. This may take some time, but let it run . Or, you can do a few of the performance tweaks yourself, if you have Windows XP. By default, everything is turned on in Windows XP. It isn't very streamlined for performance, but rather for appearance. You can turn off a few of the unnecessary features, and Windows will still work just fine, and maybe a little faster.To do this, right-click on My Computer and click on Properties. Click on the Advanced tab. Under the Performance section, click on the Settings button. On the Visual Effects tab, you will see a list of check boxes. By default, these are all on. You really don't need any of them for Windows to run. Go through the check boxes one by one, and determine which ones you can and can't live without.

5) Turn off Active Desktop.
Active Desktop turns your desktop into a web page, and allows you to have things like a real-time calendar, and up-to-the-minute weather or stocks. These are nice, but really slow down your computer. And even if you don't use Active Desktop for anything, just having it active can cause a performance decrease. Turn it off.Now, right-click on the desktop and in the pop-up menu, choose Properties. On the Desktop tab, choose Customize Desktop. Now, on the Web tab, make sure that there are no websites chosen here. If there aren’t any, then Active Desktop is not on. Cancel and go back to the desktop.

6) Configure and Streamline MSCONFIG.
One thing that really causes a huge performance decrease is to have unnecessary programs running in the background. Some of these programs can be seen in your System Tray (located next to the clock). These are tiny programs that are robbing you of memory and processing power. Some of them you need, while most you don't. Some of the programs you DON'T need are printer icons, CD burning icons, shortcuts to programs (such as video settings), AOL, any Instant Messaging Programs, etc. Just because these programs aren't always running, doesn't mean that you still can't print, burn CDs or Instant Message. They can all be run from a shortcut.
Or You can use a utility, called MSCONFIG, to turn OFF unnecessary Start Up items.click on Start->Run -> type msconfig. Click on the Startup tab. This is a list of everything that is running in the background, some of which show up in the System Tray. Now, be careful, some of these you do need. Some items to keep are Ctfmon.exe . Others, you can uncheck, such as NeroCheck, ypager, qttask, AOL, and any other Instant Messaging programs, or printing programs. Remember, if something doesn't work, because you turned it off, it can always be turned back on. You just have to reboot every time you make a change here. But, as you uncheck the unnecessary programs that run in the background, you will see that Windows loads much faster, that there are less icons in the System Tray, and that your system is much more quick to respond.
After you reboot, you will have a window that says that the configuration utility was edited. Click check not to show that in the future, a check box at the bottom. This just means that there was a change made to the MSCONFIG.

7) Defragment your hard drives. to efficiently defragment a hard drive, it likes to have 25% free space. It can still do the defragmentation with only 15% free space, but it takes quite a bit longer. If you can, delete any unnecessary files before deframenting your drives.To defragment your hard drives (in any Windows operating system), double-click on My Computer. Right-click on the c-drive and click on Properties. Click on the Tools tab and choose the bottom button, to Defragment Now
