By following a few simple guidelines, you can maintain your computer and keep it running smoothly and better performance.
1. Free up disk space
To use Disk Cleanup
Click Start, click All Programs, click Accessories, click System Tools, then click Disk Cleanup. If several drives are available, you might be prompted to specify which drive you want to clean.
2. Disk Defragmenter
To use Disk Defragmenter:
Click Start, click All Programs, click Accessories, click System Tools, and then click Disk Defragmenter.
3. %temp%
Click Start, Click Run, Type %temp% and Click Ok button and delete all files.
4. Prefetch
Click Start, Click Run, Type prefetch and Click Ok button and delete all files.
5. Do not run too many programs at Windows startup. Lots of programs load at once when booting up the computer will make the computer run desperately slow because of the insufficient system resources and memory. Go to Start, Run, type “msconfig” and press “Enter” to access System Configuration Utility, check “Startup” tab and uncheck the programs that do not need to run at Windows startup.
6. Do not use the ActiveDesktop. Otherwise, the system will run extremely slow. Open Group Policy by typing “gpedit.msc” within “Run” ->User Configuration ->Administrative Templates -> Desktop -> locate and disable Active Desktop.
