Windows Vista: Performance Information And Tools

The 'Performance Information And Tools' control panel allows you to adjust Windows features to get the best performance and user experience from your system. This is also where you can view the Windows Experience Index (WEI), which rates your system on a scale 1 to 5.9.

The higher the WEI rating the faster your system. If you get a WEI rating of 1 that could mean that you might not want to run Vista on your computer. If you get a 5.9 rating, that means your system is very fast.

Below is a list of the tools in the Tasks pane on the left side of the window in the Performance Information And Tools control panel:

• Managing startup programs (Help OS to load more quickly by preventing useless programs from loading).
• Adjusting visual effects (Turn on or off features that you like or don't use to get the best experience and performance).
  
• Adjusting indexing options (control how much of your system resources can be for indexing data on your computer).
• Adjusting power settings (Balance your power consumption vs. performance needs) .
  
• Open Disk Cleanup (Clean up your hard drive by removing useless file from it).
  
• Advanced tools (Contains: Event Log, Reliability And Performance Monitor, Task Manager, System Information, Disk Defragmenter, and more).
