Go to “My Computer” and right click on your hard drive. At the bottom of the window that opens, you should see a check box titled “Allow Indexing Service to index the disk for fast file searching.” Uncheck it.
Press OK and you’re done! Your computer should be a little faster after a restart.
Chkdsk (Chkdsk.exe) is a command-line tool that checks volumes for problems. The tool then tries to repair any that it finds. For example, Chkdsk can repair problems related to bad sectors, lost clusters, cross-linked files, and directory errors. To use Chkdsk, you must log on as an administrator or as a member of the Administrators group.
You can also run Chkdsk from My Computer or from Windows Explorer.
Click the start button
Right-click “My Computer” and select “Explore”
Right-click the disk you want to check and select “Properties”
In the properties dialog click the tab “Tools”
Click “check now”
The “checking disk” dialog appears, check both options and click start
You will probably see a message that chkdsk wants exclusive access to the disk and therefore wants to begin first thing after you restart your computer. Accept by clicking ok.
Restart your computer
When your computer restarts you will see chkdsk advancing through several different stages of verification, examining your hard disk. If it detects no errors, Windows will continue to start to your normal desktop. If there are errors, chkdsk presents a report with what it has done and waits for your confirmation.
