How to Fix Windows Components in Vista

1. Click 'Start,' 'All Programs,' 'Accessories,' 'System Tools' and then 'System Restore.'
2. Click 'Choose a different restore point,' and then click 'Next.' Select from the list of restore points the date and time when the Windows component last worked. Click 'Next.'
3. Click 'Yes.' Windows will restore your computer to the selected date. When the operating system restarts and the System Restore dialog box appears, click 'OK.'
4. Use antivirus software to scan your entire computer for viruses. A virus infection can prevent Windows or the application from running properly.
5. Click 'Start,' 'All Programs' and then 'Windows Update' after the virus scan is complete. Click 'Check for Updates.' If any new updates are found, or if you have updates already waiting to be installed, click 'Install Updates.'
6. After Windows is finished installing the new updates, run the Windows component to check whether the previous fixes resolved the issue.
7. Click 'Start,' and then click 'Search' if the component is still malfunctioning. Type 'cmd.exe' in the search box, and then press 'Enter.' Right-click 'cmd.exe,' and then click 'Run as an administrator.'
8. Type 'sfc /SCANNOW' at the command prompt to run the System File Checker utility. Windows will scan your computer for any errors and attempt to repair them.
9. Restart your computer after the process is complete. System File Checker will restore Windows' factory settings.
