Increase Aero Peek Desktop Preview Mouse Hover Delay

You can use the registry hack discussed to adjust Aero Peek Desktop Preview Mouse Hover Delay in Windows 7. It's also easily to do.

1 Click the Start menu, and type Regedit.exe in the run box and press ENTER.
2. Navigate to the location as:

HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Advanced

3. Create a new DWORD 32bit value and name it as PreviewHoverTime
4. Then double-click PreviewHoverTime and click Decimal toedit the value. I type 3000 in the value data box. 3000 value means that you increase the hover delay to 3 seconds.
5.Close the Registry Editor and logoff.
6.After you login back, you can delay it further more to avoid accidental preview of the desktop in windows 7 now.
