All of a sudden, Windows Explorer takes 20 to 60 seconds, to just pop up the Search dialog box( right click a folder and select Search...)
When I try other actions on the Windows Explorer, the title bar shows 'Not responding..' but eventually the Search dialog box pops up.
All I can think as the cause was to delete a couple of old/unused installation update directories from C: drive.
I do a lot of file search, and this is a big pain. How to fix this problem?
