"We had to destroy the village in order to save it."
Now where have I heard that before?
Despite its fluffy name a Windows Refresh is about the most destructive thing you can do to a computer short of a nuke and pave and should be treated as a last-ditch method that you only use once everything else has failed. It's an admission of defeat - please don't do that.
Windows Refresh is also a nice example of how Microsoft is reducing all personal computers to the level of disposable tablets - if it doesn't work right, wipe and reinstall or throw it away and buy a new one. Don't think, just spend!
