 * System stops responding at the Welcome screen**

If you find that your Vista or Windows 7 computer suddenly stops responding and hangs up at the Welcome screen (after you enter your username and password to log on), this might be because of a deadlock in the Gpprefcl.dll file. Luckily, Microsoft has issued a hotfix to address this problem. You can find out how to get it in [|KB article 2526870].
