windows 7 and wmi repair
a friend sent me an im today asking if i had experienced a situation with windows 7 that generally acted "funky", seemingly hanging applying settings, and such. what he determined from trace evidence is that wmi initiated a repair, but it wasn't initiated by an admin.
i told him i could have sworn i had seen where windows 7 behavior changed and initiated a self-repair when it found certain conditions to be true. (i, of course, cannot find this anywhere now so if you know where it is, please leave a link in the comments!)
long story short, windows 7 does initiate a self-repair. it isn't immediately evident in this article, but this article talks about a hotfix which suppresses unnecessary full diagnostics -- which can be cpu intensive, causing the problems my friend experienced. from the article:
When you perform one of the following operations on a computer that is running Windows Server 2008 R2 or Windows 7, the operation may take a long time to complete:
- Start the computer
- Log on to Windows
For example, the computer takes three or more minutes to start.
