Hi!
Today I heard about serious problems when installing Service Pack 1 on Windows 7 x64 systems, e.g.:
- http://forum.chip.de/windows-7/windows- ... 90290.html (German)
- http://forum.worldofplayers.de/forum/sh ... p?t=958404 (German)
- http://social.technet.microsoft.com/For ... 8ff9344308 (English)
- http://social.answers.microsoft.com/For ... e44768abb8 (English)
These installations encountered an error code C000009A when modifying the registry, which resulted in a totally broken system state: No reboot, no safe mode, no recovery point helped
The solutions for this problem given in

use dism.exe (see http://technet.microsoft.com/en-us/library/dd744311(WS.10).aspx) and are quite complicated, maybe too complicated for "normal users".
Even though I successfully installed SP1 for Windows 7 x64 on both a physical and a virtual machine, I thought I should mention this and, obviously and in advance: This is not my problem, but Microsoft's
So be careful when you decide to install Service Pack 1 on a Windows 7 x64 system: A complete backup (disk image) could be a good idea...
