Windows 7 SP1 Problems
I have just started reloading my system for the third time! Each time, after loading SP1, problems started showing up such as system files causing a UAC error due to "unknown" supplier. The other very noticeable thing is that the machine slows down, almost seems to be running in Stealth Mode. Looking 'Problems after Windows 7 SP1 update' in Google gives a number of links some of which are from Microsoft Technet. seems there are a number of people affected this way. At present, although SP1 is shown as an "Important Update", it is not ticked when you look at Windows Update.
Seems that it affects some systems more than others, so my advice is that unless you have a clone of your system do not update yet! I'm going to wait and see whether MS admit to having problems. It seems to affect high end machines more than mid-range, my wife's Inspiron 15 works OK but my Studio XPS1640 and AW M15X both seem to have problems.

Thanks for the suggestion Tesla.
I have tried your suggestion and stripped the system off. I then reloaded Windows 7 Ultimate 64bit onto the drive and loaded the chipset drivers (Intel Ibex Peak PCH Chipset A00 R232275) after rebooting I then shut the system down. Using a stopwatch, I restarted the system and measured the time to the Windows log on prompt. This was 53.75 seconds. I then loaded Windows 7 SP1 from a DVD loaded with the MS iso file, after the update had completed I again shut the system down. I then repeated the measurement of how long it took to load to the log on prompt. This time it took 1 minute 38.18 seconds (98.18 secs) an increase of 183%, I would have expected times like this if Stealth Mode was running, but I can confirm it was not.
Some of the comments on MS Technet confirm this extreme slowdown with Windows 7 x64 versions, so it just confirms that something is seriously wrong with SP1. I think that MS will have to find out why SP1 slows the system down so much, maybe it is still a beta version?
My system:
M15X, i7 620M 2.67Ghz, Radeon Mobile HD5730 1Gb, 500G 7200RPM Seagate HDD, 8Gb 1333MHz RAM, 1920x1080 WLED display, Matshita BD-RE UJ235A Blu-ray Drive

Have just removed Service Pack for Microsoft Windows R976932 and repeated time check, 55.41 seconds. Update for Microsoft Windows KB976902 is not uninstallable. From these results it proves that SP1 screws the startup times for x64 versions of Windows 7.
Lets hope MS sort out the problem(s) SP1 causes to have this drastic an effect!

Just checked what updates were loaded as machine was offline at all times and found two, KB976932 Service Pack for Microsoft Windows and KB976902 Update for Microsoft Windows. I uninstalling both and will check whether the time to log on have returned to around 54 secs.

Yes, taking Image Backups along the way is what I do also (in case you fall into a hole you can't dig your way out of).
On the problem machines ...
- Try installing Win-7 fresh. Let it start for the first time and then reboot.
- Install only the main Intel chipset driver
- Then install the full stand-alone version of SP1 (that you downloaded previously ... to a flash drive, etc.).
- Reboot and see if machine is working
- Then, continue loading drivers in the proper order (video, sound, etc.).
I don't know why you are having a problem, but that might take care of it.
