Windows 7: Problem installing Service Pack 1 (SP1)

Problem installing Service Pack 1 (SP1)

I have a PC running windows 7 64-bit and I am finding it impossible to get windows 7 Service Pack 1 (SP1) to install. I start the installation and it seems to run for more than an hour and appears to be installing OK; but when I restart the PC I get an error saying that the installation was not successful and it the rolls back to where it was before I started the installation. I have tried to install a numbr of times, but without success.

I have also tried:
* Stopping all non-essential start-up items by disabling them booting on startup using msconfig.
* Stopped all firewall and anti-virus from running during installation
* Run the Windows Update System Readiness Tool (kb947821) before the installation
* Run the Windows Update troubleshooter
* Running the installer from within Windows Update, as a standalone x-64 bit installed downloaded from Microsoft, and as an iso file burned to a DVD
* Run sfc.exe /scannow which reported no errors.
- but none of these have had any success

Other Windows Updates seem to install OK - it is just the SP1 update that refuses.

[For info: I have another PC that I recently updated (clean install) from XP to Windows 7. I had a similar problem on this PC after I had performed all the other Windows Updates and instaleld my normal suite of programs. SP1 also refused to install. In the end, I reistaleld Win 7 from disc and then immediately installed SP1 before installing any other updates or programs. SP1 installed OK. However I do not want to follow this route on my main PC as it has a load of programs installed which will take a few days to reinstall if I have to start from scratch].

Can anybody advise how I might install Service Pack 1?

Many thanks in advance for your help.

Nice detailed post. Well done.

* Clean up all Temp files...
Start > run > ok > organize & select all > organize & delete. { note some you may have to skip>}

JMH - Thanks for the advice; I'd already tried most of these without success.

However:

Finally figured out what was happening following a user on another site who also had this problem. Even though I stopped all non-Windows programs from starting on boot-up, a few additional programs kept on running. One of these is a security program called Trusteer Rapport. In the end I had to uninstall this program, and then SP1 installed OK. I subsequently reinstalled the program.

Wierd that it would stop SP1 from installing (and not other Windows updates, and without any notification) but Windows often seems to be full of wierdness!. Anyway problem solved for the moment..... until SP2 comes along I guess.

Cheers
