Hello,
I decided to instal SP 1 on my computer. I used Windows Update, but I only get this message:


I tried to install it manually, but got error too:


What shall I do to install Service Pack?

Make sure all third part firewalls and anit virus are turned off during download of updates.

Here it is:

Sorry for double post. But what I shall do now?

If you have any prerelease versions of SP1 installed, uninstall them before installing the final release version of SP1. Also, some antivirus software might prevent SP1 from installing, or might slow down the installation. You can try temporarily disabling your antivirus software. If you do so, be sure that you're aware of the risks involved, and be sure to re-enable it after the service pack is installed. Let us know if this helps.

Still same error ;/

Also I'm using Avast Free Antivirus, but turning it off didn't help

Hi Kothas, having read the above log please follow this guide which is related to the errors reported in the log.

I've just had a bad day with SP1 too. It was probably unnecessary to install SP1 because I've kept Windows 7 up to date. I think SP1 may be just a package of all those updates. It downloaded in about 30 minutes and restarted. The configuration went to 15% and locked up for over 5 hours. After restarting a couple of times with the button - never a good idea - I reached 100%. Windows update told me there were 7 important updates. I ignored that and ran the update manually where it decided no updates were required.

FIXED:
Sometime I was using Driver Sweeper. I ran backup option and everything fixed. Now I got SP. If something is not working visit:
