I have been beta testing SP1 for Windows 7 since August 2010, without any issues. I have installed all of the fixes, patches, and repairs. All have worked well without any issues. But when I went to install the final release of Windows SP1, I found two issues I needed to address.

The first issue was having to uninstall Windows 7 SP1 beta before installing the final release. You can uninstall the service pack which is actually listed as Service Pack For Windows KB976932 in updates. There is always that little voice in the back of your mind that tells you to pray that all goes well. Well fortunately for me, it did. After the uninstall and a reboot my computer started up and all was well.

The next issue I didn’t expect. I went to install Windows 7 SP1 final and received error 0x800f0a12 with a failed installation. I eventually found the reason listed at a Technet blog, followed the advise and fixed the issue. It appears that those who have Linux install need to make sure that the System Reserved or Windows partition is marked as Active before you install Sp1 final edition. Check out the link below:

I had previously downloaded the appropriately 1.90G file from Technet and burned the .iso image to DVD. This larger file from Microsoft is for both 32 and 64 bit versions of Windows 7 and also Server 2008 R2. The normal delivery of Windows 7 SP1 final, for most users, will be by Windows update service and will be much smaller in size.

I use a Diskeeper 2010 defragmentation software that works in the background and keeps my system running smoothly. In the past some people have mentioned that one should defrag a Windows system before an install major of updates such as service packs and when upgrading the entire OS. I am not sure if this claim still is valid, but you may wish to defrag your system and check for malware before installing SP1 on your Windows 7 system.

The installation window for SP1 recommends that you proceed with the installation because your system will kept your up to date plus it will enhance your systems reliability and performance.

Who doesn’t want a more reliable or better performing system? With this in mind I proceeded with the installation with my fingers crossed. After about 30 to 40 minutes of whizzing and restarts my machine came to life, update complete, and running hot, straight and normal. I checked my other software that has been installed and it all seemed to work OK.

So should you install Windows 7 SP1 on your machine? That is totally up to you. Over at AOL Tech they have an unofficial poll that indicates about 50% of those who did install SP1 had little or not problems. The next largest number was 30% who have decided to wait before install the service pack and about 20% who experienced issues.

If you have installed Windows 7 SP1, what has been your experience? If you haven’t installed the service pack, are you waiting until the bugs are worked out?

Comments welcome.
