It was only a few days ago that Windows 7 SP1 was released, so… have you installed it yet? If you have, you’ve probably noticed that nothing too obvious has changed. I trust it will be rock-solid and honestly, so should you.
Now, did you know that when you installed SP1 Windows created what Microsoft calls Service Pack Backup Files on your hard-drive which roughly take up about 500MB of data? The files are used in the event you ever want to uninstall Service Pack 1 however if you never plan to do that (why would you want to???) that’s 500MB of dead/wasted space on your drive. Today I’ll show you how you can free up that space and reclaim 500 megs on your drive.
Is it safe to delete Service Pack Backup files?
Before just going in and erasing your files, you should know whether or not it is actually a good idea. If you erase your leftover Service Pack Backup files, you won’t be able to revert your copy of Windows back to normal by just uninstalling SP1. If this is your only option for recovering your computer in case of errors, then you might want hang onto these files until you are 100% confident that SP1 won’t cause you any problems. On the other hand, using Service Pack Backup files is hardly the best way to restore your computer…
As a responsible PC user it is a good idea to create a system image for your computer every few months, or before any drastic system changes (such as installing a Service Pack). This way if something happens, you can just roll back your entire system and there is nothing to worry about. If you’ve been using system images or another alternative for your backups, then these Service Pack Backup files are completely useless. Let’s delete them!
How to Delete Windows 7 SP1 Backup Files From Your Computer
Click the Window Start Orb and Type disk cleanup into the search box. Now Press Enter or just Click the program link.
The system will take a moment to scan, and then the Disk Cleanup window should appear. In this window Click the Clean up system files button that has a shield on it.*
*The shield means you will need to have administrator privileges in order to perform this action.
Windows will scan once again, and then bring you back to the Disk Cleanup window. This time more options will be available. Check the box for Service Pack Backup Files and then Click OK.
Windows will now go automatically start the process of deleting your Service Pack Backup files to free up space on your Hard Drive. In my case turned it out to be nearly 1GB of data! Just keep in mind that you should have a regular backup plan incase things go wrong, so deleting these files may not be the best thing for you if you don’t have any other backup options.
