Well, it’s that time of the season again where Microsoft pushes out a new service pack. This time it is Service Pack 1 for Windows 7. I have actually been running SP1 for a few weeks now (yay for developer’s releases) on 3 different machines, all with zero problems. The install is smooth and the service pack didn’t cause any issues.
As with the service packs for Windows Vista, there is a command you can run for your command line that basically permanently installs the service pack files on your machine (by removing all of the backup files it makes during install). I previously showed you how to do this for Vista SP1 and Vista SP2, so now it is 7 SP1’s turn.
Also, as with previous SP release, Microsoft has once again changed the command to make this happen. I’m not sure why they always want to make you play guess-the-command, but I did the research for you, and here it is. Run this at an Administrator command prompt:
dism /online /cleanup-image /spsuperseded
It will take a few minutes to run and do its thing, but once it is finished you will get back around 1.3gb to 1.5gb of space. Not bad for running 1 command at the command line! Just remember, this command does make the service pack install permanent, so there is no reverting after this, but honestly, once you have booted a few times and everything works fine, there is really no reason to ever want to revert.
So go claim back your space!
