Remove Windows 7 SP1 Backups To Free Up Disk Space
HomeForumWindowsLinuxSoftwareInternet ExplorerFirefoxChromeOperaEmailArchivesContactAdvertise Author: MartinWednesday February 23, 2011Remove Windows 7 SP1 Backups To Free Up Disk Space TweetShareThe first service pack for the Windows 7 operating system has been released yesterday (see Windows 7 Service Pack Update Downloads Live) and it seems as if most Windows 7 users did not have troubles installing the update. Service packs are installed with an option to uninstall them again, which is helpful if incompatibilities or stability issues occur after the system has been updated.
Then again, users who have installed the service pack without complications do not necessarily need those backup files that allow them to uninstall the service pack anymore. These users can free up disk space on the Windows partition by deleting the backup files.
I recommend to test the operating system with service pack at least for a few days before you make the decision to delete the backups. Impatient users may create an image of their system partition instead that they can use to restore the system if the need arises to uninstall the service pack after the backup data has been removed from the system.
How much disk space are we talking about? I just made the test on a Windows 7 Professional 64-bit system. The free space increased from 18.9 Gigabytes before the cleanup to 22.2 Gigabytes after. That�s more than 3 Gigabytes of space. It is likely that 32-bit users will be able to free up less space than that due to the nature of their operating system. Still, they will free up Gigabytes as well.
The easiest way to remove the backup files of the Windows 7 Service Pack 1 installation is the following. Open an elevated command prompt. You do that with a click on the start orb, the selection of All Programs > Accessories, a right-click on Command Prompt and the selection of Run as Administrator.
Use the following command to free up disk space after the service pack installation:
dism /online /cleanup-image /spsuperseded
The process takes a few minutes to complete, it ends with the sentences �Service Pack Cleanup operation completed. The operation completed successfully�.
Please remember that you cannot uninstall the service pack after you have cleaned up the disk space. Please let me know how much disk space you freed up with the command.

Cool. It seems it is not that easy like in previous versions to simply delete the blue $NTUninstall*** folders.
Will try it soon.
ReplyMike says: February 23, 2011 at 4:17 pmAfter SP1 install
Free space = 341,576,028,160 bytes
After dism cleanup
Free space = 340,173,201,408 bytes
So, roughly 1.3Gb.
ReplyMartin says: February 23, 2011 at 4:34 pmMike was that a 32-bit installation?
ReplyMike says: February 23, 2011 at 6:14 pm64 bit.
Manmohan Rajyana says: February 23, 2011 at 4:18 pmMy Action Center has already downloaded and installed Windows 7 SP1 which is working fine as it does not include new features but instead is a collection of security patches and non-security fixes with an updated Remote Desktop client.
Windows 7 SP1 can be uninstalled by selecting the �Service Pack for Microsoft Windows (KB 976932)� item using the operating system�s control panel and uninstall tool.
Where remains any apprehensions ? Well I have removed earlier backup & made fresh Backup
Back-ups I make on a portable Hard Disk as suggested by Geeks
Freeing up disk space with to-days hard disk capacities, has no complications
~1.3 GB disk space recovered on 32-bit Win7 Ultimate.
ReplyMartin says: February 23, 2011 at 4:44 pmThanks, so it is fair to assume that 32-bit users can free up 1.3 Gigabytes, and 64-bit users 3 Gigabytes. I assume you have installed the service pack via Windows Update?
ReplyDavid says: February 23, 2011 at 6:55 pmYes, installed via Windows Update.
Mushaf says: February 23, 2011 at 5:19 pmI did it yesterday just after updating to SP1 and I freed up 540 MB of disk space using the disk cleanup utility (Win7 32 bit).
ReplyManmohan Rajyana says: February 24, 2011 at 2:47 pmMr. Mushaf,
I too happen to free up approx same MB of disk space by using CCleaner and WinOptimizer before making my fresh Back-up which I did after deleting earlier backups from my portable hard disk.
My Windows 7 Service Pack 1 was uploaded by Microsoft through update center and they downloaded and installed approx 25 updates; and last one was of 157 KB followed by 61.2 MB despite that I could free up approx 540 MB when I cleaned up my system
I didn�t understand as to how that happened ? ?
You people are geeks; may like to enlighten me
ReplyKhai says: February 23, 2011 at 5:31 pm64bit user, freed about 1.5 gb
tho I didn�t use the windows update version, I downloaded the full 1.9gb ISO (I prefer to have the full SR on hand for reinstalls etc)
You weren�t kidding about waiting a couple of minutes before seeing the �The operation completed successfully.� Took about 5 � 7 minutes for the cleanup to complete.
To answer your request: Windows 7 Ultimate, 32-bit, ~4 GB of disc space cleaned up after running this command. (previously 138 GB free space, moved to 142 GB Free).
Cheers for the command.

ReplyDanTe says: February 23, 2011 at 7:31 pmI noticed after install, Windows Media Player goes through a setup process all over again. Did it change?
Also, my ZoneAlarm firewall stated that .Net optimization service is new and request permission. This changed too?
ReplyCurious says: February 23, 2011 at 7:41 pmMike had less free space after the dism cleanup (341 gb before vs. 340 gb after). Is that the point of the cleanup?
ReplyMartin says: February 23, 2011 at 7:49 pmLikely an error on his side and not an error in the cleanup.
ReplyMike says: February 23, 2011 at 8:06 pmYep, that was me being tired!

Replydanijel00 says: February 23, 2011 at 9:07 pm1.3gb on 32bit/windows update/home premium version� but the installed SP took up some space (i have a 40gb ssd, so every byte counts)
ReplyAnonymous says: February 23, 2011 at 9:11 pm1.5 GB. Win 7 32bit

ReplyJohn says: February 23, 2011 at 9:38 pmWin7 64bit virtual machine. I used the DVD ISO version
Reclaimed 1.77 GB
The SP1 setup files are listed under �disk cleanup� in windows explorer. All you have to do is �check� the box. No CMD line needed.
Cleared up 650MB on my x64 box�but my SP1 D/L from Windows Update was only ~80MB (fully patched machine before SP1).
I suspect anyone reclaiming several gigs probably hasn�t done much housecleaning lately.
ReplyMartin says: February 23, 2011 at 10:01 pmThey were not listed in my case.
ReplyDerek says: February 24, 2011 at 1:12 pmThanks for the tip Martin. Saved ~1.5Gb Win7 x86.
mizkitty64: There was indeed an option to remove service pack backup files in Disk Cleanup (whether or not it was there before installing sp1 i�m not sure) but no space could be gained by ticking this option � it stated 0kb.
