How to Use the Vista SP2 Disk Cleanup Tool

information   Information
This will show you how to run the Vista SP2 Cleanup tool to permanently remove the Vista RTM and SP1 backed up files created during the installion of the Vista SP2 to gain more hard drive space.
warning   Warning
Running the Windows Vista Service Pack 2 Disk Clean-up tool permanently removes the ability to uninstall the Vista SP1 and SP2. Do not run this tool unless you have no plans of uninstalling the Vista SP1 or SP2 and just want to save or regain hard drive space. The only option to remove them after using this tool is to do a clean install of Vista.
Note   Note
To see how much space you recover, make a note of how much free space you have on the C:/ drive in Computer before and after you run the SP2 Cleanup Tool.

It appears that most people are gaining on average 1GB of space back afterwards. :)




Here's How:
2. In the elevated command prompt, type compcln.exe and then press Enter. (See screenshot below)​
3. Type Y when you see Would you like to continue? and press Enter.​
NOTE: Tying N will cancel running the Vista SP2 disk cleanup tool. You can also just close the command prompt window to cancel to.​

4. It will take a little bit to finish. When it is finished, you will see the Windows Component Clean completed message. (See screenshot above)​
NOTE: You will see the Windows Component Clean was already run on this install message instead if you already ran this or installes Vista with a Vista installation disc that included SP2 with it.​
5. When it's done, you can close the elevated command prompt.​
6. Now, you just need to let all of us know how much space the tool cleared and saved for you. ;)
NOTE: I would happily tell you mine, but I have a Vista installation DVD that already includes the SP1 and SP2, so I have not backup files to clean up.​
That's it,
Shawn

Great find, mate. I just got 2.23GB back! :D I hadn't run the SP1-version of this tool. Very very happy, I'm on a tight budget (went from 4.47GB free to 6.7GB free!).

Fantastic stuff! :D

Wow, time for a bigger HDD
Haha, I have Vista on a separate 50GB partition (but it's a 640GB drive); short-stroking, if you've heard of it? Keeps all my Windows files on the innermost section of the disk and I think it helps a little:

Greetings, thought I'd share my findings. I took snapshots of the properties dialogs of the drive and the winsxs folder before and after running the SP2 cleanup tool. I had done a fresh install 2 weeks earlier with Vista, then SP1 followed by SP2. Take a close look at the Contains: Files, Folders section of the winsxs properties. Also the winsxs folder seems to have gotten way more space back than the drive it resides on.

Hello Brink,
I was hoping to get some feedback on my post, is it possible that my winsxs folder's properties is calculating it's size based on some uncompressed data in archives, there seems to be a significant difference ~1.2GB.
 
Hello Ruby,

Sorry about that. This is a perfectly normal amount of space to be recovered. When the SP1 and SP2 is installed, they create backups in case you want to uninstall them later. Using this SP2 Disk Cleanup Tool removes these backups to recover the space since you would not likely uninstall them afterwards anyway.
 
Hi Brink,

I think you meant to say a normal amount of space, anyway I understand what the tool does, I should have been a little more specific, there seems to be more space recovered ~2.3GB in my winsxs folder compared to my drive ~1.2. You would think that it should be the other way around.
 
Oh, DOH! :o

I'm not exactly sure why it would be like that either unless the data was compressed as you thought as well in the winsxs folder.
 
O.K. It seems with Windows there's always something. The reason I posted my findings in the first place was because of the amount of space people were reporting. My initial reason for the snapshot of the winsxs properties dialog was to see how many files/folders were actually being deleted. So I guess it's safe to assume that I recovered 1.2GB. Anyway I'm off to do a little research on this matter as my curiosity has now peaked.
 
Hi Brink,

I'm back from my brief research which landed me here. I believe it is beyond the scope of your tutorial, but thought you might be interested in my findings. From this I believe it is safe to assume that what the drive properties dialog reports is the correct space recovered. Am I correct?
