Service Pack Cleanup Tool In Vista SP2 To Clean up Old RTM & SP1 Backup Files
The recently released Windows Vista SP2 has shown significant enhancement and improvement in terms of compatibility, reliability, performance, and speed compared to the earlier SP1. If users had noticed, after installing the Vista SP2, the hard disk’s space had been taken up substantially. This was mainly because a lot of old Vista RTM and SP1 backup files and components were not deleted upon the installation of new SP2.
To housekeep your hard disk and clean up those old and unused SP1 backup files, users probably can try the new Service Pack Cleanup Tool which is also named as compcln.exe. This successor for SP1 cleanup tool, Vsp1cln.exe, can easily remove all the system files (RTM & SP1) inherited from the older versions but replaced by Vista SP2.
Running this compeln.exe tool is pretty simple:
1. Click Start>All Programs>Accessories>Command Prompt or click Start>Run and type cmd to open Command Prompt Windows
2. Execute the command “Compcln.exe”. The path is “c:\Windows\System32 \compcln.exe”.
3. Users will be prompted a question whether to keep Vista SP2 permanently in the system.
4. Once users type “Y” and press enter, the system will start performing the windows components clean.

After the cleansing process, users will notice the free hard disk space has increased substantially.

Am I supposed to get “Windows Component Clean was already run on this install” if I re-run Compcln.exe?
I noticed it only freed up about 0.2GB of free space on first run so I re-ran it several times and no message was returned – the app simply exited after running for a few minutes.

SP2 works gr8, removed the extra files with this tool and freed up about 1 GB (ran the SP1 cleanup tool before and gained about 2.5 GB)

@misc:
Your winsxs folder isn’t taking up 12.5 GiB on your HDD. Don’t believe anything explorer shows you. If you like to know more on the subject I suggest you Google it..

ffs, I installed SP2 hoping that it / I could finally delete this damn winsxs, which is taking up 12.5 GiB already on my 30 GiB Vista partition (which now has only about 1.4 GiB free space left).
Any news if it’s safe to delete now?

to Peer, RTM-escrow has been released to testers, and has leaked. Unless there is HUGE HUGE issue in this build, this will be the final version that rest of mortals will be able to download in about 2-4 weeks.

The artcle reads ” … the recently released [] SP 2.[]“. No ! SP 2 has NOT been released at all. It is a RC, not RTM. As such it provides a “Black-Box”-like look at the new functionalities it provides. That’s all there is to it. Remember NT 5 ? or Windows 2000 ? Three Betas and Two RCs. Never dreamt of using it productively !
@Vista_Boy: now you get the point ? Don’t use RCs or Betas on PRODUCTIVE machines. Or in other words: don’t install and use unless you know what you are doing. Or before you read the Relaese Notes and / or Technet Arcticles. You wanna play ? Use Linux !
