New Windows 7 feature in KB 2852386 reclaims wasted space on your C: drivePosted on October 9th, 2013 at 19:21 26 comments
I took back 3.2 GB of wasted space on a well-worn Windows 7 machine. This is like free money.
Thanks to SB for the tip…

Ummm… link’s not working, there. It leads back to this page, not onward to “Windows News”.
A few minutes’ googling doesn’t show me what the right www address might be.
Initial reaction to the title: Is this not what add-ons like CCleaner and Windows features “clean up disk” or perhaps “defrag” have been doing for years?

Gave the utility a try. Microsoft’s Disk Cleanup, run with System Files requested, found 4.33 GB. Ran the cleanup successfully.
While this is a small amount of my total disk space, it represents a nice decrease in the amount of time and disk space needed for my regular “system image” backups. The only downside I found was the amount of time that was needed to do the cleanup.
The computer needs to be shut down and restarted to complete the task. Windows spent almost 10 minutes doing the configuration and cleanup procedures before I got back to my password request screen on rebooting.
I got the the article, clicked on the link to manually install, then had to go through the Windows validation process. I chose the alternate validation. As part of that process, I clicked a “Continue” button to download the Windows Validation Tool and get a code. I’ve done this before.
It installed and then told me that MSoft no longer supports that version of the Windows Validation Tool — the one they *just* installed for me. The solution is to download the newest version.
Downloaded & installed KB-2852386. Subsequently deleted 4+GB of SP and update droppings (it’s an OLD Win7 install).
I got back only about 600 megs out of a winsxs folder that is still almost 7 GB large. That’s quite a big chunk of what looks to be wasted space on my 128 GB SSD, especially when the initial windows 7 install is about 30 GB — the winsxs file is up to 25% more overhead for what benefit?
Thanks for your help, fellow posters.
I mistakenly included “Windows News” in my Google search, thinking that was the name of the website. Thass’why I couldn’t find the article.
You gotta click on the brown colored Techwatch next to the InfoWolrd to get to the story.

It’s nice that they’re finally giving back some of the gigabytes of hard drive space they’ve taken with their Updates, Patches, Service Packs, etc. for Windows, IE, Office, Net Framwork, etc., etc., etc. I wish they could have done this back when I only had a 20 Gig. hard drive.
I tried to past a relevant comment here last Friday, which was said to be waiting approval for days, and now it has disappeared.
I wonder if the feature of KB2852386 is built in Windows 8.1.
Is there anything like this available for Windows Vista 64-bit?
My WinSXS folder has almost 90,000 files in it and is over 25GB in size!

Does using this cleanup feature interfere with Service Pack upgrades?
What am I thinking — they’ll never issue a Widnows 7 SP2! But for Windows 8 users — future Service Pack upgrades are inevitable, yes?
But what about some of the deeper kernel level patches? Possible issues if this feature is invoked?

As you say Woody. Excellent. Thanks for the tip.
Why Did you delete my prior response to Sethness’s question on how to open the TechWorld webpage . Apparently he was clicking in the wrong on the wrong area of the page to open te site?
Not sure what happened, but I didn’t delete anything…
Haven’t heard of any issues. You’re getting rid of the very old backups…
Nope, it’s Win7 only.
I’m not sure, but if MS updates Win 8.1 in a year, you’ll be able to get rid of it.
I snuck away for a long weekend. Sorry.

A few things people may want to know about this. I’m running Win 7 64-bit and using Firefox. If you try to download this update by going to the KB article page (linked in Woody’s article), you’ll first be required to download a Windows Geniune Advantage GenuineCheck.exe program, and when you try to run it, you’ll get an error message that it’s not the latest version. It turns out (as I understand it) that there is no latest version, and that what you need to do is use Internet Explorer (rather than Firefox or any other browser) to visit the KB article page and download the desired update. (Or, alternatively, download the update by way of Windows Update, but I didn’t like the idea of unchecking all the other checked updates.)
Second, when I ran Disk Cleanup after installing the update, a progress window showed up and then, at a point where it showed around 30% or so complete, the progress window simply vanished with no message, leading me to wonder if something had gone wrong.
Since you have to restart Windows anyway for the benefits of the enhanced Disk Cleanup to take effect, I restarted. Windows then took a long time to even reach the shutdown screen (leading me to wonder if the PC was frozen), and then a minute or two “configuring” before the restart happened, and then the blue startup screen showed a “configuring” message, and then a “cleaning” message, and it was close to [I]half an hour[/I] (I’m not kidding) before the boot finished. (I again wondered if the process was frozen.)
And it’s not like I had an unusual volume of old update files to be deleted. I had 2 GB, which sounds like it’s pretty typical. (I bought this PC in January.)
Has anybody tried if it’ll work with Win7 that doesn’t have SP1?
Never mind. I just thought I try it — downloaded fine (via validated download, using IE), but then says “The update is not applicable to your computer.” Too bad; my Winsxs folder is 6.75 GB.
I found this October 2009 TechRepublic article that discusses how to reduce the size of the WinSXS folder in Windows Vista (SP1 or SP2):
Reduce the size of the WinSxS folder with vsp1cln.exe and compcln.exe

I think SP2 came out in May 2009.
The compcln.exe (Vista SP2 cleanup tool) makes SP2 permanent.
My concern is this:
What are the implications of running these clean-up tools, after more than 4 years since these service packs have come out for Vista? In short, is it safe to run these clean up programs now, in 2013, with four years of subsequent updates patched on top of SP2?
Also, has any brave soul tried to install the Windows SP1 clean up addon – on a Vista system?
