Windows 7: Abnormally large Windows folder, size reduction possible?

Abnormally large Windows folder, size reduction possible?

Hi,

For a while now my Windows folder has been taking up more space on my 60GB SSD than I think it should. The size breakdown goes like this:

C:/Windows - 28 GB

- winsxs - 11.65 GB
- System32 - 8.45 GB
- Assembly - 1.63 GB
- SysWOW64 - 1.30 GB
- Installer - 1.17 GB
- Microsoft.NET - 1.03 GB
- SoftwareDistribution - 0.85 GB

I do regular registry fixes and temp file cleans, and I do regular inspections on my drives to remove unnecessary files and programs. However, the large increase in my Windows folder which happened about 6 months ago is really bothering me.

Is there any way get rid of some excess files? Or is this just a case of Windows inaccurately showing the actual amount of free space due to hard links?

Help is appreciated, thanks

Have you run disk cleanup?

Yeah I do it often, and I also remove the old windows updates.

I have a fully updated, but minimal, home premium x64 system here. Only bare windows updates. System32 is 3.1GB. WinSxS is 9.8gb.

So do you reckon the fact that I've installed every windows update available to me has caused both folders to expand?

If you've installed Recommended updates, that's going to affect it. Peripherals will affect it. And if the install has a long history of program installations, that's going to affect winsxs. Depending on the shell version, Disk Cleanup may offer system file cleanup as a separate function. This can add up to 3GB to the slimming, when it includes the service pack files, etc. But it sounds like you've hit that.

Yeah I've done all Disk Cleanup can do.

I'm just a bit annoyed, as somehow the windows folder has grown about 6 GB in 6 months.

Let me know if you ever come across this situation:
computer was working fine
cleaned? fixed? registry
computer now works noticeably better


Including the patches/updates offered yesterday, the Windows folder is 19GB (17.2GB after disk cleanup). This was gathered from a W7pro64bit virtual machine that has very little else installed:

As you mentioned, these values are impacted by hard links.

There are tools that let you see the size of folders as a column in a explorer like view. I just don't use tools like that - so I cannot suggest one. If you find one that you like, let me know and I'll see about installing it into that same virtual machine. Then we can locate which folder is abnormally high. That said, the Windows folder on this laptop is 27.8GB.

I use Folder Size (Folder Size - Free download and software reviews - CNET Download.com) to see the usage of my folders.

As for the registry files, it's just something I've always done thinking that it maintains optimal performance.
