Windows 7: Large installer and winsxs folders

Large installer and winsxs folders

My windows/installer and windows/winsxs folders are 12.7gb and 12.1gb respectively. In fact, my windows folder takes up 40gb of my 68gb of usable space.

I've done some reading about this and people seem to say not to clear these out and instead to just uninstall software. However, when going into "Add or remove programs" all of my software only adds up to 2gb total. So how are there 12.7gb of installers/uninstallers for 2gb of actual software? Surely there is lots of unused stuff in there and in the winsxs folder, can I clear them out?

Hello Vcize,

The folder "%WINDIR%\winsxs" mostly consists of hardlinks to system files, backup of Updates and multiple DLL file versions to keep compatibility with programs.
So yeah it is big, but the size is also fooling us cause hardlinks point to a single file to reduce hard disk space, though Explorer does not know that, so the size is much smaller than it seems.

To decrease the size, first fully update your system to get the update for the option 'Windows Update Cleanup' in 'Disk Cleanup' which came originally from Windows 8.

Also i recommend you use Ccleaner to remove other kind of temporary files and history.

Good luck ^^.

Unfortunately I've already done the disk cleanup that includes Windows Update Cleanup. I will give Ccleaner a look.

You could try a decent uninstaller and see what that reveals.

If you have been using your install for a long time and you have installed a lot of software (even if you have uninstalled it) space seems to be gobbled up for no apparent reason.

When I have performed a clean install and reinstalled the latest versions of the software I use, the overall size of the install is smaller.

Here's my OS partition:

I suspect that in a few months time I will be using more space, even if I don't install anything new.

I have an ultrabook with 128 GB of space, 101 GiB after partitioning and so on, so it got annoying when I just checked my C:\Windows directory and it was up to 25 GBs, with winsxs up to 14 GBs. I had heard on Windows Weekly that there was a way to clean up the winsxs directory now, so I followed...

Want to sync large folders (300GB) Alternatives to Synctoy?
Synctoy is very slow-is there something that is faster/better to back up my media folder? One hard drive is primary-the second one is the backup... Or is it going to be around the same speed for anything that large?

Explorer SLOW on large folders
I'm finding Explorer to be extremely slow on large folders (containing 2,000+ files for example) Much slower than Vista and insanely slower than XP. It seems to REALLY be tryng hard to peek at every file and gleen info from them every time you open the folder instead of just populating the list...
