Windows 7 and extra 12 GB upon install

Apotter · 10 Feb 2010

I just noticed that Windows folder is almost 30 GB (1/3 being used by winsxs.. wasnt that dlls cache?) .. and a couple of TeamViewer log files each ~2 GB.. this is odd. Now this may explain my missing space but also makes the windows installation message I got meaningless... unless all windows files have copies in case one goes bad.

Well, thanks guys, I don't think there is much to be done about Win7 taking so much space. I'll be perfectly safe in the future with the near 20 GBs we just freed.

A 30GB Windows folder is pretty darn big. On my work laptop (32-bit enterprise 7), I'm using 9.67GB according to Windows Explorer. On my work desktop (64-bit ultimate 7), I'm using 11.9GB.

As stated before, the WinSXS folder is VERY misleading;
WinSXS Folder not actually consuming lots of space

Run something like TreeSpaceFree and see where your space is going in C:\windows.

Here is mine from my 64-bit system for reference;

In Explorer Winsxs is reported 0 bytes and 0 files, although i see files in it. I checked drice C with a small tool i dug off the net (Primitive File Size Chart) and Winsxs is reported 8.97 GB there. About the total Windows folder size... well, I was mistaken.. it's actually 24.52 GB - I was looking at the wrong row. Still this is quite more than what's supposed to be..

Please download TreeSizeFree from the web and tell it to scan C:\windows and post your results. We should be able to flush this out.
