TrustedInstaller, Getting rid of W7 files from W10

Wed Apr 17, 2019 4:31 pm

Playing with the Winsxs folder (50,000 files).
I can not just edit the permission for the Winmsxs folder. Access denied.

I can edit permissions on ONE file and deleted that one file but 50,000 of them...no

Tried to move them and actually got 10,000 of them to move & deleted them.
Only 40,000 to go.

Oh yes, I was removing permissions from the TrustedInstaller and it vanished. Can not seem to get it back to "deny" it.

Thoughts Welcome.

Yeah, I'll second the Linux live USB option. It'll do exactly what you want and ignore Windows' overcautious squeamishness. Just be careful.
Work: Core i9 7940x, 32 gigs RAM, Vega 56, Windows 10 Pro
Play: Ryzen 7 1700, 16 gigs RAM, GTX Titan Xm, Xubuntu 18.04
Why?: Athlon X2 5050e, 4 gigs RAM, Radeon 7670, Xubuntu 18.04

Hmm ok, going to try a linux live usb. Downloading now.
Just hope it shows the Windows drive names and not just "Samsung drive xxx" and "Samsung drive xxx"... hate that.

Thanks!

You're going to wind up breaking your Windows install.

a) Don't do that.
b) If you're trying to free up space, keep in mind that Explorer mis-reports directories with hard links in them, as Explorer is dumb and counts each file separately, even if they point back to the same data stream.

This article has a few pointers and legit tools you can use to help reduce the size of the winsxs folder, but the TL;DR: is don't mess with it unless you enjoy reinstalling Windows from external media.

If you are just wanting to delete files from the previous OS installation you can do that from disk cleanup and go for the cleanup system files button. It includes some things in the WinXsS folder.

If you just want to shrink your WinSxS folder then use the command line as mentioned here, it'll probably find 200MB to 1GB of upgrade/update related files to clear based on the age of your install https://www.laptopmag.com/articles/clea ... save-space

Ok, it was installed as a dual boot W7-(partition C) and W10-(partition W)
Not an upgrade by W10 so there is no "Windows.old" stuff to delete.

I have it set to boot directly to W10 and want to make more room on C just not sure exactly what all I can delete on "C" without messing W10 up. I"m thinking that I should be able to delete all of the W7 C: "Windows" directory.

At least I have it imaged in case I go too far. Don't want to nuke everything and reinstall W10 Clean.

Thanks to all for the links.

I would back up stuff I need, and just do a clean format and install of w10 when it's released in may.
