Why wont windows 8 let me delete windows.old. I have unticked read only when I go into the folder properties. When I click apply it won't give me permission to do this, it says I need permission to apply read only to certain files and takes me back to the ticked folder. I have taken full ownership but still won't delete says I need permission of SYSTEM but when I check UAC I have administrator access but SYSTEM seems to have its own account which I don't/Can't access..SOO frustrating...spend last four hours googling it and tried everything but can't get control of SYSTEM to get the permission to delete the folder.
Please help..I am losing the will to live there is over 100gig there I want back..!!
I went through the same frustration as John and definitely no happy ending. I still have a big fat Windows.old folder smugly sitting there. It ignores everything from disk cleanup (no option to "clean up system files" anymore) to power admin commands and even though administrator has full control, that appears to be a lie. I'm sure MS in their finite wisdom thought it would protect users but I am down to 2GB of free disk space and getting a little desperate. Has anyone managed to delete windows.old in the production release version of W8? And if so, how? I may be able to do it if I create a linux boot disk on a flash drive but if there is an easier option that would be great.

Ok, I booted into safe mode but no change. I still can't delete windows.old. So I removed system ownership of the directory so that only the administrator account has full access to it. And ... same result: "you need trustedinstaller approval to delete these files." Beats me. later I'll download a copy of ubuntu and try to delete using that.
I used Brinks tutorial. l used option one [Disk-Cleanup] and it deleted the windows.old folder completely.
Although I no longer have an interior listing for "Previous Windows installation(s)" ;
there is still the option/radio button to click on "Clean up system files".
