Windows 10: Can't delete windows.old folder
It should be run as administrator.
the BEST way of reverting to a previous version of Windows is the following:
1) BEFORE upgrade image your Windows partition - don't forget the system reserved one as well --something like Free Macrium works fine.
2) After upgrade if you want to revert simply restore your backup image --incidentally before reverting take another backup of your updated windows as you might want to use it again without the re-install / upgrade process having to be re-run.
Normally the windows.old file can be deleted in the Disk cleanup --can't say it asked to be run as admin.
Another foolproof method is to boot say a Linux Mint system from a USB stick and use the file manager to delete the windows file. File manager in Linux is usually called something like Dolphin, Nautilus, Midnight commander etc --it's pretty obvious which one. Linux Mint is reasonably like Windows for doing this type of stuff.
I'm running a Linux VM - same principle applies

Windows10Upgrade folder is dated Aug 3. Please let us know if it's still there after Aug 13. I know that previous article mentions 10 days but maybe it will take a couple of more days. I'd like to know what to expect when my Win10 Anniversary Upgrade happens.
1. The culprits are probably the system devices shown in the attachment. Disable the Broadcom device, uninstall (don't delete) the two Intel IO Controllers, and run Disk Cleanup. That should remove the Windows.old folder.
The Broadcom device can then be re-enabled, and the Intel Controllers restored by doing a scan for hardware changes in Device Manager.
2. Windows10Upgrade folder can be removed by uninstalling Windows 10 Update Assistant .
3. Should this procedure fail, you'll need to take ownership of the respective folders.
An easy way to delete the residual files left in windows.old is to boot from a linux drive or a winpe drive (eg a Macrium Reflect recovery drive).
I'm in the Windows Insider program and have updated Windows 10 several times now. Each time, creating a windows.old folder. Do I need to keep these, and if not, what's the best way of deleting them? This is probably a silly question, but better...
So I followed these steps:
I opened my search box.
In the search box, type Admin, I right clicked Disk Cleanup and selected run as Administrator.
In the Disk Cleanup dialog, I clicked Clean up...
After doing an In-place Reinstall of WIndows 10 X64 to fix update problems. I ran the Clean Windows Files Program to Delete all 'Old' Windows Folders & files. All seemed to go well until I looked at C:\ dribve and see that Windows.old still exists....
I had problems with Windows and did a in-place upgrade which took C:\Windows.old and changed it to C:\Windows.old(1) while creating a new C:\Windows.old. Disk Cleanup got rid of C:\Windows.old but how do I get rid of C:\Windows.old(1)?
Can I delete Windows.old folder ? and is it any important file inside that folder ?
and where can I find my device manager ?
