I messed with User permissions..

    I messed with User permissions..


    While trying to delete the old windows files after an upgrade it kept denying deletion because TrustedInstaller wouldn't allow it so I tried to change ownership from TrustedInstaller to to administrators group and things went down hill from here. apparently a 2nd group of administrators was created and by mistake I deleted the old (original) one, there is also a user called 'CREATOR OWNER' which I deleted too but shows up somehow on other files. It won't allow me to delete these files and asks for permissions from administrators which apparently now is a separate group.

    How do I fix this cluster&$^&#? thanks.

    For more illustration, this is what it looks like:

    Hello and welcome to TenForums :)

    If you have set up system restore points the simplest way to fix this is to revert back to a earlier point in time.

    To delete Windows.old you have to run disk clean when it's run then select system files and it will run again and include the folder once deleted you can't role back to old windows

    Ok, so I did this and there is still 1 GB that wont be deleted even with disk cleanup. It's important for me to get every possible GB because the space in C isn't very big at all so any advice on how to finally get rid of the old windows is appreciated.

    Atleast can some one confirm the remnants of the old Windows will be deleted on their own in a month? this trusted installer is really annoying I have to say...

    Make a bootable USB flash drive or DVD of Kyki's recovery drive and use file explorer when booted into it to delete the files:
