    Question Anniversary Update messed up permissions. I no longer have Write access to disk

    This appears to have been caused by the Anniversary Update that Windows installed last night. Ever since then, my data drive D: has become read-only! Oddly enough, I can still make copies of folders but the copies don't contain any files. When I try to delete the folder, I get told I need to provide administrator access, and then permission from the owner. Of course, I am the owner, and also an administrator. So why can't I delete this??

    The advanced security settings for the folder in question reveal that both Administrators and me have Full Control. When I click on the "effective access" tab, it confirms that I have all permissions for this folder.

    I've tried logging off and on again, I've tried manually re-setting my account to an administrator. whoami /groups confirms this. I even tried using Elias Bachaalany's "Reset Files Permission" tool, all to no avail.

    I'm starting to run out of ideas... can anybody help? The owner of the root directory D:\ is SYSTEM, but that doesn't seem wrong. Would really appreciate a tip, in my years of Windows joy and suffering I have never seen anything like this. Thank you! And sorry for lack of screenshots, I had some but I'm not allowed to post them.

    I think your problem is something similar to this - Partition missing after installing Windows 10 Anniversary Update

    Pls post the image URLs without the http/www and I will edit them.

    Thanks for your reply HappyAndyK. This isn't quite my problem though - I can still see my partition, I just can't seem to write or delete any files from it!

    That tool looks useful, although I think it just automates setting ownership etc. which can already be done with Windows tools. Thanks for the link though, I'll check it out!
