So, I was tinkering around w/my Dell Latitude E6440 laptop some weeks ago, let's say a month now and I mistakenly changed my permissions.
Now almost no programs work, not even Windows Explorer.
See the attachments for the messages I get...
"Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item."
and then...
"This file does not have an app associated with it for performing this action. Please install an app, if one is already installed, create an associated in the Default Apps Settings page."
This happened when I followed, or attempted to follow some online instructions on how to install Windows 7's "Windows Photo Viewer" on my Windows 10 machine.
I've already did the thing where you get the "hidden admin" account to show up in attemps to use that to update the other user's permissions and even that doesn't work
Almost no program works, except for Chrome, most gives a similar error message.
I'm hoping there's some bootable tool that I can use that'll fix this, I even tried all the Command Prompt solutions, nothing's worked.
Hence, I'm here, I really want to save files, and right now I can't even access them.
Looking forward to any feedback.
