    Permissions changed & Attempt at changing windows theme failed


    Hi, I messed up big time. I'm currently typing this from a USB stick that has windows installed on it allowing me to run It when I go to the BIOS. I can't provide my actual windows version because this one has an outdated version of windows, but if you want the usb version it's 1909 (OS Build 18363.418). My actual OS I don't know, I do know it's one of the insiders builds.

    So my mistake was first, I tried to install a custom theme for control panel, task manager, ect. The ones the official dark theme doesn't cover. So first I messed with some files in the Resources/Theme folder I think, I can't remember the directory, it was in C:/Windows/ though. They were called "aero" files and I moved an entire folder into the one before it and renamed the file type of one to "bak" and In order to that I had to get past TrustedInstaller, ok fine, so I did that eventually.

    Now here comes the good part, I had the "brightest" idea and said to myself "Why not just make it so the entire OS is owned by my user account and not TrustedInstaller?" so I went to the C drive, did the stuff to change it, but it errored only a few seconds into changing it and said it couldn't be completed and stuff would go wrong if all the files aren't changed, tried it a few more times and eventually got scared and just backed out, big mistake. Then, I made a restore point, (wow good place to do it right?) and I installed UltraUXThemePatcher, then restarted. Now the actual OS, when it boots up just shows a black screen with the mouse you would see in safe mode, sometimes the screen glitches too. And booting into safe mode does the same thing too. So everything is completely messed up and I don't know what to do anymore. I completely messed up my pc because I couldn't suppress my hunger for those good looking themes. Please help, I looked online for what I could do to change permissions back to default blah blah blah, but it seems to be hard when you're on a USB drive.

    Edit: Forgot to mention, for a moment I went into a blue screen loop (for two restarts I think), with the error code: PAGE_FAULT_IN_NONPAGED_AREA and went wrong was: klkbdflt.sys

    Welcome to TenForums!

    I have a few possible suggestions:

    1) How current are your backups? (You do have backups, right? ). If very current, restore from a backup.

    2) Temporarily disconnect the current HD, insert a new HD and install Windows onto it. Reconnect the current Windows HD as a secondary HD and pull off any data that you need to keep.

    3) Connect the Windows HD to another system as a secondary disk and pull of any data that you need to keep. Then, reinstall Windows to this HD and copy back the saved data.

    What do you mean by backups? If they're actual file backups, no. But if they're system restore points, yes. But the one I made I tried to restore and it didn't work and I don't have anymore.

    What does HD mean? I get what you're saying, but I'm just confused as to what that means. It's very confusing.

    I looked at that tutorial and it would be great if I could do it because it's pretty easy by the looks of it. But I can't do it because I can't boot into my SSD, when I do it'll just show a black screen and no buttons to make things appear works (ctrl+alt+del), and all I can see is the default mouse. Right now, I'm running windows off of a USB drive, every time I boot the pc I spam F12 and choose the USB drive to boot into it. So if I tried that it'd just apply the fixes to my USB stick not my actual OS right? Unless you can choose that.

    Ok, it's fixed. I backed up all my files and reinstalled windows. Thanks for your help.
