A number of problems after OS SSD was used on another computer

Hey everyone,

I removed the ssd which had the OS a couple of weeks ago but because some information needed to be accessed my sister attached a SATA to USB cable to the ssd and plugged it into her computer. She said that it asked permission to access the files and that she clicked yes.

I just came back today and installed my drive back into the computer but as soon as I logged in all I got was a black screen and the errors "taskhostw.exe application error" & "DeviceCensus.exe application error"

This happened a number of times and after I long pressed the power button to shut down I checked over all the cables to see if everything was ok. Once that was done windows did a scan and repair at the boot screen after which I could login and see my desktop but now my taskbar applications didn't show and the start button as well the things like volume control and notifications could not be clicked. I could open notepad files but when I tried to open an image file it would time out. I opened my recycle bin to see if I could and it did open but when I went to open my downloads folder it said that I don't have permission to open the folder.

I tried to restart but it just shows "Restarting" for a very long time which forced me to long press the power button and shut down. Now when I turn on the computer I can get up to the login screen which shows the date and time but when I click space so I can enter my password that screen never shows up, it just shows my login background with no other information.I've now been able to get into safe mode by using shift + restart but initially when running sfc/scannow I get "windows resource protection could not perform the requested operation" and when I run chkdsk I got that the file system is NTFS and "windows cannot run disk checking on this volume because it is write protected". The weird thing is that after a restart both sfc/scannow & chkdsk work fine and don't show any issues.

As of this post I can get past the login screen but like what I said initially, the desktop comes up but no pinned apps in taskbar, clicking on start button and notification area doesn't do anything, loading pictures which are on the desktop times out and I need to give permission to access folder such as downloads and videos and pictures.

Some help and advice would be really appreciated.

Thanks for reading.

We need to know what she did it sounds like she has changed permmisions on some things that are stopping it running. Under permission of folders does her name or strange user appear

She said that this is the only prompt that was given:

How can I check for permission changes?

As quick test can you set up a new admin user login with it and see if everything works so we know what needs fixing

I created a new username with admin privileges and after the welcome message it basically gave me a clean slate where everything works.

So the windows instance for the new user works fine it's just that my personal instance of the OS is messed up.
