One drive has messed up my whole PC. How do I get my files back on my PC, and switch off one drive forever. (Please dont answer a question I did not ask)?

Microsoft needs to fix this issue, Microsoft may call it a backup feature, but it is not.

Microsoft assumed we wanted to backup our desktop (and other stuff), without ever asking me. When I go into the OD app and unselected the option, OD did not know how to undo it. What it does instead is to remove the files on the Desktop and now the only copies are in OD. OD should delete the OD copy (because I unselected the option) and leave my Desktop copy alone.

I too wish Microsoft would stop calling OneDrive a backup feature. I do not trust OneDrive to backup my PC. It does wonky things on occasion. On my primary PC OneDrive is set to “Always keep on this device“ so that the files are also stored on my PC as well in OneDrive. & I use “File History” to backup my primary PC to a secondary drive, so that I have a backup of OneDrive on a physical drive in my PC. That has already saved me once.

On my other PCs I have set OneDrive to “Online-only”,  so that I do not store any files on those PCs. In other words, I cannot open them without an internet connection. I’ve seen instances where multiple PCs in the “Always keep on this device“ state have overwritten each other. Hopefully, placing the other PCs in the “Online-only” state will keep that from happening.

OneDrive sure is handy, lot of moving parts though.

Hate One Drive, when I tried to keep on my computer, or pause, it will not let me mark the documents I don't want backed up, says One drive is running and can't do that at this time. when I finally found where to un sync, my documents folder and files are so messed up and/or missing, there will be a few files then another document folder, that has a few files/folders, then another document folder and another one drive. Probably now have t least 7 document folders and still cannot find all my files. I did not turn sync on, never wanted my stuff in the cloud. Total mess.

It would have been a great reply had there just Been the Option to "Keep files on this Drive". There are 36k files that I NEVER gave permission to be put in some cloud.

I completely agree with you. It was horrifying when setting up my new laptop to see my files going into a cloud. All MS said was "All your files, conversations, phone info, everything in your life basically will be stored in OUR cloud!" And I didn't know how to stop it.

And now after seeing instructions on how to get them back there still is not an option to "Keep all file on this computer" as the directions said.
