Windows 10: OneDrive Will Not Sync. Cannot Uninstall Corrupt Version. Cannot Change Settings.

Ok. I have tried to unistall OneDrive. Can't do it. It won't disappear. Can't get rid of it. Have tried uninstall, several restarts, nothing. So when I install the new version, it's just the same problems. Can't change settings. Nothing will sync. This happened after the damned forced updates yesterday - so that could be the cause. But I really need some help getting this back up and running.

Windows 10 - OneDrive

Right click on the app and one of the properties has an option to not automatically start it. Uncheck, restart the computer, and it should stop. If you want to go another step further, find the OneDrive app in the start menu, right click on it and uninstall.

If that is still insufficient, there is a batch uninstaller for OneDrive available online. I can copy the code here if you need it.

 

Add or Remove OneDrive from Navigation Pane in Windows 10  

I see you already checked the Reg keys, but try the steps again in the tutorial.....first removing (set to 0) all, signing off and back on. Set to 1, all, and sign off and back on.

 

OneDrive Sync Issue

Honestly, I don't understand why you haven't already tried to boot with WinPE or other live disk and manually remove the file? This example using Macrium WinPE boot disk, download Macrium Free and let it create a boot disk for you. Option to create one is shown automatically when you launch Macrium first time:

1. Switch to C: drive
   
2. Change the working folder to your OneDrive folder
   
3. Check that the file has no Read Only (r) and System (s) attributes set. As the file name in your case is quite long, you don't have to type the full name. Use the *.* wildcard to replace any number of characters in file name and any extension, in your case command attrib .849C*.* should be enough
   
4. If r and / or s attributes are shown for the file, remove them with command attrib .849C*.* -r -s
   
5. Check that attributes r & s are removed
   
6. Delete the file with del .849C*.*

(Steps 3 & 5 not necessary; step 3 because removing attributes as in step 4 removes them if set but does no harm if not set, and step 5 because the attrib command works for 100% sure if no error messages are given.)

The file should be removed now. You can test with command dir .849C*.*, it should not be shown anymore.
