only goes up to 30 days.
you cant be serious that even if you delete it off onedrive its STILL somehow there forever. THATS IMPOSSIBLE.
I'LL HAVE TO CLOSE MY FUCKING MS ACCOUNT TO GET RID OF IT ALL
LMAO

I have formatted BOTH my laptop and my desktop.
I have gone into overdrive, deleted everything; put it to the recycle bin and deleted it from there too. Then I formatted both laptop+PC. AGAIN.
If that doesn't work idk what 2 do
