Windows 10: Reformatting my laptop or deleting files without being deleted in my other laptop. I use...

I would like to delete files on my old laptop locally but still remain on my other laptop. It happened before that whenever I deleted a file locally, it also got deleted on my other laptop. I use onedrive. How can I solve this problem? I am also planning on reformatting my old laptop but all the files that are synced on onedrive might be deleted on my other laptop too as it happened before when I tried to delete a file from this laptop. Please help.

Just broke work laptop screen... want to delete history/save pw

Just broke by work laptops screen.
I want to delete my browser history and save passwords but I cannot use the screen at all or the VGA out put. Can this be done from deleting files on the hard drive?

No not porn history... Save passwords and logins to sites I would rather not give random IT guys access to... facebook, my payroll, etc...

Any one have an idea?
