[SOLVED] How to clean Windows 10 OEM USB flash drive so I can use it for storage ?

Solution
They are write protected from the factory and removing that breaks the encryption and bricks the drive is what others have reported in the past.
Just buy yourself a regular USB flash drive ---- it'll be pre-formatted ready for use. Much less hassle than trying to work out how to deal with that Windows one & getting nowhere fast.

Tip: don't use a USB flash drive for long-term storage, they aren't reliable enough for that.
