Windows 10 - Command prompt wont open

[chroniclard]

Strange issue, cmd.exe/command prompt wont stay open. It opens in a tiny window then instantly closes.

I added a new user account, logged in, worked fine. Switch back to mine and it wont work.

Cant find much googling, tried a few powershell commands to repair windows but it finds nothing wrong.

Anyone experienced this?

Nope, also makes the powershell windows tiny after typing commands!

No malware I can find.

Gave up and did a windows reset, now reinstalling all my stuff.
