Windows 10: CMD becomes smaller and instantly closes: Can't use CMD

Hello. I've been having trouble using the command prompt recently. Whenever I open it, by any means, it quickly shrinks and closes, without me being able to use it.

I've already tried opening it as administrator, and executing it with the "/k" suffix.

Extra info 1: When I run the Power Shell (admin), and type in "cmd", the Power Shell version of the CMD is shrunk to the same smaller size. However, it doesn't close. So this means, yes, I can run the cmd indirectly through the Power Shell, but that is not my intention. My intention is to fix the cmd.

Extra info 2: When I change the console dimensions, it only affects the "pre-shrink" dimensions. The shrunk dimensions remain the same, always.

Extra info 3: When I run a c++ console application, it works all right. However, if I use any "system" functions (cls, pause, title, etc...), the console shrinks at the moment of it's execution and the program terminates. This makes me believe the problem is not with the console, but somewhere both cmd and system functions access... By the way, I noticed the problem for the first time while working with cpp applications, and this is the issue that annoys me the most.

These screenshots illustrate what happens when I try oppening the cmd via normal means, for example:



1: The normal-sized cmd flashes for a very brief moment (it was hard capturing it).
This momentary window does get affected by edits in the console screen size

2: It imediately shrinks to this tiny window. This one lasts for a split second.

3: It quickly closes.


Please, help me fix my cmd. This issue is annoying me a lot and has been rendering useless many of my applications wich rely on the "system".

CMD not working.


My CMD is not opening. Everything else seems perfect and powershell works. Anyone know how to repair it? I tried the restore health line in powershell, it didn't work.

EDIT: I opened just now and it said something about sound mixer, sat for a min and closed out. Then trying to open it again and instantly closes.....
