How to Fix Error Code 0xc000007b on Windows 10

Error Code 0xc000007b is a common Windows problem that got worse after the Windows 10 Anniversary update came out. But these kinds of problems tend to last for a long time. People can’t open certain apps, and it usually happens right after a patch or feature update.
