Issue: How to fix error code 0xc000007b on Windows 10?
Hello. Could you please help me to fix the 0XC000007B error? The message keeps popping up when I try to run a game or application. It often shows a full message ” Application unable to start correctly” or just the error code. I’m using Windows 10 V1709. Thanks in advance!
