Seems a number of users are experiencing this particular error, The application was unable to start correctly (0xc0000018), after upgrading to Windows 10. I recently worked on one such computer for one of my clients.
This issue doesn’t appear to affect one application in particular but rather randomly affects different applications on different machines. On my client’s machine, he was receiving this error each time he tried to run VLC Media Player and/or open a command prompt. After spending some time tinkering with the system to no avail I finally resorted to searching the internet for a solution.
I came across several suggestions, including s registry hack, but the one that worked for me involved Malwarebytes Anti-Exploit. Seems this problem can occur after upgrading to Windows 10 from a Windows 7/8/8.1 system with Malwarebytes Anti-Exploit installed.
Sure enough, my client confirmed that he had Malwarebytes Anti-Exploit installed on the Windows 7 system he upgraded to Windows 10.
The solution was to uninstall Malwarebytes Anti-Exploit in Windows 10 and re-install. It’s a simple fix but only if you know which application is the culprit in the first place. So, if you’re experiencing similar issues after upgrading a system with Malwarebytes Anti-Exploit installed, this should fix it for you.
