4.3.20 compatability with patched uxtheme.dll

Post by Weboh »

So, I was having problems running VirtualBox for the longest time. But then I heard somewhere on here that a patched uxtheme.dll might be causing the problem. Sure enough, it was. I tried just copying the unpatched file into VirtualBox's directory, but no luck. It won't work at all with that file patched. I really like using third-party themes, so I want to keep that file patched if at all possible. Are there plans for a future update that removes VirtualBox's dependency on the unpatched file (to be like it was before)?

I'm sure they're working on it. But if you really need to get going, go back to 4.3.12. That's the last version that didn't have the security-hardening system in it, thus no incompatibilities with themes. 4.3.12 is able to run Windows 8.1, too.

The security hole seems to be that malware on the host can use Virtualbox processes to get higher privileges than the malware could normally get, thus causing greater problems. To at least filter said security hole, if not plug it, with 4.3.12, just keep malware off your host.
