Bypass Microsoft Software WGA Checks

I published a guide some days ago that explained how you can download software from Microsoft's Download Center without having to pass Windows Genuine Advantage (WGA) checks. Several users who tried the method ran into issues after successfully downloading the programs to their systems as a second check was performed during installation of said programs on the local system.

The problem here was that the software would not install if the check during installation failed, and there was seemingly no option to prevent the check from being executed during installation of the application on the local system.

You can use a program like MuBlinder to bypass the checks on the local system as well.

Update: The program MuBlinder has not been updated since 2010, which is an indication that it may not be working anymore with newer or updated versions of the Windows operating system. While you can still download the latest version of the program from the project homepage, it is likely that you can't use it anymore for the purpose.

Some users however are reporting that MuBlinder is still working properly. If you are desperate you could try it out to see if it resolves the issues that you are facing with the downloads from Microsoft. If you are receiving error messages, I suggest you post at the official forum thread to have them resolved.

We all know that WGA checks sometimes identify legit systems as non-genuine and users who experience this issue face the same limitations that users face who are running a non-genuine copy of Windows: they can't download some software from Microsoft even though they should be able to. While it is certainly possible to contact Microsoft Support to resolve the issue, a much faster and less stressful solution is the use of aforementioned program.

Please note that you do need the Microsoft .Net Framework to run the application. According to the author's homepage, you need at least the .Net Framework 2.0 to run it.

Update: The program is no longer available. It seems to have been pulled.
