I tried to modify W7 Ultimate. Everything works okay and I receive no errors in Events Viewer, however, Windows version field under Control Panel/System is... blank. What could be causing this? Thanks in advance.

The problem:

Same goes for 'msinfo32': "OS Name" is blank, and dxdiag: "Operating System: n/a 64-bit (6.1, build 7601)"

I guess it's about a missing registry record. How can i fix the problem? Windows works as usual but the missing piece of info is disturbing.

Okay, I fixed the problem. The issue was caused by two missing files: %SystemRoot%\Branding\BaseBrd\basebrd.dll and %SystemRoot%\Branding\ShellBrd\shellbrd.dll. I mounted an image of w7 ultimate and copied the files.

Now the question is: what package is responsible? BUC Namespace perhaps?
