Roles Error and Features Error in Window Server Manager

Roles Error and Features Error in Window Server Manager - can be a real pain.

You can do anything to fix it and it relates to Windows update getting its knickers in a knot. 

 

In some cases Ive found that installing Hotfix for Windows (KB947821) sometimes helps.  Its the only thing Ive found that avoids a complete OS reinstall.

 

1. Download the right KB for your OS http://support.microsoft.com/?kbid=947821#method2

5. If not then check corrupt information in the files. Here are some samples at the bottom of this post on how to manually fix them:
