Vista and 7’s Windows Features list is actually pretty much the same as Add/Remove Windows Component in Windows XP. You can also run Windows Features by typing “optionalfeatures” at the run dialog or command prompt.
One of the most common problems that many people are facing with the Windows Features dialog is the window comes out empty or blank and the features list doesn’t appear. You can see “please wait” initially as it tries to make up a list but then it totally blanks out. Microsoft of course is well aware of this problem and they’ve created a knowledge base article 9. The first method is to run the sfc /scannow command to scan all protected system files and replace incorrect versions with the correct Microsoft versions. If that didn’t work, they recommend a System Restore. We can assure you that all these above solutions don’t work.

The reason why SFC or System Restore don’t work is they don’t restore anything in the Packages folder and therefore miss the problem altogether.

SUR. log file with notepad. The following steps are possibly going to be a little tricky because everyone gets different results in the log file. Take note of the section that says “Checking Package Manifests and catalogs” in the Check. SUR. log file. If there are errors, you will see a line starting with (f) followed by an error code and path. If you see (fix) on the next line below the (f), it means the tool managed to fix that particular error.
