One of the most common problem that many people are facing with the
Vista Windows Features is the dialog box came out empty or blank. You
can see “please wait” initially as it tries to make up a list but then
it totally blanks out. Microsoft of course is aware of this problem and
they’ve created a knowledge base 931712 to acknowledge the problem and
also provided 2 solutions to resolve this issue. First method is to run
command to scan all protected system files and replaces incorrect
versions with correct Microsoft versions. If that didn’t work, you’ll
have to do a System Restore. I also found another method in Google that
claims to fix it by running the following command “reg delete
HKLM\COMPONENTS /v StoreDirty”. I assure you that these solutions don’t
work. The only known solution that will fix the blank Windows Feature is
to reinstall Windows but then most manufacturer only provides recovery
disc and no installation disc. Don’t worry because I found a REAL fix
for the empty Windows Features problem without reinstalling Windows.
2. Once finished downloading, close all
running programs and run Windows6.0-KB947821-v4-x86.msu. Click OK to
install KB947821 update for Windows. You will see that it is as though
trying to install an update but actually it is trying to fix any
problems that it finds on the system in background using checksur.exe.
This will take a while, so you can go and have a cup of coffee.
3. When installation completed, click Close and restart your computer.
4.
Once Windows is booted up, try running Windows Features
(optionalfeatures.exe) and see if the list is loaded or not. IF not,
continue the next step.
5. Go to Windows\Logs\CBS\ and open
CheckSUR.log file with notepad. The following steps are going to be a little tricky because everyone gets different result.
6.
Take note of the part that says “Checking Package Manifests and
catalogs” in the CheckSUR.log file. If there are errors, you will see a
line with (f) followed by error code and path. If you see (fix), it
means the tool manage to fix that particular error.
As you can see, the fourth and fifth (f) lines are not fixed as it continues checking the next watchlist.
7.
Now you’ll need to manually delete the registry keys according to what
you see in the CheckSUR.log file. Run regedit and go to the following
location.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages\
As
an example, I see
Package_5_for_KB938979~31bf3856ad364e35~x86~~6.0.1.2.mum on my
CheckSUR.log file. So I need to look for the key in registry at the
location that I stated above and then delete it. There won’t be a .mum
extension on the registry. As long as the whole line matches without the
extension, you can delete it.
8. You will need to set full control permission before you can delete the corrupted registry key. Refer to
this article (http://www.raymond.cc/blog/full-control-permission-to-delete-or-edit-restricted-windows-registry/) on how to set the permission. After
deleting the corrupted registry, I am very sure your Windows Features
will start to show the list. The good thing about running System Update
Readiness Tool is it might have already fixed some problems which
probably you are not aware of. I have copied System Update Readiness
Tool to my flash drive because it is a potential utility to fix problems
in Vista.
