This one is actually easy to solve.
• First open a command prompt as an adminstrator. Type the command "chkdsk c: /offlinescanandfix" and press enter. Answer "Y" to restart and check the hard drive for errors.
• When it comes back, Hold SHIFT then Restart the computer
• The computer will restart into troubleshooting mode
• Choose Start up troubleshooting ( the one that mentions Safe Mode)
• Let the computer restart to the "Safe Mode" Menu. Choose Option "5".
Now in the real "Safe Mode".
Open a command prompt as an administrator.
Type "Start ." (start space period), to open an explorer window.
Delete the contents (not the actual folders) of the following folders:
C:\Windows\SoftwareDistribution\Downloads
C:\Windows\SoftwareDistribution\DataStore\Datastore.edb (this is a file)
C:\Windows\Temp
C:\Users\<your user>\AppData\Local\Temp
Now restart the computer back into normal windows.
Now that you are in February going into March, download and install this rollup file (match your x64 or x86):

Run Windows Update after this, and all should be well.
