Our company manages Windows Updates for around 100 computers from a WSUS server, and recently one of the Windows 7 Pro machines has been having trouble successfully installing updates. We will select only the important updates to install, install them, reboot the computer, then when the computer boots back up and goes to the "Configuring Windows" screen it sits at 32% for several minutes, before eventually saying "Reverting Changes." It usually takes upwards of an hour for it to finish that process and finally go back to the login screen, where Windows Update shows that all of the updates failed. We decided to turn off Auto Update and disregard installing the updates from the WSUS server, opting to try the "Check online for updates" option instead. When those updates showed up, and we attempted to install the important ones again, the same event occurred, and we waited upwards of an hour to log back in and see that they all failed. We noticed that running a repair on the .NET framework helped only those updates install normally, so those are no longer a concern. We had some luck for a while with doing only one update at a time, rebooting after each one, but we are left with about 5 updates that will still not install properly. We have run the System Readiness Tool, done SFC /scannow, used the SFC Fix tool, but this handful of updates still fails. Our CBS log folder can be found here:
Retrieve Components Hive
1. Navigate to C:\Windows\System32\Config and locate the COMPONENTS file.
2. Please copy this file to your desktop. Note: If you receive an error that this file is in-use, simply reboot your computer and try again. Note: If you find that you need to reboot and are unable to because this is a server then try Option#2 below.
3. Right-click on this file on your desktop and select Send To...Compressed (zipped) folder. This will create a file named COMPONENTS.ZIP on your desktop.
4. The file will likely be too large to upload here so please upload to SendSpace and just provide the link here.
Option#2 (only if you are unable to follow the previous instructions)
Go ahead and install this program and accept all the defaults. After the last install screen the program should open.
Click the New Backup button. Accept the defaults and simply click Start.
When it says Finished successfully, click the Close button.
This will bring you back to the main screen of the program. You will see one entry in this list with the date that you did it. Right-click on this line-item and select Explore Backup...
This will bring you into the folder where the backup was made. You should see a Users folder and a Windows folder along with a couple other files. Double-click on the Windows folder to open it. Then open the System32 folder and then config folder. You should see around 6 files in here, one of which is named COMPONENTS.
Copy the COMPONENTS file to your Desktop. If the COMPONENTS file does not exist, please fetch it instead from C:\Windows\System32\config\COMPONENTS.
Now right-click on the COMPONENTS file that is on your desktop and select Send to > Compressed (zipped) folder.
Then please upload the zip file (COMPONENTS.zip) to your favourite file sharing website (it will be too big to upload here). Examples of services to upload to are Filedropper or One Drive or SendSpace and then just provide the link in your reply.
You can close any open windows you have as well as the RegBak program now.
I did "Check online for updates" again and it found 7 important updates. I selected the updates, began the install, and it finished saying 5 successful and 2 failed. It told me I needed to restart the computer to finish installing, so I did. Then the same thing happened: the computer restarted, got to the Configuration screen, got stuck at 32%, began reverting changes, and now after multiple hours of waiting I was able to log back on to the computer. Windows Update shows that all updates failed, with the exception of the Malicious Software Removal Tool. So there are currently still 6 important updates.
Somehow there is a timeout error during the restart.
Right-click on FRST64.exe and select "Run as administrator". Note: Ensure that the Addition.txt check box is checked at the bottom of the form within the Optional Scan area.
Press the Scan button.
Please wait for the tool to finish. It will produce two logfiles called FRST.txt and Addition.txt in the same directory the tool is run from (which should be the desktop)
Post the log files FRST.txt and Addition.txt as attachment in your next reply.
