Win8.1 Update 1 install was not an easy task. (Win8.1 Pro 64bit)
KB2919355 Failed to install : 09Apr, 11Apr, 11Apr, 12Apr, 12Apr, 13Apr, 16Apr, 17Apr; succeeded: 17Apr.
After the first three failures I did an online search and found the following information:
According to a posting I found, when Windows 8.1 Update first fails to install, the original patch does not clean all leftovers, so all your attempts to manually deploy the new release will obviously fail as well. Andrew B recommends users follow the next steps and then try to install Windows 8.1 Update manually.
1. Launch Command Prompt with administrator privileges
2. Run the following command: dism /online /remove-package /packagename:Package_for_KB2919355~31bf3856ad364e35~amd64~~6.3.1.14
3. When step 2 is completed, run this command: dism /online /cleanup-image /startcomponentcleanup
4. Try to install Windows 8.1 Update manually
I followed these steps and tried both an online and offline installation a couple of times - without success. More searching resulted in more information:
1. Dism /Online /Cleanup-Image /RestoreHealth
2. SFC /scannow
The next attempt at installing Update 1 worked. I then checked the CBS.log file in the \Windows\Logs\CBS folder and found numerous comments that 'SFC /scannow' found many missing or corrupted files and took action to replace them. I was surprised that many of the 'new' files were images and were in the \Windows\Web\Wallpaper\Themes1 or \Themes2 folders.
I had previously deleted all images I did not want as wallpaper - there was no option to unstall themes using Control Panel > Programs and Features > Turn Windows features on and off.
So, it appears that Win8.1 Update 1 expects to find 'everything' that was part of the initial/original installation still on the computer even though I "Took Ownership" of the original images and folders and deleted them. SFC /scannow may have repaired/installed other files but that information was eliminated with the successful install.
