My Surface Pro 3 upgraded automatically to the post-GUI restart button on its own. The remaining portion completed without difficulty as well. I did find 5 (!) obsoleted/orphaned packages in need of cleanup using "DISM ... /analyzecomponentstore" after this upgrade. But I'd been on vacation and hadn't been cleaning up lately, so I'm sure that's in part from prior package accumuluation.
Cheers!

Eleven forum recommends the site. They are official files from Microsoft.
But like I said, if you don't know what you are doing...
Install initially failed twice with 0x800f0990 error. Ran SFC and then DISM series (components were repairable), but still no go. Deleted KB5004296 install files from SoftwareDistribution\Download and tried again with a fresh download. Failure!
What an absolute mess trying to install this Cumulative has been.....five failures.....ran scannow.....ran dism.
Both supposedly repaired faulty files....Troubleshoot not available....WTF.
I had this issue also with 1110. The only thing left to do was update with ISO. I don't remember if I tried Shawn's WU repair tool which works quite well with certain issues.
Further to my earlier post have turned off and reset Bits.....cleared out most of Catroot 2.....again fail to update on Surface Pro 4.
Update to 1149 using ISO worked without any problems.
