[SOLVED] [7SP1HP x64] kb4075211,kb4074598,kb4091290: error 80070020 reverting and fail install

Go ahead and restore all the files from the 2/7/18 backup to their original locations in c:\windows\system32\DriverStore . So they should restore and overwrite the files within this directory. Let me know when complete.
 
I wasn't able to restore the repository but all files in it were older. Temp had a directory with yesterdays date but all files were older. I have the entire driverstore on my desktop
 
Do you have your Windows 7 media so we can do a repair install? It shouldn't affect your data or programs so don't worry about that.
 
I finished the repair install and updated 32 drivers. I then updated 250 patches and the only error so far was for kb982670 which is an update for net client. I have hidden it and everything seems OK. Microsoft does not even offer kb4074598 through the regular download. Do you still want me to try the install of the standalone
 
Those updates appeared again when I took it out of clean boot. I will still do a bit of testing and will let you know the outcome. Please do NOT close this yet
 
kb4074598,kb4076492, and kb4055532 installed successfully after the install. The only failure was kb982670. Microsoft had offered kb4074598 but it was late in appearing.
