Resolved windows updates stuck at 0% complete

machine is sony all-in-one desktop 64 version
Today first time I received a pop-up window from interactive message notification telling me that vcagent.exe (vaio care) is trying to send a message and that it's not compatible with windows. After doing a search online, I found posts about windows updates not downloading. I checked my windows updates and found 68 important updates available. I checked the installed updates and no updates have been installed since August of 2015. I get a 0% complete whether I try to install 1 or 68. my notification for win updates is "check for updates but let me choose whether to download and install them "
Based on other posts online I have tried stopping and starting win updates from cmd.exe and deleting the files in c/windows/softwaredistribution/download. None of that worked.

 

Thanks for the tips & tricks. When I have a year to spare, I'll start the process. However, I fixed it and don't really know which of these did the trick:
1) downloaded the system update rediness tool which got stuck running 2) changed the win update setting to "download updates but let me choose whether to install them" 3) ran sfc/scannow which found some corrupt files it couldn't fix, but the folder CBS log denied entry 4) rebooted
All 68 updates are now downloaded & installed.
