Something botched my Windows 7 VM on my lab while testing the December 2017 updates. 2017-12 Security Monthly Rollup update failed. I tried to troubleshoot for couple of days but headed no where. I decided to do repair using the Windows 7 with SP1 ISO. It complained that the Windows 7 VM was running with the latest update and the Windows7 ISO was not compatibile. I followed the following steps to slipstream Windows 7 with SP1 ISO to bring to the latest updates, create an ISO and repair the VM.

Creating fully patched Windows 7 SP1 image by Slipstreaming in with Convience Rollup and Quality Rollup

1. Window 7 with SP1 installation ISO
