This can be avoided by the simple expedient of a C drive backup made before the patch is installed. There are many free programs available, I have used TrueImage for at least 12 years with excellent results. Still use Ver 2010.
I have gone a step further by installing 3 Kingwin 3.5" Internal Tray-Less Hot Swap Racks on my desktop computer so that the three HDD can be swapped in the time it takes to re-boot. Cost under $20 ea, have used them for at least 7 years.
So to test a patch (or other equally dangerous excercises) a clone of the C drive is made, that clone is then used for the evaluation, reverting to to the original version can be done in minutes. My C drive is a SSD drive and kept very lean by using the 2 other removable drives to store videos, data etc.The C drive holds programs only.
So cloning the SSD C drive can be done in minutes, I do that every few weeks including weekly C drive backups to two external drives.
My SSD drives have a 3 year warranty, I was assured that they would last longer than that, even with the bi weekly cloning. And who cares with a clone and backups on hand. I paid less than half for the 250Gb SSD drives than for the 2 , 300Gb 10 000 RPM HDD I used before .
