I have the same problem with this update along with the other two updates n 2/7/2020.
The Windows Explorer will take forever to do anything when I open up it. I have to use the Task Manager to RESTART it. Then my systems starts get into memory leak and I am not able to open up any WORD document --- all of the graphics disappears and I am not able to even open up TEXT FILES.
I have been having issues with WINDOWS 10 PRO since I got this laptop when WORD is open and I have a large file, it says I am not able to save because it is out of memory. But I have 16 GB RAM and it shows I have enough memory. What I am thinking Word has it's own memory space and it there is NO MALLOC to recover the memory cache. Very poor design on Windows. But it happened less often, but with this update it was worst. I did not even have to open any WORD document, I get the memory leak and the GRAPHICS disappears. I HATE WINDOW 10 - very poor and NOT a Multi-Tasking Operating system at all.
I also notice when I copy things to an external disk and I if I have done a lot of it. I get memory leaks again. There are major bugs with the Windows Explorer for sure.
Doesn't anyone test this at all before it is released? For the last 19 years I worked in Software QA Engineering for CyberSecurity, Cloud and other enterprise software and we have extensive performance testing for stress and users.
I really do not like to be forced to do updates on dangerous bug updates, I no longer have a choice. I will now block all updates for now on. But I least I have the driver are up to date.
I wish I had Windows 7 still and Windows XP were the most stable.
