Cannot confirm since the person decided to get used to the 10 menu and navigation. But here are some tips.
I learned from a Norton tech that MS continually makes drastic internal changes to the OS for reasons we will never know. These may break some programs and drivers, like the recent "old" nVidia video drivers, which rendered the machine unusable. Additionally, the "Feature Updates" may be the most problematic for program writers, since not everyone installs them. Same may go for the "Builds".
The machine in question was using Build 19042.746 and Feature Update 20H2.
Thank you for your rapid response.
