It would be nice if there was an 'upgrade to W11 adviser' utility as there was an 'upgrade to W10 adviser' utility which (also) advised on the app compatibility issue.
Perhaps/hopefully such utility will become available by EOL of W10, it would be very useful for would-be-upgraders to W11. Would also be useful for MS for defending Windows' market share, I would think.
In reality, there are very few apps that if compatible with Windows 10 that would not be compatible with Windows 11. There was a need for it between Windows 7 and Window 10 as a lot of changes.
In the end, who would create such a utility. People never consider who would create it or pay for it, or maintain it.
Unlike Apple which is a pretty closed ecosystem, Windows is a more open system (virtually infinite range of hardware and software).
It is only the vendor of packages that can say if packages are W11 compatible, and all major vendors e.g. Acrobat will have done that.
So who would develop a list and maintain it?
Most people will want Microsoft to do this but they can only do something basic i.e. uninstall any app they are advised by vendor that is not Windows 11 compatible.
Many people got upset when Windows 10 did this BUT they only did it when advised by software vendor. So MS were blamed for the action but they had no real option as they would only get blamed if pc crashed, data got lost etc through no fault of their own.
In reality, the main issue was people had old versions of software and all they had to do was update to latest version in most cases.
The only ones that tended to be problematic were the free utility type (many of which had not changed for years). Even then, some people reinstalled same version and it worked fine anyway.
Re. EOL - Windows 10 is not EOL for several years yet. By then most will have upgraded anyway.
From a user viewpoint, the safest approach is to make an image backup of existing Windows 10 installation as it works now, then update all 3rd party packages to latest version, upgrade to Windows 11 and try it.
I just do not see that MS should waste resources on an aspect that is not really their problem. No matter what people think, MS do not have infinite resources.
