Some people actually even also seem to underrate the physical and conscious effects of such changes. The Windows 7 style choice for the Start Menu of Open-Shell adds multiple features that can, and do have a measurable impact on the amount of physical work effort a user has to go through to accomplish certain tasks in various many situations depending on worflow. A lot of people are very conscious of the fact that a persistent lack of these features is what physically impairs productivity, not just because the user had grown accustomed to features having been crippled or gone missing altogether, but simply because the user has to depend on a highy repetitiveness character of some certain UI actions. The repetitiveness factor amplifies those kinds of effects in many different ways.
I started using Classic Shell when it was still an early beta release. On Windows 7 x64 Ultimate. Back in the day, tons of people were ready to wage war against Microsoft because Windows Explorer (nowadays called File Explorer) had breadcrumbs instead of the up arrow button (the one that let you navigate up a level in your folder tree structure on Windows XP). Microsoft later decided to bring back the up arrow button. So, Classic Shell was very much necessary on Windows 7. More than you know.
James,
No, they're on separate partitions so there's no way Open Shell could see the registry entry in the other operating system.
You can't blame Windows 11 for being a truthful OS.
You can use them both still............
