I upgraded to windows 11 at the urging of security updates and such.

They really took away a bunch of features that make it difficult, for me as someone with a disability, to use the computer comfortably. I have made complaints about the problem and have basically received only "thank you for your feedback".

I have a loss of mobility in my hands and wrists as well as arthritis, so sometimes I have difficulty using the mouse and clicking around on the screen.

They the slide bars on the side of the file explorer and the web browsers (at least what I've noticed so far) so tiny and hard to click for me since I don't have as much as accuracy as normal users. I have to very carefully focus and make sure I click properly or I can't slide the bar. I attempted to resize this through some settings but it ends up making the web browser slide bars too big and barely makes a difference for the file explorer.

Then in addition to that, the design of the task bar at the bottom where it's centered in the screen is extremely frustrating for me to use. I am constantly misclicking items there as it was and then they added a bunch that I didn't want. I spent probably an hour resizing it and removing unnecessary items there.

And while it doesn't relate to my disability, I didn't like the little dots they used to indicate an open program, I preferred the outline. Which you can change but it wasn't very intuitive, I had to figure it out through googling!
