Windows doesn't have a bad UI design, but there are better UI designs available now. For instance, if you are a Windows escapee, something like Zorin OS will feel even better. It's so well-designed that I migrated my family members to it after an old laptop became ineligible for Windows 11.
Zorin doesn't hate the Windows desktop design and embraces it with open arms. It looks polished, works nicely, and they have no qualms about it.
Zorin has perfected the seamless transition to Linux. It doesn't force you to learn the Linux way of doing things and keeps everything grounded. It has multiple editions, uses Ubuntu as its base, and promises long-term support.
