Hi. My name is Martin, and I used to work along with Intuit on their U.S. Quickbooks Desktop technical support team around the time when Windows 10 was fairly new. Each time a new version of Windows comes out, a lot of software, not just Quickbooks, have problems because they are designed for certain systems. Intuit may be working hard right now to get desktop to work with Windows 11 just like they did with Windows 10. I would check the System Requirements on the website to see if they have updated them with Windows 11. Until then, using it with Windows 10 is your best bet.
