Stephen's response below is correct and should be the official position for any beta release of the operating system.

I have some pc's that are part of the Windows inside scheme and accordingly upgraded to Win 11 today.

As much as 4 hours testing is reliable!!!😊:

1. Windows apps. Compile, ran without errors. Printing (hp and pdf drivers) have run as expected.

2. Web Order sample app, compiles and ran without errors. Printing works perfectly.

3. 4K display for studio appears to behave the same.

So far so good but a week of testing will result in a more reliable position.

I like the look and feel of Win 11. No doubt there will be the normal "how dare MS change what I am familiar with" complainers.
