Windows 11 released – UPDATED – what does it mean for the viewer ?

Microsoft has released Windows 11 on October 5, 2021, with features but more important requirements that has consequences for both OpenSim viewer users and developers.

Unfortunately I don't own any hardware that is capable of running Windows 11, so I have no ability to test if the Dayturn viewer will even run.
Also Microsoft has made restrictions to virtual machines running Windows 11, so even those won't pass the requirements tests for installing and running it.

I am not sure if this means the end of development of the Windows version of the Dayturn viewer, because it is highly unlikely I will buy a new machine for the purpose of running Windows 11.

Meanwhile, for those of you who can run or want to run Windows 11, there is an excellent review on arstechnica. But also this leaves many questions unanswered.

I found a recipe for installing Windows 11 on an unsupported system, and it worked to get Windows 11 up and running with TPM support in a VMware Fusion virtual machine. The procedure upgraded a vm with Windows 10 already installed.

The above vm also had the latest version of the Dayturn viewer installed, and it seems to be running fine, so that is good news.

I also tested the Secondlife viewer, and it installed and ran fine.

I was also able to install updates via Windows update, but any major updates are likely to break the installation and you'd have to go through something similar to the installation procedure to get it back running. YMMV, so proceed with caution on a system you can afford to lose.
