Explain Windows executor versions
This has also been frustrating to me. I would love to see a pinned version number for the windows executors so that I don't have builds suddenly failing for changes to the executor image. The list of preinstalled software on the hello world page is also not correct (for example, it says python 3.9 is installed but it is actually 3.7). The latest change to the 'stable' version of the windows server image also broke my ability to SSH into the build, which made it much more difficult to troubleshoot (I was able to rerun the build with SSH and verify my credentials were accepted on the circleci server, however, the powershell session would just hang and my only escape was to close the session completely).
