I have just performed a clean install of Windows 10 Pro x64 20H2 (build 19042.631) on my new PC. I used an installation image which I created on a USB flash drive using the MCT.
After installation I clicked Control Panel (All Control Panel Items) > System to check the activation status but, to my surprise, I discovered that the activation status is no longer listed on that page. It was listed there in version 2004. In fact, after some investigation, this page appears to be the same page that you get to by clicking Settings > System > About. Can anyone confirm that all this is as it should be in 20H2?
So, other than by running the slmgr command, it now appears that the only way of checking the activation status is by clicking Settings > Update & Security > Activation.
