TIL I learned that my old Technet Blog was indeed ported over to the docs.microsoft.com site–you can go find it here:
https://docs.microsoft.com/en-us/archive/blogs/undocumentedfeatures/
It’s old, doesn’t look great, but it’s neat to see that we did something with all the content from a preservation standpoint. I did move it all to this site as well, but in the off-chance that I missed something, the docs site might have it. 🙂
