I started my Windows Server career around 2003R2, so can't comment on the peakness of 2K.

2008R2 snowballed it's own "revolution" when it introduced PowerShell 2.0, which was pivotal for many future things to come.

Out of the more modern ones, 2012R2 was "peak".

I would guess we will still see 2012R2 installations well into the future. Still running bits and pieces of critical infra, even if it has been EOLed long ago, but that's the way of the Server I guess. Can't wait for the 5000+ uptime day screenshots of ancient 2012R2's.

My guess is the next "long LTS" will be Win2025. Just because it's introducing the NTLMv2 deprecation path and working solutions to replace it.
