On the non-Windows Server side of the fence is the Windows 11 preview build 22538, which features voice access updates along with loads of fixes.

As for non-Insider updates to Windows, Microsoft recently remedied an issue January's Patch Tuesday caused wherein VPN connections were crippled. The initial cumulative updates, while packed full of useful security fixes that addressed various vulnerabilities throughout Windows, also borked some users' VPN capabilities, leaving those on SonicWall, WatchGuard, and Cisco Meraki (potentially in addition to others) in a tight spot. That's all in the rearview mirror now, meaning Windows, in all its various forms, is once again at peace. Now go get those Windows Server preview build ISOs.
