Windows 11 VPN Woes: When Updates Play Hide and Seek with Your Network
Windows Subsystem for Linux users, brace for impact! Microsoft reports that the latest Windows 11 security updates are causing VPN networking failures. So if you’re seeing “No route to host” errors, it’s not you, it’s them. Microsoft is on the case, but no timeline for a fix yet. Stay tuned!

Hot Take:
It seems Microsoft’s latest Windows 11 update is playing a frustrating game of “Hide and Seek” with VPN connections. Who knew a security update would have a side gig as a VPN kill switch? Maybe it’s time Microsoft hires a professional matchmaker for its networking protocols!
