Microsoft is looking into slow VPN speed problems in Windows 11 caused by recent updates
The curse of the problematic Windows update may have struck again. Some users who installed the KB5025305 preview update or the KB5026372 update for Windows 11 are complaining about a significant slowdown in VPN speeds.
Microsoft says that it is looking into speed issues with L2TP/IPsec VPN connections in Windows 11. The company is yet to provide a fix, but there is a less than ideal workaround available in the meantime.
