Windows 11 VPN Speeds Drop After May Update KB5026372
Users on Windows 11 have reported slower VPN connections following the May update, specifically the KB5026372 release. The issue seems to emerge right after installation and a system restart, with VPN speed dropping to levels that make secure browsing or remote access impractical for many. Notably, the slowdown appears confined to wireless connections, while wired Ethernet setups continue to operate normally.
Microsoft has acknowledged the problem and is actively working on a fix. Affected users are advised to uninstall the May update temporarily until a patch is available. The guidance aims to restore typical VPN performance while Microsoft investigates the root cause and coordinates a resolution with VPN vendors and hardware manufacturers.
In related news, there is a note about Windows 10 support. Microsoft has indicated that support for Windows 10 version 21H2, released in October 2021, will end soon, pushing users toward Windows 10 version 22H2. The 22H2 release is described as the final major update for Windows 10, signaling a transition path toward newer Windows editions while enterprises and individuals assess compatibility and security needs.
These developments underscore the ongoing relationship between Windows updates and network performance. For IT teams and everyday users, the takeaway is to monitor updates, verify VPN compatibility, and plan upgrade paths that align with business continuity and security requirements. If the May update affects a specific VPN client, users should consult the vendor’s guidance, apply any available workarounds, and test network performance after updates or patches are released. The situation also highlights the importance of having a rollback plan, especially in environments reliant on secure, stable remote access.
Overall, users should stay informed through official Microsoft advisories and VPN provider notices. While a timely fix is being developed, avoiding nonessential updates on critical machines and maintaining a controlled update schedule can help minimize disruption. The broader context remains clear: operating system updates can impact network functionality, and coordinated testing between OS developers, device makers, and VPN vendors is essential for maintaining reliable connectivity across wireless and wired networks alike.
