Microsoft's latest Windows 11 update, KB5036893, released in April, has disrupted the functionality of some VPN apps that rely on TPM-backed certificates. Users affected by this issue are unable to access necessary certificates for VPN connections using the Extensible Authentication Protocol. Microsoft is aware of the problem and is currently working on a fix. In the meantime, users experiencing this issue can uninstall the update to revert to a previous version of Windows 11, which involves navigating through the Settings menu to the Update History section and selecting "Uninstall Updates."
