Hello, Windows 11 doesn't officially support multisession in the same way as Windows Server does. Remote Desktop Services (RDS) with multisession capabilities is a feature typically associated with Windows Server editions. Windows 11 Home, for example, traditionally supports only one user session at a time. Windows 11 Enterprise multi-session, allows multiple concurrent interactive sessions, but this is limited to use in Azure Virtual Desktop scenarios.
Termsrv.dll is a critical system component, and modifying it can disrupt its expected behavior. This can lead to unexpected crashes, system hangs, or general instability.
Microsoft regularly releases updates and patches for system components, including termsrv.dll, to address discovered vulnerabilities. When you modify the file, you might unintentionally remove these security fixes, leaving your system open to known exploits.
I hope this helps! Please let me know if you need any further assistance.
