Multiple RDP (Remote Desktop) sessions in Windows 11

To enable concurrent Remote Desktop (RDP) sessions in Windows 11 , you need to make a small change to termsrv.dll file. The file is located in C:\ Windows \System32 folder. Before modifying termsrv.dll for the first time, you need to take ownership and assign yourself full access permissions. You also need to stop the Remote Desktop service (TermService).

DLL files can be modified using any HEX Editor (for example Tiny Hexer).
