The is a small utility or manual hex-editing process that modifies specific bytes inside termsrv.dll . By changing a few hexadecimal values, the patch disables the session limit enforcement, allowing an unlimited number of parallel RDP sessions.
The patch locates and changes a conditional jump instruction ( JNZ , JE ) to an unconditional jump ( JMP ) or alters the comparison value (e.g., changing a cmp eax, 2 to cmp eax, 9999 ). Specifically, for Server 2012 R2, the known patch targets the following hex pattern:
8B 81 D8 00 00 00 83 F8 02 7D ... or B8 00 00 00 00 90 90 ...
