What limitation do non-server versions of Windows have regarding remote desktop, and how can I work around it?

Non-server Windows (like Windows 7, 8, 10) by default allow only one user to be logged in remotely; if a different user attempts to connect, it prompts to disconnect the existing session. To bypass this, you can use methods like mimikatz memory patching, permanently modifying `termsrv.dll`, or using the rdpwrap tool. These techniques are commonly used in penetration testing to maintain access without disrupting existing sessions.
