Frequently asked questions
What does TinyRDP actually do?
It gives each account its own Remote Desktop session on your PC, so every account runs on a fully separate desktop that keeps rendering even in the background. It automates the annoying parts around RDPWrap, the community multi-session enabler.
Will a Windows Update break it?
It can. RDPWrap depends on your exact Windows build. When that happens, just click Repair setup.
How many can I run?
Each session is a full desktop plus whatever you run inside it, so 2–5 on an average PC.
