Does Remio need Windows Pro to accept the connection?
No. Remio installs its own host on the PC - Windows 10 or 11 Home, Pro, and Enterprise all work without changes. The Windows RDP server, which is Pro-only, is never used.
Do I need a Microsoft account to pair?
No. Pairing uses a QR code or a Device ID and PIN - get a new PIN anytime from the host. No Microsoft account, no Remio account, no email.
Does the Magic Keyboard's trackpad actually control Windows like a mouse?
Yes. The trackpad's pointer movement, inertial scroll, and two-finger secondary click all forward as native Windows input - the same trackpad behavior you already know, just driving a Windows cursor instead of iPadOS.
Does Apple Pencil work for precise work in Windows apps?
As a very precise pointer, yes - the Pencil's fine tip makes it easy to hit small controls and place a text cursor exactly in dense Windows UI. It does not carry pressure or tilt data into Windows apps, so pressure-sensitive drawing is better suited to working natively on the PC itself.
Does it work over cellular, or do I need Wi-Fi?
Both. On cellular, Remio adapts to your connection and falls back to an encrypted relay route if a direct path is not available. Most 4G and 5G networks carry a smooth 60 fps stream, and sharpness drops before frame rate does.
