In the annals of computing history, few devices inspire as much frustration and fascination as the Microsoft Surface RT. Released in 2012 and updated with Windows RT 8.1, these devices were beautiful pieces of hardware—magnesium chassis, crisp displays, excellent kickstands—sabotaged by a software prison.

Unlike its Intel cousins (the Surface Pro line), the Surface RT runs on an ARM architecture (NVIDIA Tegra 3/Tegra 4). Microsoft locked it down tight: you could only install apps from the official Windows Store. No legacy desktop apps. No command-line power tools. It was an iPad rival that forgot to let users be users.

But hackers, as they always do, found a way. Enter the Windows RT Jailbreak.

This article is your definitive guide to breaking the chains of Windows RT 8.1 on a Surface (original RT) or Surface 2. By the end, you will be running unsigned desktop applications, emulators, and classic open-source software on a tablet Microsoft declared dead years ago. jailbreak windows rt 8.1 surface

Final Verdict

Should you jailbreak your Surface RT 8.1 in 2026? Only as a toy or a learning tool. The process is stable but useless for daily web browsing or productivity. If you have an old Surface RT collecting dust, jailbreaking it is a fun Sunday afternoon project—just don't expect a miracle.

I. Why Bother?

Microsoft left them to die. The Windows RT 8.1 device—your beautiful, VaporMg-cased Surface—is a digital ghost ship. The store is closed. Updates are myths. But under that locked bootloader lives a full, ARM-native Windows NT kernel. It hungers for unsigned code.

Jailbreaking RT 8.1 isn’t about piracy. It’s about resurrection.

At the command prompt (usually X:\):

  2. Type runme.cmd (or msiexec /i jailbreak.msi).
  3. You will see a flurry of text – the script is patching ci.dll in memory. Wait for the line: "Jailbreak successful. Resuming boot..."
  4. The tablet will reboot one more time.
