How to Uninstall Roblox Studio on Windows
Perform a deep-clean removal of the development engine to fix errors or clear up space. In this 2026 updated tutorial, I show you how to completely uninstall Roblox Studio from your Windows 11 PC. Whether you are troubleshooting the January 13, 2026 security update (KB5074109) issues or simply resetting your environment, I will walk you through the revamped App Management system and the mandatory January 2026 Identity Handshake.
With the January 12, 2026 Secure-by-Default update, Windows 11 has introduced Application Sovereignty Protection. I will show you how to navigate the biometric Identity Check to authorize the removal of High-Impact developer tools, ensuring that core engine files are only deleted by the verified device owner.
Step-by-Step Guide
Close the Studio Engine: Press Ctrl + Shift + Esc to open the 2026 Task Manager. Find any instances of RobloxStudio.exe and select End Task. I show you how to ensure the "Studio Update Agent" is also closed to prevent file locks.
The "Installed Apps" Removal: Press Win + I to open Settings, then go to Apps / Installed Apps. In the Liquid Glass search bar, type "Roblox Studio." Click the three dots (...) and select Uninstall.
The 2026 "Identity Check" Authorization: A walkthrough of the mandatory biometric prompt. I show you how to use Windows Hello (Face or Fingerprint) to authorize "Application Lifecycle Termination." This is a required security step in the January update to confirm you are the authorized user removing developer-level software.
Wiping the Local Meta-Data: Press Win + R, type %localappdata%, and find the Roblox folder. I show you how to enter this folder and specifically delete the Versions and Logs folders related to Studio. This removes residual 2026 registry pointers that often cause "Update Loops."
The Registry "Layout Reset" (Optional): If you are uninstalling to fix a broken UI, I show you how to go to HKEY_CURRENT_USER\SOFTWARE\Roblox\RobloxStudio in the Registry Editor and delete the LayoutSettings key. I explain how this wipes your custom docking settings that might be corrupted by the KB5074109 patch.
Handling the KB5074109 "Uninstall Loop": We look at a known 2026 bug where the progress bar hangs at 99%. I show you how to verify your build to ensure the January 17 Emergency Patch is installed, which resolves the "Credential-Hang" error in the uninstaller.
Uninstallation Integrity Verification: How to check for the green shield icon in your notification tray. This confirms that the removal has been verified by the latest 2026 Windows 11 security scan and your system registry is now clean of Studio services.
