GFN WindowMover is a Windows tool to lock a target window to a defined area. It was built for the GeForce NOW game window, but it can also be used for other applications.
- Fixed mode: lock a window to a saved position and size.
- Wrapper mode: lock a window into a live wrapper area that you can resize and move.
- Process picker UI: choose the target process from visible windows.
- Enable/Disable toggle: quickly turn locking on or off.
- Multi-monitor support: works across the full virtual desktop.
- Start the application you want to control (for example GeForce NOW in-game window).
- Run
GFNWindowMover.exe. - Click Choose Process and select the target process from the list.
- Select the mode:
- Fixed Position/Size
- Wrapper Window
- If you use Fixed mode:
- click Open Fixed Region Editor
- move/resize the editor to the desired target region
- click Save Region or Save + Run Fixed
- If you use Wrapper mode:
- click Start Wrapper Mode
- move/resize the wrapper window; the target is locked to the inner area
- Use Disable to temporarily stop locking and move the target window freely; use Enable to lock again.
- Open the latest release.
- Download the Windows executable artifact.
- Run
GFNWindowMover.exe.
For contributor setup instructions, code style guidance, and test commands, see CONTRIBUTING.md.
- Target platform: Windows 10/11.
- Run the app with normal user rights first; if the target process runs elevated, start this app elevated as well.
- If process detection fails, use Refresh Process after the target window is visible.
- If window locking behaves unexpectedly, disable and re-enable locking in the main window.
