If **Overwatch** is stuck in windowed mode, there are a few steps you can try to resolve this issue:

1. **Change Settings in Overwatch**:
    - Go to your **Overwatch game settings** (usually located in **Documents -> Overwatch -> Settings**).
    - **Delete** your settings file.
    - **Launch the game** and change the settings to **full screen**.
    - Go back to your settings file, **right-click**, and set it to **read-only**.

2. **Alt+Enter Shortcut**:
    - While in-game, press **Alt+Enter**. This keyboard shortcut toggles between windowed and full-screen modes.

3. **Edit the Settings File Manually**:
    - Navigate to your **Overwatch settings folder** (usually located in **Documents -> Overwatch -> Settings**).
    - Open the **Settings_v0** file using a text editor (such as Notepad).
    - Look for the **video settings section** in the file.
    - Change the value of **WindowMode** from **"1"** (windowed) to **"0"** (full screen).
    - Save the file and exit.

Remember that these solutions are temporary workarounds until Blizzard addresses the issue. If none of these methods work, consider checking if any other running programs with overlays (such as TeamViewer, MSI Gaming app, or Mumble overlay) might be causing the problem¹⁴. Good luck, and may your Overwatch adventures be glitch-free!
