Step 1 and 2 seem to be enough to enable focus follows mouse. Everything else just prevents windows from being brought to the front if you hover your mousr over them. Would you mind adding this as context to your guide @anshumanb?

Enable Xmouse (Focus Follows Mouse) in Windows

  1. Press Win + R, paste control.exe /name Microsoft.EaseOfAccessCenter into the Run dialog, and press Enter. In the window that opens, click on “Make the mouse easier to use”.

  2. Check the box for “Activate a window by hovering over it with the mouse” and click OK.

    This enables focus-follows-mouse with a default hover delay.

  3. To customize the behavior, press Win + R, type regedit, and press Enter to open the Registry Editor. Navigate to the following path:
    HKEY_CURRENT_USER\Control Panel\Desktop

  4. In the right-hand pane, find and double-click UserPreferencesMask. To prevent windows from automatically rising to the front when they gain focus, subtract 40 from the first two characters of the value. For example, if the value is DF, change it to 9F.

  5. Next, find the ActiveWndTrkTimeout value. If it doesn't exist, create it by right-clicking in the right-hand pane, selecting New → DWORD (32-bit) Value, and naming it ActiveWndTrkTimeout.

    • Double-click it, select the Decimal base, and set its value to the desired delay in milliseconds (e.g., 300 for 300ms or (hex: 12C)).

  6. Sign out of Windows and sign back in for the changes to take effect.
