How to reset File Explorer Navigation Pane width to default in Windows 11

If you changed the Navigation pane width in File Explorer on Windows 11/10, and you want to now get it back to the default width, then you can reset the File Explorer Navigation pane width to default with the help of the Registry Editor.

The Navigation pane in File Explorer shows Quick Access, This PC (including hard drives), Library folders (such as Music, Videos, Pictures, etc.), and Network drives. By default, Windows shows a set width, which doesn’t get changed even if a folder or partition name is hidden because of it. However, if you altered the Navigation pane width earlier and you now want to restore the default width, there are two ways to do it.

First, you can click the edge of the navigation panel and drag it towards the left or right side. However, this trick works if you remember the width preciously. The second way is to use the Registry Editor to delete a value citing the current width of the navigation pane.

Reset Explorer navigation pane width to default

1. Press Win+R to open the Run prompt.
2. Type regedit and hit the Enter button.
3. Click the YES button in the UAC prompt.

5. Delete the PageSpaceControlSizer value.

Before going forward, you should backup Registry files and create a System Restore point first.

Now, press the Win+R hotkey, type regedit and hit the Enter button. It will show you the UAC prompt where you need to click the YES button.

Following that, your PC should open Registry Editor. Next, navigate to the following path-

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Modules\GlobalSettings\Sizer

Here you will see a DWORD (32-bit) Value called PageSpaceControlSizer. This is the current width set to the Navigation pane.

You need to delete this value. For that, right-click on it and select the Delete option.

Following that, click the Yes button to confirm the removal.

Now, you need to restart File Explorer. Also, close and open File Explorer if it is opened already. You should see the default width of the Navigation panel now.

For your information, the PageSpaceControlSizer value gets created automatically whenever you open the File Explorer and the data changes when users change the width manually.

That’s all!
