Make File Explorer open to This PC instead of Home — via Winaero

The easy way

1. The easy way: File Explorer → … → Options → General → Open File Explorer to: This PC.

Registry change

Double-click a .reg file and confirm to merge it. Right-click → Edit first if you want to read it, which is always a good idea with any .reg file from the internet.

Apply

Windows Registry Editor Version 5.00

; Oddbyte.Me: Make File Explorer open to This PC instead of Home

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
"LaunchTo"=dword:00000001

Undo

Windows Registry Editor Version 5.00

; Oddbyte.Me: undo Make File Explorer open to This PC instead of Home

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
"LaunchTo"=dword:00000002

Same thing from a command prompt

Run in a normal (non-admin) Command Prompt or Terminal.

reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /v "LaunchTo" /t REG_DWORD /d 1 /f

Undo:

reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" /v "LaunchTo" /t REG_DWORD /d 2 /f

LaunchTo values: 1 = This PC, 2 = Home/Quick access. Winaero also lists 3 = Downloads (registry only), but a reader reported that value causing an error on 22H2, so it isn't offered here.
