Windows: Change first day of the week

On my machine, since I’m using the US regional settings, the week starts on Sunday:

Windows clock first day of week sunday
Windows clock first day of week sunday

It’s usual for the US and Australia but in Europe everybody considers the week to start on Monday, not Sunday. So you’d expect this:

Windows clock first day of week monday
Windows clock first day of week monday

In Windows 7 you can change it in the regional settings:

Regional settings first day of week sunday
Regional settings first day of week sunday

You can change there the first day of the week to Monday:

Regional settings first day of week monday
Regional settings first day of week monday

Now on Windows XP, you do not have this drop down list for the first day of the week. It’s automatically set based on the regional settings. But you can change it in the registry (HKEY_CURRENT_USER\Control Panel\International -> iFirstDayOfWeek):

Registry first day of week sunday
Registry first day of week sunday

There change 6 (Sunday) to 0 (Monday):

Registry first day of week monday
Registry first day of week monday

This also works on Windows 7 (but it’s easier to change it in the regional settings).
