How to set the first of the week to be Sunday in the Calendar that is displayed in the System Tray of Windows Vista Home Basic. I tried setting the first day of the week to Sunday in Windows Calendar (thinking that it might work) and yet still it displays the first day of the week to be Monday. Moreover there are not settings available on the System Tray Calendar
Using regedit, browse to HKCU\Control Panel\International, look for the iFirstDayOfWeek key and set the value to 0 for Monday, 1 for Tuesday, 2 for Wednesday, etc ...

HKEY_CURRENT_USER\Control Panel\International. Also to open registory editor, press
start button + rsimultaneously and type
regedit.– NishantJan 15, 2015 at 13:51

First day of week. Click the link
Change date and time Formats
On the dialog that now appears, you can choose what one you want on the
First day of weekcombobox.
I ran into this exact issue when getting issued a UK-regioned desktop.
You need to go to
Control Panel -> Regional and Language Settings and pick a region that starts the week on Sunday, like US.
3To add to this: In Windows 7 this is an independent setting and can be found on the "Date" tab when customizing the locale.– JoeyOct 27, 2009 at 7:40

Just go Regional and Language Settings, there is a combo box: "First day of week:", and you know what to do next...
