I am always amazed at how many simple questions I get asked – so be sure to keep asking! And as always, if you have a suggestion for post, let me know! Changing the Windows Desktop background is essentially the same in all versions of Windows with a slight change in Windows Vista and Windows 7.
Windows 7 – Changing the Desktop Background
First right click an empty spot on the desktop and from the right click drop down select Personalize – it is the last item on the menu.
From the Window that appears, you can select a background image or slideshow – which is new to Windows 7.
Windows XP – Changing the Desktop Background
Similar to Windows 7, first right click an empty spot on the desktop and select Properties form the menu.
In the Dialog box that opens go to the Desktop tab. From this tab, you can select/change the desktop background. If you do not see an image you want, you can click Browse and browse for an image.
