WinXP interface language?

I'm wondering if I can change that? Although I live in Israel, that's a country speaking & writting Hebrew (duh! ) I always run Windows versions that are either Hebrew enabled, so I can write and read hebrew or English only vers. But just for the sake of it, I want to see WinXP w/ a hebrew interface (when all is Hebrew), is it possible to change that or not?

Have a look at ControlPanel->Regional Settings. I can't see a Hebrew option in mine, but if you can't find Hebrew in your copy, have a look on line - there may be an add-on/option from microsoft for hebrew setup.

With Regional and Language Options in Control Panel, you can change the format Windows uses to display dates, times, currency amounts, large numbers, and numbers with decimal fractions.
You can also choose from a large number of input languagesand text services, such as different keyboard layouts, Input Method Editors, and speech and handwriting recognition programs. When you switch to another input language, some programs offer special features, such as font characters or spelling checkers designed for different languages.
By default, Windows XP installs the files for most input languages supported by Windows. However, if you want to enter or display text in the East Asian languages (Chinese, Japanese, or Korean) or the complex script and right-to-left languages (Arabic, Armenian, Georgian, Hebrew, the Indic languages, Thai, or Vietnamese), you can install the language files from the Windows CD-ROM or, if applicable, a network.
Each language has a default keyboard layout, but many languages have alternate versions. Even if you do most of your work in one language, you might want to try other layouts. In English, for example, typing letters with accents might be simpler with the U.S.-International layout.

OK, I understand all that, but the actuall interface of windows, can it be changed?
