>> Does anybody know if it is possible to install the Tabled Editon
"extentions" to this usual Windows XP? <<

Short answer, yes and no ;-/

There are some options with XP Pro, and, surprisingly, the answers lie
in the windows help file by searching on "handwriting" and "ink" In
addition to showing how to "turn on" the handwriting features, there
were url's for downloading the components referenced which were not part
of the xppro os.

A couple of years ago, I set up the handwriting extensions on my xppro
desktop using an external pen tablet and was able to experiment and test
a number of tablet features, but it was far from ideal.

In addition, some of the tablet specific os features such as the tip,
windows journal, etc, were not available.

Information on exactly what your goal is would help give better answers.
