>>Heh, I forget where it is every time I install XP on a new machine. On WinXP Home this option cannot be disabled at all. Finally I start to use some tweak program to setup multiple options for a new installation (tell me if you are interesting, I will find where to download it).

>Yes thank you, that would be interesting.

My favorite all-in-one tool: X-Setup Pro 6.5 at http://www.x-setup.net/.
There are approx. thousand of tweak plug-ins within it (don't forget to auto-update them after installation) but they are well categorized and the search tool is available.

>>And also I'm going to wrtie an ini file to set up all these options automatically on XP installation.

>Just knowing how to create the ini file would be useful. Thank you.

Everything is in the Support\Tools\Deploy.cab archive on WinXP CD. Extract and read Deploy.chm to begin.
Not only automated installation is provided, you can also predefine default settings for manual installation.
Very very nice thing - auto-run custom programs after installation. This could be used to install service packs, updates and even some software. And of course you can auto open .reg files with RegEdit to write some setting to registry, for example, to disable simple shares on installation.
