Windows XP undocumented programs

There is a lot of goodies buried in the Windows XP. It is a shame that the documentation is so poor. I have collected here info about the programs I found in \windows\system32 directory. I started them with a parameter '/?'like 'chkdsk /?' and copied here the description. Some programs don't tell anything. Some explain that 'This program can not be run in 32 bit environment', or something as usefull.

The reason why some programs give help and some don't, lies in that almost no part of the system is originally Microsoft. Most part originates from some other programmers and clued to the packet we know as Microsoft Windows. This also explains some of the real peculiarities and problems in Win.

Some information about Windows XP internals can be found from Microsoft pages

Bold font here indicates that the program is exceptionally usefull.

This list might give a partial explanation why windows installation takes so much space.

I'll be wery thankfull, if you can send me more information so I can publish it here. Even small pieces might help some other reader. Please emeil it to:
