Ok made an modified dvd of win 7 build 6956, and tablet pc pen didn't worked until i copied Magnification.dll into system32 folder. i think this file might need to be protected. I installed it without system restore and User Account Control. It seems to be a big mistake. Also v-lite put an product key into unattended xml which didn't let me to install until i manualy deleted <key> tag. i removed 3 GB(media Center/speach/etc..) from the instalation dvd but after instalation i got only 1 GB freed in plus of a normal install.
