thank you for nice answers i got few more questions lol (sorry if i put it on same topic, but rather that than spam new threads) 1. as \$OEM$\$$\ represents \Windows\ folder, if i want to after OS install have custom folder in Windows folder (like \Windows\My new folder\) do i then just create empty folder via rclick in $OEM$\$$\ or i must do it via batch with MKDIR ? 2. this is regarding hotfixes, since after XP SP3, XP got huge number of hotfixes, some are for same thing but later trough months i guess updated (like the SMB hotfixes, there are like 3 or 4 of them) so should i only integrate latest one, or all of them (older and newer) and will only newest be applied or the every newer hotfix is made only as patch to last one and not as total patch to all prevoius bug ? (hope you understand) :S 3. regarding registry tweaks, if i execute registry tweak during setup, but tweak that is only for HKCU, will it work at all ? if i understand HKCU is only for current account logged in ?
