What i need is very rare. I searched for hours in the web for an answer, couldnt find any...... I am running on winxp and i want to have an extremely fast way (without having to boot the OS) to run batch files containing regisrty modifications. For example after i have finished multicasting an image of 113GB to 120 computers, i need to open each one of them going in some sort of command line feature (win98 start up or anything else that could work) and be able to change the ip, the cs serial, the generals serial, the locks that need to be putted(disabling right click etc.) and all sorts of modifications from client to client that u can imagine with a single batch file containing the registry modificationd needed to be that possible(i already know those). Now the fastest way i found was booting the **** system in "safe mode with command". Not good enough because it takes too much time. I was able to setup a netcafe of 120 pc's in just one night, when i was using win98. Now i HAVE to move in winXP becasuse some games just wont play in win98(DOOM3). And if u people cant tell me a way to do the reg-modifications faster than having to boot up and then run the batch file.......then i will have to work something like a week(with the store closed) to be able to upgrade my netcafe.
