I'm not too sure what you need. You already have, (or will have), the 20 computers for the school and they will have Windows XP Professional pre-installed.
You have, (or will have), other teaching software to install on each?
If so, won't that software already be on CD? In which case it is just a (laborious) process of going to each computer and using the CD to install the software.
If you want to speed up the process, you can try and copy the CD's to blank CD's so you can do more than one PC at a time. Is that what you mean?
Or do you mean you want one of the PC's to act as a server and networked to all the others, so that they access the other teaching aids from just the one PC?
20 school computers will have win xp proff preinstalled.
need to add other teaching software to all others..
how can i create a disc to take from one machine to another to load in place of loading each bit of primary school software on each machine? one at a time?
