This is true of most OS'es...
You have found one solution... just adding each user to the admin group. Which IMO is a very scary one since you have just given every user the equivilant of root on all those machines.
Another solution is to do a littel reading on windows security and create a group that will allow the users access/rights to do the things you want them to do but not allow them to do other things. BTW check out the rights for Power Users... sounds like that is about the rights you want them to have.
As for having to add them to each machine....
If you have a real windows domain that the machines are in then just add the users to the domain level group and that will take care of it for all the machines in the domain when they log in.
Overall I would suggest thinking about what you would do if this were a pure linux environment, then researching what the windows ewquivelant is and doing it.
