I'm looking to develop a process that will help to maintain the performance levels of the Windows XP machines in our enterprise. I support about 250 Windows XP computers, so ideally I'd like to automate this process. Often times users complain that their PCs are "slow." Often times I will just image a new computer and switch out their old one. However, this is less than ideal as this process can take quite a bit of time. Any insight would be greatly appreciated!
