Hi. Been reading the excellent manual "The definitive how to guide" all about slipstreaming and creating an unattended CD (win 2000, in my case). It says for getting all the critical update hotfixes, to set up a 'base install' - with no updates, and use the Windows Update feature etc. Do I create a virtual machine partition and install a clean install of win2k here and use this method to collect all the critical updates numbers to get the files together? Thanks Railman5
