I've searched the archives but could see a reply to this so here goes: I installed from a newly purchased set of CD's at the weekend (after quite a long time of carefully buying my hardware - one bit at a time ) I've installed a fair few editions of XP in my time (as a keen amatuer I might add, not IT person) so was a bit perplexed by some of the things I couldn't do. So could someone just comment on the following as I think I'm getting the right idea but just need some pointers. After installing the second disc, it asked me for winXP service pack 2 disc. Luckily I'd picked a copy up from the counter of my place of purchase (Novatech) but the installation wasn't having any of it so had to cancel that part of the installation. However, after a reboot from the completed MCE2005, I then tried the SP2 CD and it installed great heaps of files on the hard drive. I don't understand why a new version of MCE2005 should be asking for a service pack? Currently XP as an OEM for instance say's that SP2 is included. Also, I noticed I can install hardware and download the drivers from a CD but it wont allow me to install the software from the CD. It will frequently give an error message RPC unavailable. This made me stop and think. Am I looking at this the wrong way, maybe I shouldn't be thinking normal PC at all. Also the normal help feature is disabled or not installed although I noticed windows update is now a seperate menu. In the end, I thought I'd leave it all alone with connection to my network still to be done and the media center setup still to be started. I enjoy learning so thought I'd spend this week trying to glean what I could from various sources before I start again this easter weekend. So any hints and pointers would be gratefully received.
