One criticism of my last Vista installation time blog was that I performed an upgrade over an existing Vista beta. Fair enough comment though I think a lot of people are going to upgrade existing XP boxes instead of performing a clean installation. In any case, I decided to perform a clean installation with Build 5728 (the previous build was 5600) on the same Pentium 4 2.8GHz PC with 512MB RAM (performance rating = 1). Here’s what I saw.


  1. 1140 Booted PC with DVD inserted
  2. 1143 See Install Now screen
  3. 1144 Formatted the hard drive
  4. 1145 See message Expanding Files
  5. 1155 100% files expanded
  6. 1156 Unattended reboot after briefly seeing the message Installing Update
  7. 1158 Completing Installation
  8. 1208 Created user account
  9. 1210 Account login screen appears
  10. 1211 Desktop appears. Elected to install updates which consisted of installing the sound device driver, Windows Defender, and Windows Defender definition updates
  11. 1212 Vista ready to use

So, it took a grand total of 32 minutes from start to having a useable desktop to install Vista RC-1 Build 5728. I’m not sure I attribute all of the time savings (compared to nearly two hours for Build 5600) on performing a clean install though. Once at the desktop, Vista seems much more responsive than previous builds (including 5600).

The desktop PC I’m testing on is low-end (Performance Rating = 1) according to Vista. So, I’m pretty impressed by the speed at which applications like Internet Explorer and Firefox are launching and running (web page refreshes, etc.). Media Center, which was more than a little pokey in earlier releases seems faster too.
