Hello, I am searching for this update(standalone) it extends DP expiration date to 2013 jan 15. If you have updated W8 DP x86 you can find this update in C:\Windows\SoftwareDistribution\ FAQ: 1. Why do you still use DP when CP/RP/RTM are out? I don't use but I want to use it on old Pentium M machine and Developer Preview works fine on them.. because it doesn't have NX/XD checks. 2.For what reason you need this update? Simple - to get other updates(bugfixes) till 15 jan.. 3. Developer Preview is Pre-Realease(Pre-Beta more precisely) and you want to use it as main OS? Nope.. dual boot with XP.
