On real hardware no problem with clean install, on VMWare upgrade by WU no problem too still testing, only clean install in VMware halts after initial boot. Will test x86 18346.1 too
18346.1 is excellent knock on wood so far clean installed feels like way windows should be , i think it is almost finished build 18378.1 should be IT!
The HAL of the 64bit version of build 18346.1 is not compatibel with vmware workstation/player up to the latest version: WinBSOD: Synthetic MSR[0x40000100] 0x5c WinBSOD: Synthetic MSR[0x40000101] 0x110 WinBSOD: Synthetic MSR[0x40000102] 0xfffff7fa8001f908 WinBSOD: Synthetic MSR[0x40000103] 0x19 WinBSOD: Synthetic MSR[0x40000104] 0xffffffffc0000001 This is BSOD 0x5c (HAL_INITIALIZATION_FAILED) with status 0xc0000001 (STATUS_UNSUCCESSFUL).
