[German edition<\/a>] Within last months I have read many speculations about Microsoft's intension to establish a kind of \"quick boot\" in upcoming Windows 8. The guys at German WinVistaSide.de took a view behind the curtains of Windows 8 Build 7978.<\/p>\n

<\/p>\n

MagicAndre1981 from WinVistaSide did an in deept analysis of Windows 8 boot process using xbootmgr trace<\/em><\/em>. He found something called HybridBoot in Windows 8. This mode will be invoked on each shutdown.<\/p>\n

In HybridBoot mode, Windows 8 terminates the user sessions (and also the the apps loaded within these sessions). Afterward windows 8 kernel and also all services will be set into \"sleep mode\". This means a memory dump is written into hybernation file (hiberfile.sys<\/em>). Then the power will be switched off.<\/p>\n

During next boot, windows boot loader don't need to load kernel modules, drivers and services from distinct files. Instead, the memory dump will be loaded from hiberfile.sys<\/em> and Windows 8 logon screen will be visible within a few seconds. MagicAndre1981 reported, here<\/a> (unfortunately in German), that a resume took only 7,5 seconds on his system. That's a funny work from thouse guys at WinVistaSide.de!<\/p>\n

Some other findings from Andr\u00e9<\/strong><\/p>\n

Beside this, I reported here in brief about a new extended virtual disk format (.vhdx). MagicAndre1981 told me in a comment, that these .vhdx files may be larger than 2 GB. Together with Hyper-V there will be a lot more options to virtualize guest operating systems as in the past. Andr\u00e9 reported also (see here), that PowerShell 3.0 will be incorporated in Windows 8 Build 7978. A WinVistaSide user speculates, that PowerShell 3.0 provides methods to access the new \"protogon file system\" (see here<\/a> and here<\/a>). I don't know, because I haven't had time yet to take a closer view.<\/p>\n

[Update:<\/strong> I just have seen, that zdnet editor Mary Jo Foley also posted an article<\/a> about Hyper-V in Windows 8. Maybe it's a bit more readable for native English language user. Mary Jo referenced also McLaws-Blog, who reported, that Hyper-V includes a number of new storage, memory and networking enhancements.]<\/p>\n
