Windows Server 2012 Build 8250.0.winmain win8beta.120217-1520：修订间差异

'''Windows Server 2012 build 8250''' is the official Beta build of Windows Server 2012, which was released on 29 February 2012<ref>https://web.archive.org/web/20120302143325/http://blogs.technet.com/b/windowsserver/archive/2012/02/24/windows-server-8-beta-available-now.aspx</ref> along with the client counterpart. It was also additionally released in the form of a set of Repair Content Packages, which are used by <code>DISM /Cleanup-Image /RestoreHealth</code> to repair an existing Windows installation, making it one of the few remaining server builds to be released with a 32-bit counterpart after support for the x86 architecture was dropped with the release of Windows Server 2008 R2.

* Minor design updates have been introduced across the Start screen's user interface.

* The default layout has been changed to include the Windows PowerShell, Task Manager, Server Manager and Control Panel shortcuts.

It is the earliest known build to drop the 2001 flag logo and replace it with the new tilted window logo. The boot screen logo bitmap was changed to utilize a Metro-style betta fish along with the number 8 on the left-hand side. Certain resources (such as branding in the System Control Panel applet) still make use of the older logo design. The disk drive icon used to indicate the currently-running Windows installation in the Computer system folder has been additionally changed to use the new Windows flag.

The Boot Graphics Library has been updated to accommodate for legacy BIOS machines utilizing a widescreen monitor configuration; the boot screen, system crash screen and the second stage of setup therefore utilize 16:9 aspect ratio variants of the logo bitmap and Segoe Boot font face, with resources designated under the N moniker.

* The copyright date of <code>winver.exe</code> has been updated from 2011 to 2012.

* The setup background color has been changed from grayish blue to dark teal.

To install or run this build in VMware Workstation, the hardware compatibility version must be set to version 8.x or 9.x; otherwise, a bugcheck will occur.
