Windows 8 build 8250 is the official Consumer Preview and Beta build of Windows 8, which was officially released to the public on 29 February 2012.^[1]^[2] Binaries from the ARM32 compile of this build were discovered on the Microsoft Symbol Server on 25 May 2022.

New features and changes

Branding

This is the earliest known build to drop the 2001 flag logo and replace it with the new tilted window logo,[b] and most user interface elements like the Charms bar, Windows Setup and iconography such as the disk drive icon used to indicate the currently-running Windows installation in the Computer system folder were all updated to reflect the newly-introduced branding. Certain resources (such as the Windows Anytime Upgrade application) still make use of the older logo design.

A new set of wallpapers and Start screen patterns exclusive to this build which feature an aquatic theme (itself an internal developer joke on the operating system having just reached the Beta milestone, previously done in the preceding operating system with build 7000) was added; although the latter patterns were already introduced by the time build 8220 was compiled. The default desktop wallpaper was changed to a dark teal-colored wallpaper containing a Metro-style betta fish along with a large number 8 on the left-hand side, and the default lock screen background was changed to a stock photograph of a coral reef taken by photographer Reinhard Dirscherl, licensed from Getty Images and altered to omit the background fish. Similarly, the boot screen logo bitmap was changed to depict a betta fish to reflect the current state of development.

Boot Graphics Library (BGFX)

System crashes no longer display a sad emoticon by default if a Japanese language pack is present and is being actively used. This change is also present in server builds irrespective of whether a Japanese language pack is active.

Other changes

The Win+X context menu (which contains a list of quick shortcuts intended for power users) has been added.

Bugs and quirks

Compatibility

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

Transparency effects in the Windows Basic theme

When using the Windows Basic (Aero Lite) visual style, transparency effects can be enabled by means of a bug in the Personalization Control Panel. To do so:

1. Right-click the desktop and open up Personalization. Now click on the "Window Color" link given at the bottom of the window. Keep the window open.
2. Open a separate personalization window and apply the Windows Basic theme.
3. Go back to the other personalization window from the start, uncheck the "Enable transparency" option and then re-check it. Click on "Save changes". This will cause glass effects to be enabled.
