Windows 8 build 8277 is a build of Windows 8, which was uploaded to BetaArchive on 4 January 2019 as an x64 checked/debug version. It is the last build to use the flag from Windows XP, Vista and 7 in both the setup and charms bar. Despite having a higher build number than the official Consumer Preview, it was compiled nine days earlier, in a similar fashion to Windows Vista build 5712, Windows 7 build 7106 (winmain) and Windows 10 build 10102 (winmain_prs). The wallpaper has been reverted to the Windows 7 login screen background. This build still uses the Windows Developer Preview boot screen branding instead of the "betta fish" as in the official Consumer Preview build.

Unlike build 8220, this build shows the Microsoft Confidential watermark in both the desktop and winver.

Bugs and quirks[edit | edit source]

Installation[edit | edit source]

Use an IDE hard drive to install this build, SATA and SCSI hard drives might encounter partitioning and formatting issues during setup.

Compatibility[edit | edit source]

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

Boot screen[edit | edit source]

On Legacy BIOS machines, the boot screen uses 16:9 aspect ratio, thus, i.e., on 4:3 monitors it gets stretched down horizontally. UEFI configurations are not affected.

User Account Control[edit | edit source]

When launching Windows settings such as Device Management, the User Account Control will go off, even if it is set to "Notify me only when apps try to make changes to my computer (default)", like in Windows 8 build 8056 (fbl grfx dev1), possibly other Windows 8 builds, and Windows Vista. Disabling UAC completely works fine, however.
