Setup[edit | edit source]

Although setup is mostly similar to earlier builds of Vista, the setup autorun now mentions Beta 2 in place of Beta 1. The hard drive partitioning page now also has a new advanced option, which hides the latter drive partitioning tools unless clicked on.

New features and changes[edit | edit source]

Branding[edit | edit source]

This build has unique branding among publicly available builds, not even shared by its server counterpart, for Starter and Ultimate SKUs, where the Longhorn logo used since build 4044 is appended with a SKU name; in this case "Longhorn Ultimate" or "Longhorn Starter Edition", and the other SKUs have the same branding as build 5212.

Taskbar[edit | edit source]

The taskbar received a new tray icon for Network Connections in this build. Related to that, a new applet has been introduced, but it appears to be empty and cannot be closed, until explorer.exe is restarted.

Control Panel[edit | edit source]

Peer-to-Peer and Secure Startup applets have been added to Control Panel.

  • Secure Startup was later renamed to BitLocker, but references to the preliminary name survived in the form of internal component names.

Previous Version[edit | edit source]

This is the first build of Windows to include the Previous Versions section in a folder's or file's Properties window.

WinSAT Aurora[edit | edit source]

WinSAT is now functional, after being non-functional on builds ranging from 5048 - 5212, however it only contains Aurora, a feature used to test the computer graphics. It can be enabled by running winsat aurora. It is notable for using the purple aurora and Windows XP logo rather than the green aurora and the Windows Vista logo in build 5270.

32-bit EFI support[edit | edit source]

It is one of the few known post-reset builds to support booting from a 32-bit EFI implementation. This was soon dropped due to low demand from OEMs,[1] and would not reappear until Windows 8.

Bugs and quirks[edit | edit source]

Upgrade[edit | edit source]

Upgrading from Windows XP may prevent the user from logging in with the error Interactive logon process initialization has failed.

Zero-day timebomb[edit | edit source]

This build has a zero-day timebomb on the first boot. Once rebooted, the correct expiration date will be set.
