Setup[edit | edit source]

Setup is practically similar to aforementioned builds of Vista, however the "Next" button is now much larger. The EULA has also been updated, and the wallpaper of the OOBE is essentially the same aurora wallpaper used in the first 2 stages of setup. Finally, the orb used during the OOBE has been changed with the start button orb, and it is positioned higher. You can even click on the orb, which has the same functionality as the Start button on the bottom-right.

New features and changes[edit | edit source]

Branding[edit | edit source]

If the Starter SKU is currently used, the "Windows Starter 2007" watermark will be used instead of "Windows Vista Beta 2".

User interface[edit | edit source]

  • The login screen now uses the aurora wallpaper.
  • The Start menu has received a few minor uplifts.
  • If the Windows Basic theme is enabled, the icon for the user's profile picture is now inside the start menu rather than popping out.
  • The tray on the taskbar has a new network icon, which can show connectivity and all WiFi ranges.
  • The Date and Time tray uses a new clock picture.
  • The Windows Basic theme has been updated with a darker title bar and redesigned caption buttons.

Applications[edit | edit source]

Internet Explorer[edit | edit source]

Internet Explorer 7 has received a few updates. This includes a new toolbar below the tabs section, tabs being slightly smaller, and the icon now changed to resemble that of RTM (asides from the icon in its about section which has a glowing effect on the top-right of its logo).

  • "Network Connections" has been improved and renamed to "Networks List".
  • Wireless Network Setup Wizard has been removed.
  • The "Windows®" screensaver was renamed to "logon".

Bugs and quirks[edit | edit source]

Upgrade[edit | edit source]

The wallpaper gets changed to img24 when upgrading from Windows 2000 or Windows XP. This quirk persists until build 5466.

Screensaver Properties[edit | edit source]

  • The "logon" screensaver shows up duplicated in Screensaver Properties.
  • "scrnsave" screensaver throws up a blank error.

Shutdown[edit | edit source]

The shutdown sound is cut off during playback.

Starter SKU[edit | edit source]

This is the first build to block processors newer than the Pentium III, as the following error appears if logging in with an incompatible processor:

You cannot use  with this computer because the [processor] component is not supported. Contact your computer manufacturer for assistance or try fixing the problem by running Windows® Update in safe mode.

To restart your computer in safe mode, click OK

According to documentation in the later build 5356, the Intel Celeron, Pentium III (except for Pentium III Xeon) and AMD Athlon processors are supported, but the Intel Pentium 4, Pentium M, Core and AMD Opteron (as well as any later) processors are incompatible.

To use the Starter SKU, it either needs to be installed on a computer or VM utilizing one of the supported processors or the CPUID needs to be modified to run it on newer processors. This works with VMware by modifying the VMX file of the VM, with QEMU by setting -cpu=pentium3 or 86Box by using the "Intel Celeron (Mendocino)" or "VIA Cyrix III" processor.

Without this, only Safe mode can be used properly.
