Setup[edit | edit source]
New features and changes[edit | edit source]
- The wallpaper has changed to a Milestone 5 background, being slightly darker than the Milestone 4 background and containing the Windows logo instead of the Longhorn logo.
- The latter year in the Longhorn branding in "winver" and About Program dialogs has been changed back to 2003.
- A new login screen is utilized, replacing the Windows XP login screen. It also uses the wallpaper found in builds 3706 to 4001 albeit being zoomed in on the top-right, however it doesn't use animations found in later builds.
- Windows Explorer has been written in .NET managed code, although this often causes memory leaks and frequent crashes.
- Parental Controls is updated to now restrict games that are rated higher than a specfic ESRB rating.
- This build includes Libraries. The libraries included is the Photo and Video Library, Music Library, Document Library, and Game Library; the latter doesn't work. It was later introduced in Windows 7.
- WinFS now works, but it often causes memory leaks.
- Notifications once again have been slightly updated.
- The Desktop Compositing Engine can be enabled with the
uxdesk.dll,DceStartcommand in the Run dialog box. Note that a DX8 graphics card is required or DCE will crash. Only window transparency is included.
- The Plex theme has received a few updates, such as buttons now having animations upon hovering over them.
- The Windows start button has changed, being different than the start button shown from builds 3683 - 4011.
- The glass borders make their first appearance in this build, but can be difficult to run without DLL patching. This variant of DCE is also included in builds 4017 and 4020.
- There is an early version of a new Help Center included in the
C:\Windows\HSXfolder. Opening it causes a Trust Advisor warning to pop up.
Sidebar and taskbar[edit | edit source]
The new taskbar given from the Windows Sidebar is enabled by default, and you can no longer get the old taskbar with the sidebar enabled. This new taskbar overrides any theme that is utilized. Tiles for the sidebar have also been updated slightly, such as the search tile, which has been modified to be slightly more fitting.
Bugs and quirks[edit | edit source]
Installation[edit | edit source]
- Many drivers aren't installed by default during the hardware portion of setup and have to be installed manually.
- On some installs, once copying files has completed, setup will fail to create a
boot.inifile. Although booting will still be possible,
NTLDRwill default to
- The hardware setup tends to hang easily, after a while, you can press ⇧ Shift+F10 to open the Command Prompt. Then, run
taskmgrand terminate the process
setup.exeto log in. Due to this, you will also not manage to reach the Out-of-Box Experience.
- Most copies of this build's installation media are not bootable due to corruption, since it results in an "NTLDR is missing" error. If booting from the installation media results in an "NTLDR is missing" error, it can either be upgraded from an earlier build (except build 4011 on some machines, which will give a
0x0000006BBSOD) or it can be fixed with a patch. The ISO file of this build found on BetaArchive's FTP server does not have this issue.
- On some machines, booting from the CD may take longer than expected.
Login screen[edit | edit source]
Password hints have no effect on this build as the new login screen has no option to show a hint.
Memory leak[edit | edit source]
As with most later Longhorn builds, this build's Explorer tends to leak memory after a while. Turning off the Sidebar reduces the effect of the memory leak.
WinFS and related services are also affected by major memory leaks. Disabling WinFS solves the problem.
Drivers[edit | edit source]
- When certain Anti-virus drivers are installed, inserting or unplugging a USB device may result in a
