Windows Longhorn build 4053

Windows Longhorn build 4053 is a Milestone 7 build of Windows Longhorn, which is reported to have been shared online on 1 March 2004. Overall, this build is very similar to build 4051, but with networking bugs patched.

This build was compiled in evaluation mode and can be installed on the current date. Attempting to log onto the desktop once the timebomb has been triggered will return the user to the login screen.

Setup
Setup is mostly similar to previous builds of Longhorn. You can also upgrade to this build from previous builds too.

Theming
If Windows Explorer or Internet Explorer stops responding, the classic title bar may be seen.

Control Panel
The normal method of creating user accounts does not work in this build. However, accounts can still be created by going to run and typing in either  or , or you can port   from another build to replace the one in the   directory in order to get it to work. Alternatively, the Local Users and Groups MMC snap-in can be used.

Start menu
The most frequently used items list of the Start menu resets itself after every reboot.

Notifications
Notifications tend to reappear quite a lot. Fully closing the notifications may take several attempts.

Upgrade
On some machines, after the first reboot during an upgrade, an "Unknown problem in upgrade happened" error will appear, and clicking OK will cause the machine to restart. After restarting, setup will continue normally until another reboot takes place, in which "The file WinSetup.dll could not be loaded or is corrupt. Setup cannot continue." will appear. Clicking OK will restart the computer and on some machines, there will be no mouse and keyboard support (since the hardware detection phase of setup did not start), and the only workaround is to reinstall Windows. This bug persists until build 4093.
