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

Bugs and quirks[edit | edit source]

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

Control Panel[edit | edit source]

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 control userpasswords2, or you can port nusrmgr.cpl from another build to replace the one in the \WINDOWS\SYSTEM32 directory in order to get it to work. Alternatively, the Local Users and Groups MMC snap-in can be used (lusrmgr.msc).

Start Menu[edit | edit source]

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

Notifications[edit | edit source]

Notifications tend to re-appear quite a lot. Fully closing the notifications may take several attempts.

Upgrade[edit | edit source]

After the first reboot when upgrading from build 4033 or build 4029, an "Unknown problem in upgrade happened" error will appear, 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.
