About dialog | |
Windows Longhorn build 4050 (idx02) is a Milestone 7 build of Windows Longhorn. On 23 January 2020, this build was listed on a thread by UX.Unleaked blog founder Grabberslasher to be released to the BetaArchive FTP, and was later released in the fifth set of his 33 Longhorn/Vista builds on 28 January 2020 as a checked/debug build alongside build 4085 (Lab07_N).[1] It is the second publicly available Home Edition pre-reset build of Longhorn.
Setup[edit | edit source]
Although setup is mostly the same as the previous build of Windows Longhorn, a new Slate-styled background is used.
Changes[edit | edit source]
Login screen[edit | edit source]
- The login screen has changed once again, now it is transparent as it does not have a background. This is because, in these builds, the "SYSTEM" user account does not have a default wallpaper. This change was most likely done to in order to let OEMs put a logon background with their logos.[2]
- The Windows logo upon logging in now comes up instead of coming down.
ClearType[edit | edit source]
- ClearType is enabled by default again, after being disabled in Lab06_n compile of build 4042. This change would persist up to build 4074.
Bugs and quirks[edit | edit source]
winver
dialog[edit | edit source]
This build uses the older winver
banner first seen in build 4005 instead of the new one from build 4044, likely because the change did not make into Home Edition at that time.
Installation[edit | edit source]
- This build can not be installed normally due to an assertion failure in
AGP440.SYS
, thus resulting in a0x0000007E
(SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
) bugcheck when booting into the second stage of setup. To bypass this issue, set up kernel-mode debugging with WinDbg to ignore the failure[3] or replace drivers with ones from the non-checked/debug compile of build 4051. This error does not happen on real hardware that don't have an AGP slot. - When booting into the second stage of setup, the system will play a long beep.
- Due to this build being a PDC build like build 4051, this build cannot be normally upgraded from a previous build and can only be clean installed.
