Windows Longhorn build 4086 (main) 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 tenth set of his 33 Longhorn/Vista builds on 2 February 2020 with its other compiles.[1]
Fixes[edit | edit source]
- The Scheduled Tasks folder is now functional again (unlike builds from 4081 to 4085 Lab07_N).
Bugs and quirks[edit | edit source]
Installation[edit | edit source]
- As typical of builds in this build range, it tends to take a long time to install and can be unstable.
- Partition and format a drive from a previous or later build prior to starting installation.
No mouse driver in WinPE[edit | edit source]
On some computers and virtualizers, the WinPE doesn't support the mouse, so you must use the keyboard to navigate the WinPE. This seems to be related to using a PS/2 mouse, as USB mice seems to work fine for the setup.
Upgrade[edit | edit source]
Attempting to upgrade from other builds is not possible, causing either of these 2 things:
- A bugcheck with error code 0x7E after the second reboot. This is commonly observed when trying to upgrade from non-componentized builds, such as 4074 (via a registry tweak that reports it as a componentized build).
- An error while copying files.
WordPad[edit | edit source]
WordPad does not start, as it will display with Failed to create empty document instead.
Outlook Express[edit | edit source]
Outlook Express does not start due to registry errors and certain dependencies on WinFS.
Themes[edit | edit source]
- The Windows Classic theme will not function due to a broken
Windows Classic.themefile.
Explorer[edit | edit source]
- CD and DVD drives behave like local disks.
- Help and Support crashes Explorer.
- Explorer can randomly crash for no reason under normal use, such as adding Sidebar tiles, but this depends on the hardware being used.
Control Panel[edit | edit source]
- Hardware and Devices folder does not open.
- Phone and Modem Options Control Panel applet name is empty.
- Computer Management displays script errors due to missing registry entries.

Safe mode[edit | edit source]
