Windows Longhorn build 4017 is a Milestone 5 build of Windows Longhorn. On 23 January 2020, this build was listed on a thread by Grabberslasher, founder of the UX.Unleaked blog, to be released to the BetaArchive FTP, and was released as the first two builds of his 33 Longhorn/Vista builds on 24 January 2020, alongside build 4029 (Lab06 n).[1] This build shares a lot of similarities with build 4015 (main), including a working Desktop Composition Engine that isn't different to the aforementioned build.

Unlike other Longhorn builds, it was compiled in evaluation mode, and can be installed on the current date. Once the timebomb is triggered, Windows still functions, but a Windows Product Activation error message will show up that this build must be activated. Additionally, the timebomb is extended to 445 days, being one of the "Longhorn" builds that has the longest timebomb.

Changes[edit | edit source]

  • The Avalon taskbar/sidebar application has been removed.
  • The sidebar now doesn't have rendering issues upon changing the resolution.
  • The EULA reference during setup now says "Longhorn" instead of "Whistler".

Setup[edit | edit source]

Bugs[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.ini file. Although booting will still be possible, NTLDR will default to C:\WINDOWS.
  • The hardware detection portion of setup may crash, and an error message may appear as well. Simply press ALT+TAB to access the error message, and click OK. This will, however, skip the Out-of-Box-Experience.

Themes[edit | edit source]

Upon changing themes, the icons on the desktop will not show correctly. Refreshing the desktop will usually fix the problem.
