Goth aesthetic gone wild: a user's self-inflicted black screen of non-death in Windows 3.1’s

Software1 min read

A user accidentally made Windows 3.1 show only a black screen by setting every color to black. Microsoft engineer Raymond Chen shared the story while explaining what Windows does when you hold the power button.

A Goth theme gone too far

A customer called Microsoft support because Windows 3.1 seemed to show nothing but a blank screen after the logo disappeared. A support engineer found the cause. The customer had set every color option to black, including the wallpaper, title bar, buttons, window background, and text. Microsoft's Raymond Chen told the story while answering a question about the power button.

Key facts

  • Windows 3.1 was released a long time ago, in the early 1990s era of Microsoft's software.
  • The customer changed five main color settings to black: wallpaper, title bar, buttons, window background, and window text.
  • After eight seconds of holding the power button, Windows tries to save a kernel dump, which is a diagnostic record of the system's core state.
  • Microsoft labels these events 'long power button hold' (LPBH) failures.

What happens when you hold the power button

Holding the power button forces a PC to turn off. Chen explained that after eight seconds, the Windows kernel (the core part of the operating system) notices this forced shutdown. It then tries to save a diagnostic file. One detail in that file shows whether every pixel on the screen was black. This can point to a video driver problem, which is the software that controls the screen.

Why it matters

The story is a funny reminder that small settings can make a computer hard to use. Once the screen is all black, it is hard to see what to fix. It also shows how engineers use clues in crash data to find the cause of a problem, even a strange one.

What to watch

  • Chen suggested deleting the [colors] section from the win.ini file as one way to fix a black-screen theme.
  • Microsoft uses the LPBH data to find real power-button and screen problems in modern Windows.
  • Dark mode in today's Windows is still a topic that Microsoft works on.

Chocolate Caterpillar or Chocolate Teapot? Top up the disk space for Windows 10 to find out

A Marks & Spencer food hall sign on London's Oxford Street appears to show a Windows 10 error reporting low disk space, spotted by Register reader Aaron Colwill. He suspected Windows 10 21H2 LTSC was the cause, noting that LTSC 2021 support runs until January 12, 2027. The article jokingly contrasts the sign's storage demands, which require at least 32 GB, with a simple poster, and quips that a chocolate-based advert on a fragile operating system is fitting.

Developer Snacks: dotnetup Instead of rustup, Node 27, Rust Web Framework

Microsoft has released dotnetup, a toolchain manager for the .NET ecosystem, as a public preview, modeled on rustup and nvm and designed to keep .NET environments consistent across platforms. Also in brief: PDFsharp moved from MIT to a dual AGPL/commercial license in a minor release, angering the community, and a Node 27 alpha built on V8 15.6.75.13 raised its heap limit to half of physical memory (between 256 MB and 4 GB).

"Red Alert" turns 30: Why the C&C sequel is still cult

Westwood Studios' 1995 "Command & Conquer" was a landmark real-time strategy game, and its sequel "Red Alert" is celebrating its 30th anniversary this year. The follow-up keeps the core formula of the original while changing nearly everything around it, moving the story to 1946 with an alternate history in which Einstein removes Hitler from the timeline. Players can control either the Allies or the Soviets, whose units play noticeably differently.

Adobe Rival? How Good Is the AI Clone PhotoCraft? | c't uplink

In early October 2026, ArtCraft released vibe-coded clones of Photoshop, Lightroom and other Adobe creative programs, followed shortly after by imitations of Microsoft Word, PowerPoint and other software; it currently offers 13 free programs. In the c't uplink podcast, c't editor André Kramer, who tested the Photoshop and Lightroom clones, describes impressive but also disappointing aspects, noting that the menus, palettes and tool icons are all there but it is unclear whether they are backed by working functions. He calls ArtCraft an interesting concept study but says it must be judged differently as a productive tool.
