Windows Terminal gets servicing updates as version 1.26 slides
Microsoft dropped two servicing updates for Windows Terminal today. Versions 1.24.11911.0 and Preview 1.25.1912.0 hit the channels simultaneously on July 16. The goal is simple. Fill the gap until version 1.26 lands. That major release is getting pushed back, so the team decided to patch the cracks instead.
If you're running the stable channel, you get version 1.24.11911.0. Preview users can grab 1.25.1912.0. The stable build has likely absorbed most of the big features from the March 5 launch already. That includes the rewritten Actions page, full-text search across settings, and the Kitty Keyboard Protocol support. You probably updated to those servicing releases back in May or June. This is just housekeeping on top of that.
Bug fixes and technical deep dive
The headline fix is a crash when dragging tabs between windows of different sizes. It hit some users consistently and skipped others. Microsoft calls it an EnablePainting viewport desync rooted in a prior renderer change. It's gone now.
There's also a workaround for a deadlock with NVIDIA graphics drivers. The terminal is speculatively moving initialization earlier to pre-warm a SHGetKnownFolder call. It's a bit of a hack, but it stops the freeze. Head here to see if your driver is affected.
Memory corruption in the DRCS font subsystem is also patched. DRCS lets apps define custom glyphs. The fix prevents writing glyphs that are too tall. That closes a potential vulnerability window.
Preview gets a few extra treats. The reloadEnvironmentVariables setting finally works with wt.exe <command> again. Action names in the editor also update more reliably. If you rely on the command line, keep in mind that the Preview channel often gets the command-line fixes first.
Not cheap to track all these down. The NVIDIA fix alone required digging into driver behavior. The tab drag crash was platform-dependent, which makes reproduction a nightmare.
What's next and how to update
Version 1.26 is delayed. Microsoft hasn't given an ETA yet. You're looking at a wait.
You can grab this update through the Microsoft Store. Search for "Windows Terminal" or "Windows Terminal Preview." WinGet users can run winget install Microsoft.WindowsTerminal or winget install Microsoft.WindowsTerminalPreview. GitHub releases are also up at the repository page.
Head here to the Windows Terminal GitHub release page 1.24.11911.0 and here for Preview 1.25.1912.0 for the full changelog.
