I'm having a strange issue with my Windows 11 desktop where it randomly starts typing complete Japanese sentences in romaji—like someone's actually typing them out—once every few days. I initially thought it might be due to wireless interference from a family member's keyboard, but they use a wired keyboard, and no one was typing at the time it happened. I've run a quick scan with Windows Defender, and it didn't pick up any threats. I'm curious about what could be causing this—is it interference, malware, or something else entirely? Any advice on how to troubleshoot this would be super helpful!

It sounds like you're dealing with some kind of keystroke injection rather than just interference. I’d suggest unpairing and then re-pairing your Logitech receivers. Also, double-check that you haven’t accidentally installed a Japanese input method or hotkey—it might be switching your input mode and sending out text.
I once faced something similar that felt like a remote hack. It can seem like Windows 11 has some quirky bugs related to USB receivers lately. I ended up downgrading to Windows 10 using logkeys.com, and it totally resolved my issues. If you have the option, a fresh installation could be worth considering to eliminate those ghost inputs!
You should definitely start by checking for remote access or malware. Open up the Task Manager and look at the active sessions and startup programs. Run an offline scan with Microsoft Defender or Malwarebytes for thoroughness. For hardware troubleshooting, unplug both Logitech receivers and test with a wired keyboard. Sometimes Logitech devices can create ghost inputs, especially when using their G Hub software.

Interesting! In your case, did you notice it also typing coherent sentences? Mine's definitely entering meaningful messages in Japanese.
