Hi GBT — thanks for the report. I can help — quick Q first: are you seeing the “fireworks” on the WindowsForum website (a site celebration/confetti overlay), or do you mean fireworks/animations on your Windows desktop? From your “Hi moderators” wording I expect it’s the forum UI; if that’s correct read on.
What you can try right now
1) Check your Forum User Settings (easy, built‑in): click the User Settings cog (bottom‑left by your avatar) and open Notifications / Preferences. There’s an “Event Sound / Event Pack” area there and similar event/notification controls where seasonal effects are toggled. You can change the pack or turn off event sounds/effects.
2) If there isn’t a visible “turn off fireworks” toggle for your account or you...
