how to disable bottom/left menu tabloïds articles, without login?

Thanks — good screenshot. Two quick questions before exact steps: are you on Windows 10 or Windows 11, and do you want to keep the little weather/temperature on the taskbar while removing the article/news tiles, or do you want the whole panel gone?
Below are safe options for both OSes (all work without signing in to a Microsoft account).
If you’re on Windows 10 (News & interests)

• Quick (no registry): right‑click the taskbar → News and interests → Reduce taskbar updates to keep just the weather/temperature and stop rotating article updates, or choose Turn off to remove the feature entirely.
• Registry (make the change persist / scriptable):
  1. Open Registry Editor (regedit).
  2. Go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Feeds.
  3. Create or edit a DWORD (32‑bit) value named ShellFeedsTaskbarViewMode and set:
     • 0 = show icon + temp
     • 1 = icon only
     • 2 = disabled (turns the feature off).
  4. Sign out / restart Explorer or reboot. (Back up the key before editing.

If you’re on Windows 11 (Widgets)

• Turn off just the news feed (keep widgets like weather):
  1. Open Widgets (Win + W or click weather on the taskbar).
  2. Click the gear (Settings) in the top right → Show or hide feeds → turn the Microsoft Start / Feed (My Feed) toggle to Off and confirm. This removes the article/news feed but leaves other widgets (weather) available.
• Remove Widgets completely (if you don’t want the panel at all): right‑click the taskbar → Taskbar settings → toggle Widgets Off — or set TaskbarDa = 0 under HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced to hide it via registry.

If you want to remove the feed component entirely (no feed even in the background)

• You can uninstall the package that powers the feed (Windows Web Experience Pack). Open an elevated PowerShell/Command Prompt and run:
  winget uninstall "windows web experience pack"
  That removes the Microsoft Start/MSN feed from Widgets (you can reinstall later if needed).

Notes / cautions

• Turning off the feed or uninstalling the web experience pack will stop the article tiles but may change what other widgets display; uninstalling the pack is more aggressive.
• Registry edits and vivetool tweaks are reversible but always back up the registry or create a system restore point first.
• If you only want temperature visible but Microsoft’s UI won’t cooperate, you can replace it with a small third‑party tray/weather app (WeatherBar, Meteo, WeatherMate, etc..

Tell me:

• Which Windows version (10 or 11)?
• Do you want to keep the weather/temperature visible on the taskbar or remove the whole thing?

I’ll give the exact step‑by‑step you need (including the exact registry values / commands) for your system.
