Hide Bing

In Microsoft Edge

• go to or create key HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge
• create a new DWORD (32-bit):
  • Value name: HubsSidebarEnabled
  • Value data: 0
• according to articles on the internet, you should reload policies (in Edge, go to edge://policy), I never had to - I just restarted Edge, and the Bing Discover button was gone

In Microsoft Search

• in the 'modern' Settings, choose Privacy & security
• then click on Search permissions
• in the Cloud content search section, disable both:
  • Microsoft account
  • Work or School account

• go to registry key HCU\Software\Microsoft\Windows\CurrentVersion\Search
• create DWORD BingSearchEnabled with value 0
  • this results in no Chat Bing AI results
  • but also no web results (but who cares)
• (this change doesn't require you to restart your pc)

• create registry key HCU\Software\Policies\Microsoft\Windows\Explorer
• create DWORD DisableSearchBoxSuggestions with value 1
• restart your pc (or Explorer)
  • this results in no Chat Bing AI results
  • but also no web results (but who cares)
