Open Chrome Settings and review On startup and the Home button address; these control different pages.
What this symptom usually means
- one extension or profile is misbehaving
- cached site data is stale
- memory pressure is forcing tabs to reload
- DNS/network problems affect only some sites
- security software or a proxy is intercepting connections
Fix it in this order
- Open Chrome Settings and review On startup and the Home button address; these control different pages.
- Set the intended page, close Chrome normally, reopen it, and confirm which setting changed.
- Open chrome://extensions and review extensions added or updated near the time the homepage changed.
- Check chrome://management and chrome://policy if the settings are locked or keep reverting.
- Remove only extensions you recognize as unwanted, then run Chrome Safety Check and update the browser.
Isolate the failing layer
If On startup is correct but the Home button opens another page, change the Home button setting instead. A locked or reverting value usually points to browser policy or an extension, not a Windows homepage setting.
Retest the original failure
Set the intended startup page, restart Chrome, and open a new window. If it changes again, check extensions and management policy before deleting profile data.
When to use support or repair
If the same page fails in another browser, contact the site or network owner; if only Chrome fails, report its version and reproduction steps.
Record Chrome version, device/OS, profile and extension state, and the affected page without private tokens or account data.
Frequently asked questions
Should I reset the whole device immediately?
Usually not. Compare a private window and another browser first. Reset Chrome only after checking the profile, extensions and sync.
How do I know when the fix is real?
Set the intended startup page, restart Chrome, and open a new window. If it changes again, check extensions and management policy before deleting profile data.
