What you’re seeing
- A notification saying "An app default was reset" after a restart or update.
- PDFs open in Microsoft Edge even though Adobe Acrobat or another reader was set as the default.
- Web links open in Edge instead of the chosen browser.
- Staff keep changing the setting, only for it to revert within days.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- Windows resets a file association when it believes the change was not made through its protected settings flow.
- Feature or cumulative updates restore Microsoft's defaults for PDFs and web links.
- A group policy or default associations file pushed by IT overrides individual choices.
- The PDF reader's own update or repair re-registers itself incorrectly, which Windows then rejects.
- A damaged user profile cannot hold its default app choices.
Why it matters
When PDFs keep opening in the wrong app, staff lose access to features they depend on, such as signing, form filling, redaction and stamping. Contracts get signed incorrectly, forms are saved without their fields, and time is wasted reopening files. It also generates repeated support requests that make an office feel like its computers are never quite under control.

Frequently asked questions
Why does Windows keep switching back to Edge?
Windows protects default app settings and resets them if it sees a change it didn't approve, and some updates restore Microsoft's defaults.
Can it be locked in for everyone?
Yes, businesses can set defaults centrally so they hold across updates, which avoids each person fixing it by hand.
Can AskTechGurus set this up?
A certified US engineer can sort it out with you in a remote secure session, from $99, and you pay only when the defaults stay put.
