It’s slightly less devastating than data loss, but still…
Microsoft Surface Pro X owners are finding that their cameras suddenly stop working altogether. The problem started this week and many have been trying to determine the root cause. Definitely not the driver, reinstalling various versions didn’t restore functionality for anyone experiencing the problem.
Instead it appears to be a certificate that has expired, because rolling back the system date before May 22 brings the camera back, for a while. However, rolling back the date has negative effects, as there are many authentication methods that require an accurate date. It also only lasts until your clock strikes 23.
If you or someone you know has a Surface Pro X with this issue, you shouldn’t spend too much time troubleshooting as we now know it’s not something you can easily fix.
