Teething problems are an unfortunate but expected occurrence when it comes to PC updates. Windows 10 had its fair share on launch – notably issues with the Start Menu.

While the Anniversary Update banished some of those early problems, others have come to the surface since the second biggest Windows 10 update landed at the beginning of August.

The main problem to hit a number of machines concerns webcams.  Certain types of webcam have been rendered obsolete following the Anniversary Update, because of changes to the number of applications that can access a webcam at once. Previous versions would only let one application access a webcam at a time, but the Anniversary Update allows multiple.

This has meant that even users of Microsoft’s own Skype application can’t make video calls without the machine freezing.

Not all users have been hit by the blackout though – only webcams that encode in MJPEG and H264 formats have encountered the problem.

One of the Windows Camera Team members apologised to users for not communicating the change on the Microsoft forum: “We dropped the ball on that front, so I’d like to offer my apologies to you all,” they wrote.

Microsoft is working on a proper fix which it hopes to roll out by September, but if you need to use your webcam now we have a couple of solutions that may work for you.

1. Roll back to the previous version of Windows 10

The Anniversary Update is the culprit, so how about getting rid of it for now?

You can roll back from version 1607 of Windows 10 (aka the Anniversary Update) to the previous version of Windows 10, but you can only do it within the first 10 days of upgrading.

If you’re not sure, give it a go anyway to check. It might be wise to back up any documents stored on your PC, just in case.

Open the Start Menu and click on the Settings cog.

2. Tweak the registry

This technique is a bit more complicated, so ensure you’re confident with what you’re doing. The workaround comes from Thurrott.com’s Rafael Rivera and we haven’t been able to test it ourselves, so proceed at your own risk.

Search Run in Cortana and type ‘regedit’.
