Microphone stopped working after running CCleaner

Following the latest Windows 10 upgrade, I ran CCleaner today to clean out the Registry - and the mic has stopped working (it worked fine post-update and before running CC). Can I reinstall the files that were deleted by CC?

Thanks.

Did you make a backup as CCleaner suggested when you cleaned the registry?

No, to be honest I didn't. But in the last few minutes the mic has started working again of its own accord! Thanks for your reply, though.

Good to hear it's started working again ?

It's not really a good thing to clean Win 10 registry anymore as Microsoft changes so many things in the updates.

And even if you did, some kind back up is a must.

Cheers!
