Hi gsbill00,

Did you follow Sony guidance when upgrading to 8.1?

This would hopefully ensure that all drivers and utilities were retained.

Thank you for the reply, however I have been running 8.1 for about a year now, this happened with the latest Microsoft Update. The result has been a total loss of screeen brightness control, either using the the [Fn] F5/F6 or Personalise settings.

Good News. Microsoft have just done another huge update, and guess what, my brightness controls have returned.

I can see again
