Windows 10: Wifi, bluetooth and other software failing after W10 updating

Since last June, wireless devices are turned off, several days the speakers also, and DVD works bad.

I've attempted many solutions but there is no success: DISM (no fails detected), updating Win drivers, updating Dell drivers -all of them are ok- but problem persists. Ethernet however works well. Remote diagnostics have also been made from manufacturer's website.

When attempting to turn on bluetooth a blue restart screen pops out with different error messages: "Kernel security check failure" (2 times); "IRLQ nor less or equal" (3 times).

My device is a Dell Inspiron M731R

Thank you in advanced for your attention and help.

Windows 10 fails to update


When you finish testing the Avast suggestion, make sure that you restart your machine.

Then if the issue persists, please return to the trouble shooting list in post# 89

I think there are three steps that remain; the WU troubleshooter, reset WU components, and manual WU reset.
