No volume after downloading windows 10 on my lenovo lap top?

Get the audio device driver for "Misery 10" from Lenovo support for whatever model "lap top" you have.

We're M$. Resistance is futile. Your puters and lappies will adapt to service us. We will add your technology to our own.

Going back to your original OS is your best bet. Windows 10 is a nightmare of an OS that is going to get worse as time goes by. Between the forced updates to the built in back door you will have no idea what is happening to your puter. It's funny how you never had a problem with your original OS, then you upgrade, and now people tell you that if you go back you are going to have problems. DO THEY KNOW SOMETHING ABOUT THE ROLL BACK WE DON'T.

If it has been less then 30 days try this. Back up everything important and then try clicking Start, Settings, Update & security, Recovery, Go back to (last version)

If it has been more then thirty days then you're out of luck and are going to have to do it the hard way. You won't be able to use the recovery partition since you upgraded to 10. M$ deletes it to keep you from going back. It is my opinion that M$ deletes the recovery partition to keep people from going back to their old OS. I guess if you write as many bad OSes as they do you got to find a way to make it look like everyone likes it. If M$ deleted your recovery partition then you will need to order the recovery DVD's from the manufacturer. Some manufactures still have recovery DVD. Post your make and model and I'll see if they are available.

If you had Windows 8.1 you can use the link below to go back. You need to back up everything up and make sure you have a good product key on the bottom of the lappy. I do suggest that you download all your drivers before attempting this.

If you had Windows 7 then posts the make and model and I'll see if it can be done. We have had a lot of success so far getting people back to 7 if you are willing to do the work.

Make sure when you go back that you DO NOT let these updates in. M$ is now hard coding spyware ( back door ) into Windows 7 and 8. Look for these updates and see if you have them. KB 3068708 KB 3022345 KB 3075249 KB 3080149 These updates give 7 and 8 the same spying capability as 10 has.
