[luckylady1960]

My 23 inch touchscreen HP Pavilion 23-150z came with win 8.1..however, when win 10 downloaded it completely took 8.1 off......................how do I go back to 8.1..I own the media recovery disk set of 8.1

While Microsoft tells you that there is no risk in the Win10 Upgrade, because they let you believe that you can always revert back to your original OS and setup within 30 days, the ugly fact of the matter is that the Win10 GoBack function has proven to be unreliable -- and when it fails, it can leave machines in a corrupted state -- which doesn't always happen, but it does happen often enough to be a problem and you won't get any warning in advance that it is going to trash your PC!

If that is not bad enough, the Win10 Upgrade is know to corrupt the Recovery partition stored there by the OEM that built the original machine. This pretty much guarantees that no HP Recovery is going to work: http://h30434.www3.hp.com/t5/Desktop-Video-Display-and-Touch/HP-Recovery-Manager-Blocked-After-Windo...

This means that RESET no longer works on your laptop due to your doing the Win10 Upgrade.

To actually restore your PC to its original condition, you need something known as HP Recovery Media.

Ordinarily, I would recommend using HP Recovery Media to restore your PC to its original condition. That would erase the entire drive, format the drive, and install the OS, the drivers, and the HP utilities.

Unfortunately, there is no HP Recovery Media linked to the HP Product Page for your PC. This could be an oversight by HP, or it could also mean that HP no longer stocks the recovery media for your PC.

You can try contacting HP Customer Support directly, using the links below, to see if you can order if from them:

If you live in the US or Canada, contact information is on this page: http://www8.hp.com/us/en/contact-hp/phone-assist.html#section1

If you live elsewhere, contact information is on this page: http://www8.hp.com/us/en/contact-hp/ww-contact-us.html

NOTE: After you get through, stay on the line until you are finally able to talk to some one -- it can take a while!

If you have trouble finding a phone number, then try: 1 (800) 474-6836

However, HP Customer Support is generally not available on the weekends, so you might have to wait until Monday to contact them.

Sorry, missed that detail in your original post ...

Yes, insert the first disk, turn on the PC and follow the directions.

Good Luck
