Windows 10: Upgrade to Win10 using previous upgrade key

I upgraded from Win 7 to Win 10 2 years ago when MSoft was giving out free upgrade keys. Used Win 10 for 6 months and then my PC was bricked by a May 2017 update which necessitated recovering back to Windows 7. I still have that key on the PC. Can I use it to upgrade the same PC again? Thanks

Win10 Anniversary upgrade

Hello - I'm trying to upgrade to the Win10 Anniversary on a client's laptop. The laptop previously had Symantec Endpoint Protection, but it was removed before the free upgrade was performed from win7 home edition. The copy of SEP was not compatible with
the upgrade to Win10, but it was supposedly successfully removed.

Now the Anniversary upgrade stops and reports that it can't continue due to incompatibility with SEP. I've checked the startup, there's no SEP listed, there's no active SEP components listed under the task manager, and I'm unable to manually remove registry
keys through the regedit program.

So: would it be possible to:

Roll back to the previous win edition, reinstall SEP, then remove SEP, and upgrade to Win10 again?

Manually edit the registry (assuming that I can find the offending key(s)) so the installation can complete?

I don't have access to the latest copy of clean wipe, so I'm not sure that would help.

Please provide any suggestions and thanks in advance

Upgrade licence key to WIN10 online

Hi,

I installed WIN10 Pro Preview a couple of month ago to my step father computer. The Preview is getting to expiration and I try to make him upgrade to WIN10 (hard thing cause I'm not living in the same country as him).

The thing is, when he try to install WIN10 with the installer tool and try to enter the licence under his computer which is initially for WIN7 it doesn't work.

So I guess the best thing would be to install WIN7 back and upgrade but sounds not like the simpliest thing.

Is there a way to upgrade the licence key online ? Or can we call the support for software to ask them to upgrade the key ?

 

Win10 Upgrade

Hi,
KeithHover. If you're still getting this error code, try the troubleshooting steps found below and let us know how it goes:

• Disable (preferrably uninstall) your Antivirus utility before attempting the upgrade.

• Disable General USB Devices (example - Smart Card Reader).

• Do a clean boot and try again.

• If you are upgrading using the .ISO file, disconnect from the Internet during setup, if you are connected by LAN (Ethernet) or Wi-Fi, disable both and attempt setup again.

• If you are updating through Windows Update, when the download reaches 100% disconnect from the Internet LAN (Ethernet) or Wi-Fi and proceed with the installation.

• If that does not work, try using the .ISO file to upgrade if possible.

• If you are connected to a domain, switch to a local account.

• If you have any external devices attached to the machine, disconnect them (example, USB keys, external hard disk, printers, non-essential devices).
