Hi User,

 

Thank you for choosing McAfee Support Community

The command mentioned is for upgrade to Windows 10 OS only, but as i can see from your description , you are trying to upgrade from Windows 7 to Windows 8.

I would suggest to disable PBA and perform the upgrade.

 

Also let me know if you are trying upgrade through SCCM or WSUS?

Hi,

 

The command is to be executed only when you are upgrading to Windows 10. As you are upgrading to Windows 10, you can directly upgrade.

Re: Unable to upgrade windows 7 to windows 8 pro

Hi Team,

 

I've tried to upgrade as normally on several Encrypted windows 7 systems, but it's got an error like, "We couldn't install Windows 8 'we've set your PC back to the way it was right before you started installing Windows8.'

 

But at the same time I'm able to upgrade the Windows 7 systems which are not having McAfee Drive Encryption. 

 

Hence request you to please assist me with proper solution for "McAfee Encrypted systems upgrade from Windows 7 to Windows 8"

 

Thanks..!!
