Can I upgrade from Windows 7 Professional 64 bit to Windows 8.1

Can I upgrade from Windows 7 Professional 64 bit to Windows 8.1. I want to preserve the applications already installed, users accounts, my documents, etc.

I was wondering if I simply put Windows 8.1 on A USB stick and have it be the first boot option, then I will get to the point where it says upgrade or new installation. I hoping I can upgrade from there.  Can I?

You can upgrade, when you boot the USB windows 8.1 installation, the first option is upgrade from windows 7 installation.

Yes you can as noted above. Please note that upgrades like this frequently do not work and always bring old problems along with them.

This is an opportunity to clean things up with a fresh install and I do recommend that to you.

Yes, you can.  Have a valid Windows 8.1. You may have to reinstall some drivers, however. (Most of those from Windows update.)

Before you do a fresh install back up your personal data.  Software will have to be reinstalled.

Did you already do it?

I am interested because MS says only from win8 you can upgrade to 8.1 without losing your installed applications, so it would only be possible in a two-step-process: win7->8->8.1

keepObviously no one involved here has ever done it.

When I installed the Windows 8.1, I noticed the option to upgrade from windows 7, I didn't follow that path though.

Let me lab it and I will post my findings soon.

Can anyone help conclusively with this please? I see exactly what McKnife sees (Dec 29 posting) when trying a Windows 7 (Ultimate 64 bit) >> Windows 8.1 (Pro) upgrade.  I don't want to lose or reinstall all of my applications.  Has anyone done this?  Is there a way to do the upgrade and not loose all the installed applications?

And please don't advise me to do the clean install - I get it but I don't want to do it.
McKnifeCommented:
By now, I have done this a dozen times. Works only in a 2-step-upgrade:
7->8->8.1
jscarpenterCEOCommented:
So is that Win 7 to Win 8 to Win 8.1?
McKnifeCommented:
Yes. Only then you can keep all settings and applications.
