Thank you I will see what happens when I download Windows 10.  By the way, do I have to do anything other than download, I mean what about the data already on my computer, do I have to get the download done by a professional or can computers users who have no real tech knowledge do it?

Excuse me for my ignorance but what's Kodi and would Netflix play with through this?

I am going to reinstall windows 7 first so have a clean OS to start . Then install windows10 by doing this hope to have a few years before needing to reinstall as you could lose windows 10 on a reinstall after the free 12 months is up as you need a copy of windows 10 to reinstall .  

Windows OS's up until now slows down a bit over time this is why you need to reinstall at around say two or three years to bring the windows back to full speed , like when you first got your new Pc if want too  . May be in windows 10 they have fix this on going problem with windows time will tells. 

There is no need to install Windows 7 at all. You can clean install Windows 10 from a DVD-ISO or USB. Again there is no expiration of 12 months (read my previous reply).

There is no need to worry about speed. Windows 10 will install no differently than Windows 8.1 or older. You will be able to get a standalone DVD-ISO.

Also for those wondering where the product key will be stored. It'll be stored in Windows Store. So if you need to do a clean install of Windows 10 you'll only have to sign into Windows Store to activate your Windows 10.

When she says "Norton product" that includes Norton Internet Security and Norton 360.

The Windows 10 compatibility assistant only runs once a month, and only in the background (You don't see it running.).  

However, if you want to force Windows to check for compatibility issues, open Command Prompt by (in Windows 7) going to the start menu, typing "cmd" (no quotes), right clicking the program that comes up, and clicking "Run as Administrator".

Type a password (if required) and click "Yes" if User Account Control comes up.

Next, type the following exactly as it appears, including the slashes, backslashes, and quotation marks:

schtasks.exe /Run /TN "\Microsoft\Windows\Application Experience\Microsoft Compatibility Appraiser"

That should do it.  In 15 minutes or so, your compatibility check should be ready and waiting within the Get Windows 10 app.  I believe that, for Windows 8.1, it should be the same, except that you would use the Charms bar (the bar that comes up on the right when your mouse is in the upper-right corner) and click Search, then type "cmd" (again, no quotes) and follow the above instructions from there.  However, I don't own a Windows 8.1 PC, so it would be helpful if someone could confirm this.

Alternately, you can open Task Scheduler (same method as opening cmd).  Within Task Scheduler, navigate to "Task Scheduler (Local)/ Task Scheduler Library/ Microsoft/ Windows/ Application Experience".  Next, right-click on "Microsoft Compatibility Appraiser" and click "Run".  That should be finished within the same amount of time.  Personally, I like the Command Prompt method because I like to do stuff manually on computers, especially modifying it (without breaking it).  Right now, I have a personal photo on my login screen background, but that's for another thread.

Please ask if you need any more help.

Phoneman is quite right. This is total nonsense - if you upgrade within a year of July 29th 2015, then it will be free forever. If you leave it for more than a year you will probably have to pay although I strongly suspect this will be a token sum and will be quite inexpensive.

There is no subscription service whatsoever - this is true whether you get it free within the first year or pay for it thereafter or get it pre-installed on a new PC. There are no subscription fees for Windows 10 whatsoever.

MS want everyone to upgrade - it costs them money to have to keep supporting numerous old versions of windows and with the PC market having shrunk in recent years they have made a commercial decision to essentially give it away to upgraders in the consumer market in the hope that their support obligations will be reduced in the future. They will still make money by charging OEM's (the people who make new PC's with Win 10 such a Dell, HP etc..) for the copy of Windows 10 that  they put on your new PC although even those fees are reduced and/or waived on small screen devices.

So while it might well be true that  this is a commercial decision that they hope will pay for itself in the longer term rather than pure altruism - the fact is that it is free for end users who upgrade.
