Trying to get a windows 10 home laptop to windows 10 pro

Helping out a church with a laptop they bought by mistake with window 10 home on it.  they need windows 10 pro because  of the server essentials domain they have.

The OS on this latop got corrupted as part of a windows update.  I pitched that if this was windows 10 pro / on the domain, it would have been backed up.  So they want to get this to windows 10 pro and they are looking to go through tech soup for that.

I have a win 10 install media thumb drive - when I've used it before (on machines with win 7 originally) it would ask what version of win 10 to install -- home, pro, eterprise, etc.  and then ask for a license key. you could skip the license key and if  the machine had been upgraded to win 10 (under free upgrade in that first year, etc.) it would auto activate.  or I would think OS would run but only short term till you enter a key.

On this win 10 home machine, when I boot off the win 10 install media, it must be reading the bios (that's where win 10 keys are stored now?) and seeing it's a home machine... so it installed that without asking what version to install.

We are getting a get genuine license from tech soup for win 10 pro for this machinee.  but ( a seperate issue), mirosoft / tech soup only lets them place 1 order EVER for get genuine licenses... so I am asking them how many licenses to get.  While they debate that / till we place the order for the licenses, I want to start getting this machine going

There's a spot in windows 10 home for update where you can enter a win 10 pro key and the machine will become a windows 10 pro machine.  Would you think I can build this machine as win 10 home, install office, etc THEN when we get the win 10 pro get genuine licnese (for win 10 pro), we can enter that and this machinee will accept it?

I've heard in previous OS, you have to use brand specific install media for the key / sticker to work.  or similar difficulties. Think the get genuine key has to be entered on a machine built with certain media / went directly to win 10 pro?  The get genuine page does say it's for machines with illegal software or legit older versions of winddow / home verisons.

Or is there a place to get the get genuine install files now and without a key it'd be in that limited functionality mode till we get the keY

Or a way to get the standard win 10 install media to show the choices for what OS to install?

 Or best way to get moving on this till we get the win 10 pro get genuine key?

The machine was running Windows 10 Home and so there, you can reinstall Windows 10 Home and it will pick up the license from the Microsoft Licensing Server. That part should be easy (and free).

Now they should be able to purchase a Pro key and add the key. Pro upgrades are not enormously expensive.

OK, but say I want to go from home to pro and want to do a clean install of pro with the install media and pro key.  Can't seem to do that with the install media that offers you to choose the os when you run it on a windows 7 / non win 10 machine.  seems just because it shipped with 1 os, you want to install a different OS if you have a license key for it.

With what you have , do a clean install with Home and upgrade. Otherwise you need to purchase a Pro license to install which would be more expensive

The Pro license is more expensive than the upgrade

There is really very little difference between Home and Pro... What media you install with isn't important. If you have to version upgrade dialog available, and put in a valid pro key, your system will become a pro system. You do not need to reinstall from other media... If the machine ever gets hosed again, you will most likely have to use the upgrade process again. Keep the key available for that machine...

Techsoup's "Get Genuine" Microsoft products are for non-profits to get compliant with licensing - that's why there's the "one off, never again" restriction.  

If you want to move from a valid Home install to Pro you should really look at their Upgrade package.  These use volume licencing so ideally you should move all their Windows installs to this.  If this is the only machine you have it might make more sense to buy additional upgrade licences as an "investment" on future hardware - particularly if they are going to buy OEM.  You might be tied to a minimum of 5 but for validated non-profits you're looking at less than $20 each.

Although the Techsoup offering is volume licensing for Enterprise you get the option to downgrade to Pro as part of the package and the online download gives you both options as installation media.

For small numbers get MAK's from Techsoup otherwise you have the additional hassle of maintaining a KMS server to keep them validated.

Meant to add re your 'not much difference between them'.  Yeah, higher cost for pro because it's got domain / business settings.  

Whether the pro bits are alraedy sitting dormant on the home install or it would download what I need isn't a big deal.

It was more that do I have to wait for the pro license key to either get my install media to offer pro as an option or go with building the home machine then be able to upgrade with the get genuine pro key.
