How will I know when Windows 10 is available?
Between now and launch, the following KB update (https://support.microsoft.com/en-us/kb/3035583) should be installed on your Windows 7/8.1 computer.

When I upgrade a preinstalled (OEM) version of Windows 7 or Windows 8/8.1 license to Windows 10, does that license remain OEM or become a retail license?
If you upgrade from a OEM version of Windows 7 or Windows 8/8.1 to the free Windows 10 upgrade this summer, the license is consumed into it. Because the free upgrade is derived from an OEM base qualifying license, Windows 10 will carry this type of licensing
too.
If you upgrade from a retail version, it carries the rights of a retail version.
Full version (Retail):
- Includes transfer rights to another computer.
- Doesn't require a previous qualifying version of Windows.
- Expensive
Upgrade version (Retail):
- Includes transfer rights to another computer.
- require a previous qualifying version of Windows.
- Expensive, but cheaper than full version
OEM :
OEM versions of Windows are identical to Full License Retail versions except for the following:
- OEM versions do not offer any free Microsoft direct support from Microsoft support personnel
- OEM licenses are tied to the very first computer you install and activate it on
- OEM versions allow all hardware upgrades except for an upgrade to a different model motherboard
- OEM versions cannot be used to directly upgrade from an older Windows operating system
What happens if I change my motherboard?
This will invalidate the Windows 10 upgrade license because it will no longer have a previous based qualifying license which is required for the free upgrade. You will then have to purchase a full retail Windows 10 license.
The edition of Windows 10 installed will be based on the logical edition of Windows installed,
ie. Windows 8 Core (Single Language) will be upgraded to Windows 10 Home, Windows 7 Professional will be upgraded to Windows 10 Pro.
