OEMs won't be able to sell PCs with Win7 / 8.1 starting November
Windows 7, perhaps Microsoft's most succesful release of Windows, along with the less popular Windows 8.1 won't come installed on large OEM PCs after October 31, 2016.
The move comes as Windows 7 rapidly excels towards its end of extended supported, which will occur at the beginning of 2020, having already lost mainstream support at the start of 2015. Just like each operating system has a date that it stops receiving updates, there is also an end-of-sale date, the date until when large OEMs can continue pre-installing a version of Windows. In the case of Windows 7, it was already meant to have stopped being pre-installed, but Microsoft allowed the Professional edition an additional two years until October 31, 2016. Now time has almost run out for both Windows 7 and 8.1 as their end-of-sale dates approach.
Beginning Nov. 1, Microsoft's largest partners, the so-called royalty OEMs like Dell and HP and Lenovo, will no longer be able to build and sell new PCs running any version of Windows except Windows 10.
That's actually a two-year extension on what would have been the normal sales lifecycle for PCs running those earlier Windows versions. But the clock is finally running out.
The end of the Windows 7/8.1 sales lifecycle doesn't mean that those older versions of Windows will be completely dead, of course. As I've explained in the past, the support and sales lifecycles are completely different. (See "What the Windows 7 Pro sales lifecycle changes mean to consumers and business buyers.")
Windows 7 will continue to receive security fixes via Windows Update until Jan. 14, 2020. Windows 8.1 will be supported until Jan. 10, 2023.
In addition, the fact that large OEMs will no longer be able to install older Windows versions on new PCs for sale through retail and commercial channels doesn't mean you're out of options. Here's a partial list of exceptions that will allow businesses and consumers to continue running their old, preferred Windows version:
- Existing inventory PCs that were built with older Windows versions before the deadline can still be sold. For months, at least, you'll be able to find those PCs on retail store shelves and in distributors' warehouses.
- Downgrade rights Any new PC you buy that has Windows 10 Pro preinstalled by the manufacturer comes with downgrade rights to Windows 8.1 Pro or Windows 7 Professional, for as long as Microsoft provides support for those earlier versions. You must supply your own installation media, and you have to activate manually.
- Custom images Corporate customers with volume licenses for Windows that include imaging rights can use custom images incorporating their preferred Windows version. For large customers, OEMs can assist in the installation of those images.
- System Builder OEMs White-box PC makers who purchase OEM System Builder media for installation on new PCs can continue to build and sell those PCs. Microsoft won't be stocking the channel with new OEM media, but past experience suggests there will be plenty of inventory for years to come.
- Retail upgrades If all else fails, do it yourself. Microsoft no longer manufactures retail copies of older Windows versions, but here too there's plenty of inventory in the channel and nothing to stop you from doing your own upgrade.
Of course, there are perils and pitfalls associated with running the increasingly aging Windows 7, especially on newer hardware. System manufacturers have no economic incentive to develop drivers and support tools for older Windows versions. Most downgrades will work, but some components might not work properly, or at all.
On new systems with Intel's Kaby Lake processors, versions of Windows before Windows 10 will not be supported at all. That doesn't prohibit you from trying to install Windows 7 on one of these new devices, but don't expect any support from the PC maker or from Microsoft when you inevitably run into problems.

on small team time is needed too

but after extensive use of W10, i wouldn't consider a buy with W7 (and even more W8.* of course).
W10 work better and use less ressources and even some program that doesn't work since W7 work again...

As someone who primarily uses Linux on a daily basis (including at work), I don't really understand what people hate so much about Windows 10 compared to 7. There are only 2 things I found especially annoying:
1. It advertises way too many MS products and in a pretty intrusive way.
2. It seems to be even more bloated than Windows 7, which was already too heavy for my liking.

Windows 10 is the best OS Microsoft has to offer, as well as being the most recent. Hence no reason for the vast majority of people not to use it on a new system... Windows 7, while very good, is 7 years old now and it's only going to have more and more issues with compatibility over the next few years and beyond.

These are good reasons and the fact that there's nothing wrong with Win7 and as a result, there's nothing appealing with Windows 10. Using less resources? good for tablets and devices with less than 2GB of RAM but doesn't matter at all with a good computer, it's not like Windows 7 was bugged and a memory hog. For references, I use Windows 10 everyday at work and Windows 7 at home.

I hope that the ReactOS system gets more funds and will be developed faster..
