Windows 10 Professional OEM for 3 euros: It is known that from January 14, 2020, the Microsoft will stop arguing with security updates on functional Windows 7 system. This is of course expected by the company and its developers, as current Windows 7 users will have to upgrade to the operating system it has been promoting for so long: Windows 10.
If you are one of those who are thinking of upgrading, see the following offer:
What's the difference;
It's made of two διαφορετικές εκδόσεις. Η μια είναι μια retail έκδοση κατευθείαν από την Microsoft και με όλα τα χαρακτηριστικά της ενεργά, ενώ η OEM έκδοση διατίθεται από μεγάλους κατασκευαστές συσκευών. Η OEM έκδοση είναι limited.
It can be activated on a PC, and it does not have it free phone support. The OEM key cannot be used to upgrade from Windows 7 or 8.1. But it works great for some fresh clean install.
The retail version does not have these three restrictions. As for everything else, it is exactly the same product.
According to the above, if you want to upgrade from Windows 7 use the retail key, while if you are thinking about a clean installation the OEM key is cheaper and will work fine (but only on the computer where you will install and activate it for the first time).
The retail key can be activated on a different computer, as long as it is disconnected from the first one.
Reliability: we tried them wrenches of the company and they work without any problems.
