Microsoft targeted to get Windows 10 running on a billion devices by 2018, for which a major pie is prepared to enable the user to upgrade their older Windows editions to Windows 10.\r\n\r\nWhile going back to the more trusted desktop operating system, the majority of users completely given up Windows 8.1 and a large number of them are even still on Windows 7. These hundreds of millions of users are the target of Microsoft upgrade plan. So, when its extended support commitment ends, millions of PCs won\u2019t be running Windows 7 in January 2020.\r\n\r\nMicrosoft\u2019s unprecedented free upgrade offer will expire on the one-year anniversary of Windows 10 by July 29, 2016. Let\u2019s explore it more for you, what happens after that?\r\n\r\nFOR ONE IS RELUCTANT TO UPGRADE\r\n\u201cI don\u2019t want to upgrade, I hate Windows 10\u201d\r\nIf \u2018Get Windows 10\u2019 promptly made you believe something but no one is forcing you to do so. You should eventually understand that Microsoft will cease support for Windows and Window8.1 in spite of staying with your current Windows version. So, hopefully, you should try out Windows 10, it will work for you otherwise, you can always rollback to your existing Windows installation.\r\n\r\nFurthermore, one day you\u2019d eventually need to get on to Windows 10. Most new PCs in the market come preloaded with Windows 10 already, and OEM sales of new PCs with Windows 7 will officially end on coming October 31, 2016.\r\nONE WANT TO KNOW THE UPGRADE PROCEDURE\r\n\u201cHow can I upgrade to Windows 10?\u201d\r\nWell, as you may have been living under a rock all the time or you really love deadlines, but now you can have very short time to upgrade your existing Windows PC to Windows 10 for free.\r\n\r\nJust go for the Windows 10 upgrade page, download the upgrade tool to upgrade qualified Windows 7 or Windows 8.1 devices running a non-Enterprise edition. Devices not eligible for a free upgrade are running Windows RT, Vista, XP, or an older Windows OS. You can create a bootable USB drive, DVD, or ISO to install or reinstall Windows 10, and to create your own installation media with either a USB flash drive or a DVD, you need the nifty little media creation tool, so just give it a try.\r\n\r\nWell, as part of this upgrade offer, Microsoft offers you like-for-like Windows editions. If you are upgrading from Windows 7 Starter either Home Basic or Home Premium, you\u2019ll get Windows 10 Home as an upgrade and in case you are upgrading from Windows 7 Professional\/Ultimate, you\u2019ll get the Windows 10 Pro edition as an upgrade. Though Windows 8.1 Pro users get upgraded to Windows 10 Pro, but similar is the case with Windows 8.1 users gets upgraded to Windows 10 Home.\r\n\r\nIn addition to the upgrade, make sure that your copy of Windows is activated before the upgrade. If it\u2019s not, you can\u2019t activate Windows 10 after the upgrade.\r\n\r\nONE THAT CAN REINSTALL WINDOWS 10 IN FUTURE\r\n\u201cHow can I reinstall Windows 10 in future?\u201d\r\nThe existing Windows license is used in the process for the Windows 10 upgrade, to record a \u2018digital entitlement\u2019 on Microsoft\u2019s activation server that associates a Windows 10 \u2018digital license\u2019 with your specific hardware actually require no product key.\r\n\r\nHopefully, you have Windows 10 for free on that device after your upgrade. But, if you upgraded your Windows 7 or Windows 8.1 device before July 29, you deserve to reinstall Windows 10 on the same device for any reason any time. Your digital license won\u2019t expire and it\u2019s good for the lifetime of the device. As long as your device fulfills the hardware requirements for the upgrade, you can install any future releases of the operating system, including the upcoming Windows 10 Anniversary Update.\r\n\r\nAll is good except a significant change to your hardware, such as replacing a hard disk or the motherboard; you\u2019ll require using Windows 7 or Windows 8.1 product key for reinstalling Windows 10 until Microsoft\u2019s activation servers continue to accept those keys. But, if Windows 10 does not re-activate automatically, you must use the new Activation Troubleshooter to re-activate or contact Microsoft support for assistance.\r\n\r\nYou should bear this thing in mind that this isn\u2019t always the case and we\u2019ve recorded instances where an entire PC upgrade \u2014 motherboard, GPU, HDD, did not create any activation issues at all.\r\n\r\nONE IS UNWILLING TO UPGRADE NOW\r\n\u201cI don\u2019t want to upgrade right away\u201d\r\nThe free upgrade offer will not be extended despite all possibilities, another offer for a discounted in-place upgrade cannot be ruled out. At the same time, with all things unchanged until July 29 passed, you\u2019ll have to pay Rs 7,999 for Windows 10 Home and Rs 14,999 for Windows 10 Pro.\r\n\r\nYou may consider Windows 10 in future because of the reason that you\u2019re not ready right now, so what you need to do is to obtain a Windows 10 digital license at the moment, rollback to your existing Windows 7 or Windows 8.1 installation, and install Windows 10 whenever it seems appropriate.\r\n\r\nSimilarly, upgrade yourself to Windows 10, and whenever your license is recorded, you should rollback to the Windows edition you upgraded from with the Recovery options. The rollback process will restore the previous Windows version after it wiped out the Windows 10 upgrade. It takes about 10 minutes.Also, note that after a Windows 10 upgrade the rollback option is available for only 30 days.
