Windows 10 Now

As I mention earlier, Change is good for you. Accept it quickly.
SO NOW
Here is a change!
for those using windows
Windows users can now upgrade to windows 10 for free. but within some limited time. so do it quickly.

You have one year from the launch to accept the free upgrade to Windows 10, so you must do it before 29 July 2016. After you have accepted the free upgrade, there is no further charge for the life of the device. It remains to be seen whether Microsoft will offer any deals after the deadline, but Windows 10 costs £99.99 or $119.99 from Microsoft. Other suppliers may sell it for less.

Windows 10 is “Windows as a Service” and it is frequently updated from the cloud. You can download Windows 10 and keep it on a DVD or USB stick, which is handy if you need to upgrade several PCs. However, the download will soon be out of date, so that is not a long-term solution.

Windows 10 has a cloud-based authentication system, so you must install the upgrade before 29 July 2016. If you miss the deadline, Microsoft’s servers will not authenticate the free upgrade and you will be asked to pay.

Microsoft is not giving away copies of Windows 10, just offering to upgrade existing licences for Windows 7/8/8.1 to Windows 10 for free. If you want to run two versions of Windows, you have to buy two licences.

Getting authenticated

The correct procedure is to install Windows 10 as an in-place upgrade, after which Microsoft’s online servers will authenticate it automatically. Once Windows 10 has been authenticated, you can do a clean installation from a USB stick or DVD, and that will also be authenticated automatically. (There is a possible workaround.)

However, following user complaints, Microsoft changed things with Windows 10 version 1511, the Fall Update released last month. This can be activated using the Windows 7/8/8.1 key from your laptop: it’s probably on a COA (Certificate of Authenticity) sticker.

To check, go to Settings, select Update & Security, and then Activation. If it says, “Windows is activated” then you are OK. If not, change the product key to your old Windows 7 key. If the worst came to the worst, you would have to ask for a phone activation, or re-install Windows 7 from a backup and then install Windows 10 again.

go back to Windows 7

Yes, if you act within 30 days. Go to Settings, select Update & Security, and click Recovery. This allows you to go back to your previous operating system, which has been stored in a “Windows old” folder. Windows eventually deletes this to save space.

Note that the Windows 10 Fall Update is a new version of Windows 10. When it’s installed, the earlier version of Windows 10 becomes the new “Windows old”. After that, you can’t simply go back to Windows 7/8/8.1.
