If you already own a computer running Windows 7 or Windows 8.1, then Windows 10 is going to be completely free — and updating should be really easy. Just make sure you don’t put it off too long if you don’t update within a year from Wednesday, you’ll have to pay for it.
If your Computer is up to date then the Windows Update icon should be appear in task bar.
Clicking on the icon will open up Microsoft’s Get Windows 10 app, which allows you to sign up to download the new OS and determine if your computer is compatible. Enter your email address into the system, and from there you’re pretty much set. Now you just have to wait.
Chances are good that you won’t actually be able to download and install Windows 10 immediately. Microsoft is rolling the OS out slowly to make sure that it has time to clean up any bugs that it discovers, so you may end up waiting weeks or more before you’re given the go ahead to install it. Once you are, Microsoft will download Windows 10 to your computer and then notify you with a pop up that it’s ready to install. Then it’s time to get going.
If you don’t see it by Wednesday, go to link given below,
And follow the instructions given in the link by Microsoft .
To get Windows 10 you need to take care of some other updates first. If you’re running Windows 7, make sure that you’ve updated all the way to Service Pack 1. To do that, go to the Start menu and search for Windows Update. If you’re running Windows 8, you’ll have to bump it up to 8.1. To do that, click the Store tile on the Start screen; inside the store, you should see an icon for the update.
Once you’re on the latest version of either operation system, the Get Windows 10 app should be available, and you’ll be able to grab the free update.
If you’re running Windows Vista or XP, then you’ll have to pay to update to Windows 10. It costs $119 for Windows 10 Home and $199 for Windows 10 Pro, but you’ll want to take more into consideration than just the price.
Windows 10 has the same system requirements as Windows 7 and 8, but those requirements are still substantially higher than those for earlier versions of the OS. Make sure that your computer meets these minimums before updating:
The Basic Requirements :
Processor : 1Ghz
RAM : 1 GB fo 32 Bit & 2 GB for 64 Bit
Graphics support : DirectX 9 or later with WDDM 1.0 Driver
Display : 800 x 600 Resolution
Even if you do meet those requirements, you may still want to think about getting Windows 10 another way: by buying a new PC. You can buy a new laptop for the same price as you can buy Windows 10 Pro, which is worth keeping in mind.
This first step isn’t mandatory, but it’s a good idea: back up your computer. If you can, make sure that all of your most important files are saved outside of your PC. More than likely you aren’t going to need this, but it’s better to have it in the event that something goes wrong.Once Windows 10 starts installing it will take almost up to 1 hr or may be less depending upon your Computer. It may take more time ,don’t be a panic and be a relax and let the installation complete.
After completion windows may ask to configure some settings, just do that and it will not take much time. After done all this thing your are almost done.
After Restarting windows please do check windows update to make sure that you have not missed any recent updates.
