You might have heard of Windows 10 coming out. What you may not have heard is that if you have a "qualifying" version of windows installed, you are eligible for a FREE upgrade to Windows 10. This will also depend on whether your system can handle it.
If you have Windows 7 through to windows 8.1, you may have noticed a windows flag that has come up in you notifications area. If you hover your mouse on it it will say "Get Windows 10"
Here is my blog post with a screenshot showing where:

Click on that windows icon and REGISTER your system. When windows 10 gets released, you will be notified.
If you do not have that icon in your task bar and you have a qualifying Windows version then you need to do the following:
1) Perform ALL your updates using windows update.
2) If the windows icon does not appear by the next day following your update perform the steps on this website:

NOTE: It is better to register windows 10 even if you are not sure if you want to upgrade. The simple reason is that once you register, you have up to one year to install it after its release. Hence there is no obligation to install it after you register.
You can to do this by the 29th of July (not long now from time of post!)
If after doing all this you do not see the "Get Windows 10" icon in your notifications area then it is likely that your system has been detected to be incompatible with Windows 10. After the 29th of July 2015, the icon should appear according to Microsoft, to provide you the option to register for Windows 10, but this will not infer that your system has become compatible.
Good luck with your upgrades!
