Microsoft have announced that Windows 10 will be available on July 29th. If your PC is up to date and has a genuine copy of Windows 7 or 8.1 installed, you should start seeing a Windows icon in the notification area (one of the icons near the clock), you can use this to reserve your upgrade to Windows 10.
As soon as Windows 10 becomes available you’ll be able to download and install over top of your existing install of windows, meaning you’ll lose no data or programs.
