Thinking about upgrading to Windows 10? You probably want to know what programs and data you'll be able to keep. There's an easy way to check.
According to Microsoft, if you're upgrading from Windows 7, Windows 8, or Windows 8.1, you'll be able to keep your Windows settings, personal files, and most apps while upgrading your existing installation. Windows Vista users, however, will have to do a clean install.
If you want to know exactly what apps--and devices on your computer--might be problematic, head to the Windows 10 Upgrade Advisor.
Look for the Windows logo (it says "Get Windows 10") in the system tray. That takes you to the Get Windows 10 app, which lets you reserve your free upgrade copy by entering your email address.
To check for compatibility issues, in that same window, click the menu icon in the top left, then the "Check your PC" link.
When I ran the check, I learned that I might have problems with Bluetooth Hands-free Audio and avast! antivirus, and some drivers would need to be reinstalled after the upgrade.
For some compatibility problems, it's a matter of outdated drivers, so you can try updating these and then check again. Incompatible programs will be removed during the installation.
Otherwise, if you don't get any compatibility warnings, you're good to go and can just sit back and wait until July 29th.
