Microsoft has made the task easy courtesy the Get Windows 10 tool that appears on all copies of Windows 7 and 8.
With Windows 10 coming on July 29, you'll want to make sure your PC, applications and various devices will all play nice before you reserve and upgrade. Fortunately, Microsoft has made it easy to do within the Get Windows 10 tool that appears on all copies of Windows 7 and 8.
Upgrading your copy of Windows to 10 should be seamless, but you want to make sure set up is actually ready beforehand. That new Windows icon down in your system tray will let you do more than reserve your copy of Windows 10 for free. As Fatima Wahab at AddictiveTips points out, it can also check your whole system to make sure everything is all set for the upgrade. It's pretty simple to do:
Click the Get Windows 10 icon in your system tray in the lower-right section of your desktop.
Click the hamburger menu in the upper-left corner.
Under "Getting the upgrade," select Check your PC.
If you're all set and ready for the upgrade when it comes, you'll be given a good to go message. Otherwise, you'll see a list of devices and apps that aren't supported.
Device issues could mean a monitor won't display properly at the highest resolution, or some speakers won't be able to play audio with the upgrade. Apps that are listed as unsupported will need to be uninstalled before you start the upgrade process. Of course, a driver update or patch install may fix those issues as well, so check again if you can find updates.
