Here’s what you need to know: if you have Windows 7 or Windows 8, the new version should integrate seamlessly without preventing access to any of your old files or settings. In other words, you should be able to upgrade to Windows 10 without losing applications, games, documents, pictures, and anything else you’re keeping on your hard drive. The process can be risky, however, if you don’t have much experience with operating system upgrades or if you’re running an older computer.
