Can you believe it? Windows 10 has been out for almost two years now, with no fewer than two major updates already issued under its name.
If you are still running Windows 7 or 8.1 and contemplating on upgrading to Windows 10, you may have missed out on a free upgrade since Microsoft stopped its free Windows 10 update program last year. The only way to upgrade your Windows 7 or 8.1 machine now is by shelling out cash for a Windows 10 Home or Pro license.
If you are a little apprehensive and worried that you might not like Windows 10 (click here for the 10 reasons not to switch to Windows 10), fret not. If you are within 30 days of your upgrade date, Microsoft included a way to roll back to Windows 7 or Windows 8.1 if you're not satisfied.
In Windows 10, rolling back to a prior installation of Windows 7 or 8.1 is easy and straightforward. When you update, Windows 10 actually stores a copy of your old Windows version in a folder called Windows.old. This makes the 30-day rollback window possible, so if you are planning on rolling back, please don't delete this folder.
