If you want, you can change the time limit on the restore function. Go to the Backup tab and you will see it. The restore option is in the Settings app under the Update & Security group of settings. When you need to restore the older version, copy this folder back to your Windows drive. If you want to be able to restore it after the 30 days, copy it to an external drive. When the 30 day time limit expires, this folder’s content is automatically deleted. This is where Windows 10 stores the restore image for your system. When you update Windows 10, a folder called Windows.old is created at the root of your Windows drive (usually the C drive).
