I've read conflicting information on this, so wanted to clarify the situation.
With Windows Vista/7, several third-party tools exist that can mount the contents of a Volume Shadow Copy (VSS) snapshot and allow a user to browse/copy the content; whilst this isn't a method for backups (these snapshots are stored on the same disk as the operating system), they are useful for recovering changed files if necessary. By default, Windows generates VSS snapshots automatically as part of the System Protection component; as long as System Restore is enabled, so-called "restore points" are created every several days, or when software/a Windows Update is either installed or removed.
As of Windows 8, however, my understanding is that this has now changed. Rather than the previous Windows Vista/7 behaviour of allowing users to browse Previous Versions of files/folders (which used VSS in the background), this has now been replaced by something called File History which can only be enabled if a second drive is connected to the system that the OS is running on. So, my question:
Does Windows 8/10 still create VSS snapshots in the background - and if so, what triggers the creation of them? Are the rules similar to that of Windows Vista/7 whereby snapshots will be created upon the installation/removal of software, or every couple of days? Is it possible for a user to manually create a snapshot via the Windows GUI?

File History allows the user to configure specific directories and/or files to keep backups of, which are then able to be seen/restored from via [File] Properties > Previous Versions. The single best system backup solution for Windows has always been, and continues to be, the native method Windows has always supported, WIM or ESD imaging viaImageXin Win <=7 orDISMin Win >=8 (see the Imaging section in this answer) – JW0914 Oct 30 '19 at 14:28
