Attach VHD
Attaching a VHD activates the VHD so that it appears on the host computer as a local hard disk drive. This is
sometimes called “surfacing a VHD” because the VHD is now visible to users. If the VHD already has a disk
partition and file system volume when you attach it, the volume inside the VHD is assigned a drive letter. The
assigned drive letter is then available for use, similar to when you insert a USB flash drive into a USB
connector. All users (not just the current user) can use the attached VHD in the same way they use other
volumes on local physical hard disk drives (depending on security permissions). Furthermore, because you can
attach a VHD that is located on a remote server message block (SMB), you can manage your images
remotely.

Once attached the single file can be restored.
The other answers are overkill or replace all filesnot just the one required.
What is system protection?
System protection is a feature that regularly creates and saves information about your computer’s system files
and settings. System protection also saves previousversions of files that you’ve modified. It saves these files in
restore points, which are created just before significant system events, such as the installation of aprogram or
device driver. They’re also created automatically once every seven days if no other restore points were created
in the previous seven days, but you can create restore points manually at any time.
System protection is automatically on for the drivethat Windows is installed on. System protection can only be
turned on for drives that are formatted using the NTFS file system.
There are two ways that you can take advantage of system protection:
If your computer is running slowly or isn’t workingproperly, you can use System Restore to return your
computer’s system files and settings to an earlier point in time using a restore point.
If you accidentally modify or delete a file or folder, you can restore it to a previous version that’ssaved as
part of a restore point.
