I'm looking forward to your feedback.

Btw., as a sidenote, are you aware that you can access the filesystem
underneath the volume shadow copy as well?

Try this (note the trailing backslash!):

  $ cd /proc/sys/Device/HarddiskVolumeShadowCopy1/
  $ ls

The only downside is that you can't cd into the root dir of the
shadowcopy by using a ".." expression:

  $ cd /proc/sys/Device/HarddiskVolumeShadowCopy1/Users
  $ cd ..
  /proc/sys/Device/HarddiskVolumeShadowCopy1: Not a directory.
  $ cd ../
  /proc/sys/Device/HarddiskVolumeShadowCopy1: Not a directory.

Here the path handling strips off the trailing backslash and what's
left is a block device called /proc/sys/Device/HarddiskVolumeShadowCopy1.
With that in mind, it's quite usable, though.
