And they potentially have very different ideas of how things are laid out in memory or how different parts of the system communicate with each other (after all, making changes to that stuff is one of the main reason why updates are released in the first place).

And if those programs open Windows components they werenвЂ™t previously using - or potentially even if they use previously-unused functionality of the components they already were using - then thereвЂ™s suddenly a mix of old new Windows components (or even old and new parts of the same Windows component) in memory at the same time. Because those other programs already have some Windows DLLs loaded into memory, and those in-memory copies are the old versions.

Now letвЂ™s say that Windows Update finishes its update, and tells Windows to close its shadow copy - in other words, to write all its changes to the вЂњregularвЂќ version of the system, and let the other programs see them. That would have some performance impacts, but we could potentially do it. So weвЂ™d actually need to create two shadow copies at the same moment - one for Windows Update, one for everyone else. In the case of Windows Update, Windows would be making changes that it wouldnвЂ™t want the other programs to see, but those other programs would also be making changes (and potentially to the same directories, though hopefully not the same files). Remember that a shadow copy works on a whole volume, and divides it into вЂњthe contents of the volume at that momentвЂќ and вЂњthe changes since thenвЂќ. We could certainly create a вЂњreverse shadow copyвЂќ that works this way but thereвЂ™s another problem. What Windows Update would presumably want to do is the reverse - it would want to make changes to the Windows directory, while everyone else sees an unchanged version of it from the moment before the update started. The shadow copy is unchanging, and normally only one program sees it. So immediately thereвЂ™s a bit of a disconnect between how shadow copies work and what Windows Update needs to do. By using a shadow copy, a backup program knows that itвЂ™s capturing a consistent view of the system at one moment in time (the moment when the backup started). If, say, you were installing a program while the backup was going on, the backup might contain only half of the programвЂ™s files, with all sorts of bad results. A problem with Windows backups programs prior to the implementation of shadow copy was that the backup was sometimes inconsistent, because the backup contained the version of each file that happened to be present at the moment that the backup program got to it. Shadow copies are typically used for backup products. ThatвЂ™s because when one of these programs says вЂњGive me the data in file XвЂќ, Windows starts by reading the shadow-copy version of file X, but then checks to see if any changes have been made if so, those changes get applied before the data is returned to the copy. All the other programs donвЂ™t typically know that the shadow copy exists, and they see the changes made since the shadow copy was created. Typically, the program that created the shadow copy is the only one that sees its unchanging contents. So in other words, the volume is essentially split into two parts: one that holds the contents of the file system at the moment the shadow copy was requested, and one that holds all the changes that have been made since then.

While the shadow copy is active, writes to that hard drive donвЂ™t overwrite the existing contents of the volume instead, theyвЂ™re redirected to a special part of the file system. A shadow copy essentially lets a process take a snapshot of a volume (C:, D:, etc.) at any given instant. In order to explain why shadow copies donвЂ™t really help us, let me first explain what a shadow copy is.
