Maybe you should've put LMWTFY (Let Me Wikipedia That For You) and then provided the link.

I seem to remember Linus saying he didn't want LMGTFY posts.

I just though, LMWTFY posts would be regarded in the same vein.

NP .  I didn't take any real notice.  Enough to post (didn't take much I was at a loose end) but not enough to take any offense..

Shadow Copy is a feature of Windows that does a system backup and sores it on your system. It stores only the modified bits from system files.

This allows you to go back in time your system to under a failed Windows update, or you installed a software that crapped out your system.

To some extend you may undo a malware or virus infection, however, many of them corrupts the shadow copies, or clear them, so you have no restore points.

Restore Points from shadow copy can be corrupted and made unavailable if you use any defrag software that isn't the one built-in Windows, as Windows knows where the data is being stored on disk, and knows it's related to shadow copy, and won't try to move it, in thinking it goes somewhere else part of the defrag process.

In Windows 7, Shadow copy was extended to include personal files so that from the Properties panel of a file or folder, you can go back in time.

Windows 8 dropped that specific feature from Windows 7, and replaced with something more robust and can't be cleared, and transferable from 1 system to another, and file accessible, not get corrupted by defrag software. It is called File History. File history only works on separate drive partition or physical drive section locally, externally or on a network drive.

 Project much?

 

It doesn't mean I don't know what something is.  It could be that I do not regard myself as a teacher/wordsmith and I can't condense into a  shortish post the meaning of something in the same way that someone (maybe many) can in a full article so rather than attempt to rewrite the full meaning of something I link to an article were it is suitably explained in toto.
