It's hard to imagine I have managed to piss off 5000 posts on WF. I have been struggling with what to do this post on for the last couple of months. I didnt want to do the same old milestone post that everyone does, so I figured I would try something different. Besides I could never compete with some of those epic posts.
So what are we going to talk about here? With all the revelations that have come to note in the last year, privacy is the perfect topic. This post is by no means meant to be all encompassing. Its meant to remind you of things you forgot about, and hopefully show you a few new tricks. I would really love to see this turn into a conversation about ways to maintain privacy. Tips, tricks, tools, scripts, are more than welcome. Just because somethings may seem like beginner stuff to you, your WF brother may have never heard of it before. Well that's about it, here we go.

You can manage your Volume Shadow Copies by running an elevated command prompt (type command in WIN search box, right click, run as admin)
Here are the basic commands to see if you have VSC's on your machine

If you have nothing to hide, you shouldn't have anything to worry about.

Shadow Copy (also known as Volume Snapshot Service,[1] Volume Shadow Copy Service[2] or VSS[2]), is a technology included in Microsoft Windows that allows taking manual or automatic backup copies or snapshots of data, even if it has a lock, on a specific volume at a specific point in time over regular intervals. It is implemented as a Windows service called the Volume Shadow Copy service. A software VSS provider service is also included as part of Windows to be used by Windows applications.
Shadow Copy technology requires the file system to be NTFS to be able to create and store shadow copies. Shadow Copies can be created on local and external (removable or network) volumes by any Windows component that uses this technology, such as when creating a scheduled Windows Backup or automatic System Restore point.
A number of Microsoft Windows components have been updated to make use of Shadow Copy. Backup and Restore in Windows Vista, Windows Server 2008, Windows 7 and Windows Server 2008 R2 operating systems performs block-based backups when doing full system backups. The file backup feature also uses shadow copy but stores files inside ZIP files.
Shadow Copy - Wikipedia, the free encyclopedia
Volume Shadow Copy maintains snapshots of entire volumes. By default, it is turned on for your system volume (Cand protects all the data on that volume, including all the system files, program files, user settings, documents, etc.
It doesn’t matter how many times you overwrite the file, the shadow copy will still be there, safely stored on a hidden volume. A partial solution is to delete all the shadow copies (by choosing Control Panel | System | System protection | Configure | Delete) before you wipe the file. This prevents VSC from making a copy of the file right before you overwrite it. However, it is quite possible that one of the shadow copies you just deleted already contained a copy of the file (for example, because it had recently been modified). Since deleting the shadow copies does not wipe the disk space that was occupied by them, the contents of the shadowed file will still be there on the disk.
So, if you really wanted to be secure, you would also have to wipe the blocks that used to contain the shadow copies. This would be very hard to do, as there is no direct access to that area of the disk.
What you should know about Volume Shadow Copy/System Restore in Windows 7 & Vista (FAQ) | Trying To Be Helpful
You can manage your Volume Shadow Copies by running an elevated command prompt (type command in WIN search box, right click, run as admin)
Here are the basic commands to see if you have VSC's on your machine
Vssadmin List Providers: Lists registered Volume Shadow Copy providers. Windows Vista includes Software Shadow Copy Provider 1.0.
Vssadmin List Shadows: Lists existing volume shadow copies, the time the shadow copy was created, and its location.
Vssadmin List ShadowStorage: Lists the volume shadow storage space currently in use, the space that is reserved for future use (labeled as allocated), and the maximum space that might be dedicated. This space is used to store changes while a shadow copy is active. The following sample output was generated using a computer that currently had about 3GB of files stored in a shadow copy, but that might allocate as much as 6.4GB.
Vssadmin List Volumes: Lists volumes that are eligible for shadow copies.
Vssadmin List Writers: Lists shadow copy writers, which support communicating with the Volume Shadow Copy service to ensure that files are captured in a consistent state. By default, subscribed writers include an operating system writer, a registry writer, a WMI writer, and a search service writer, among others. SQL Server also provides a Volume Shadow Copy writer.
Vssadmin Resize ShadowStorage: Resizes Volume Shadow Copy storage. You can use this command to increase the maximum space that might be used by Volume Shadow Copy. Typically, this is unnecessary. However, if you discover that backups are failing on a computer because of an extremely high volume of changes during a backup, and Vssadmin List ShadowStorage reveals that the used Shadow Copy Storage space is at the maximum, you might be able to resolve the problem by manually increasing the maximum size.
