System Requirements, Installation and Registration


First things first: If you haven't already performed a full backup of your Windows partition recently, then I would strongly recommend for you to do so before installing Shadow Defender (or any other software for that matter). There is always the possibility that a new program may be incompatible with your individual configuration. Backing up now could save you from having to troubleshoot problems later on. Basic backup tips have been provided within our LV/IRS technology introduction.


Minimum System Requirements:


Operating System: Windows 2000 / XP / 2003 / Vista / Windows 7 / Windows 8


Memory by OS: 2000: 128MB, XP: 256MB, 2003: 256MB, Vista: 512MB, Windows 7: 1GB, Windows 8: 1GB (NOTE: these are the minimum RAM requirements. It is best to have at least 4GB of installed RAM before using the Shadow Defender RAM Cache option).


Disks: 3 MB for program files, 10MB or more free space for each partition in Shadow Mode.


Installation and Registration:


Installation takes mere seconds, depending of course on the speed of your system. When it completes you will be asked to restart your computer. The program doesn't add any boot sector drivers, which is a good thing in my view. After rebooting there will be a yellow Shadow Defender icon added to your system tray. Double-click on it and the registration prompt will come up.


Registration is very straight-forward. The program is fully functional as a 30 day trial with all of its features fully unlocked. If you have already purchased a license you can enter the serial number at this point. There is no hardware fingerprinting involved and the program won't ask you to access the Internet in order to register. In fact, I have been using SD for a long time now and it has never tried to go online, a huge plus in my book.


Once you have entered the serial (or chosen the trial option), the main SD window will come up, as below.




This is the System Status screen. You can select any of your volumes from the drop-down list on top, to see current information about them. If your disks are split into multiple partitions, then each one of those partitions will appear as an individual volume on this list. SD can protect all disks connected to the system, provided of course that its protection module (which is called Shadow Mode) is enabled for them. This includes all external disks that are currently plugged in; things like eSATA, firewire, and USB disks, as well as USB flash drives.


SD works at sector level, using RAM or each protected partition's free space for its virtualization cache. As a result you won't be able to see the buffer itself as an expanding file in Windows Explorer, as is the case with other LV applications which operate at file system level.
