近日，COMODO出品了类似影子系统的的软件，看来COMODO真是要全面开花了。
Hi Guys,
We would like to announce that COMODO DiskShield 1.0.0.7 BETA is available for download and testing.

What is COMODO DiskShield?
----------------------------------------

COMODO DiskShield is a disk virtualization software which could protect your computer configuration instantly by turning the disks into virtual disks. With CDS, all the changes made to a disk, such as copying, deleting files/folders, formatting the disk etc. are going to be temporary.  All the changes will be eradicated when you restart the PC.

Why would you need such a product?
----------------------------------------------------

- because you don't want any changes to be made to your PC,
- because  you want to let your kids or friends mess around with your computer,
- becaue you want to browse the internet and go anywhere you like and not worry about consequences,
- because you are an educational institituion and sick and tired of support costs because users mess up the PCs,
- because you are a business and want your PCs operating at max without any changes,
- because you have an adequate imagination to find a use for it
