A computer Sandbox is newer technology that is not very well known, but, it can be quite useful in many situations. By using a Sandbox utility, you can place your computer in a protected state where you can try some rather risky things on your computer and not have your computer damaged in the trials. Once you place your computer into Sandbox mode, you can safely run anything on your computer, knowing that all changes to your hard drive will not be permanently made to your computer. While in Sandbox mode, your computer runs as if all changes to the hard drive were actually made to your system. But, at the end of using the Sandbox, you can throw away these changes, putting your computer back exactly the way it was before entering the Sandbox.

Letís take a look at some real life situations to better understand the benefits of using a Sandbox utility.

Installing New Software
Everyone knows that when you install a new software product on your computer, parts of the product are placed all over your computerís hard drive. Entries are made to the Windows Registry, special supporting files are place in certain directories of the operating system, and other shortcut and setting files are scattered in various places on your hard drive. These are in addition to the main folder that is installed on your hard drive with the software programs. Most software will uninstall easily, but often pieces of the product are left behind on your hard drive. These leftover pieces of orphaned software can build up and slow down your computer. Some software products include hidden viruses or other bad programs as you install them. The end result is that installing new software on your computer can be a risky thing to do.

Using a Sandbox to install and test new software is a much better approach. With a Sandbox, you put your computer in Sandbox mode before you downloaded and installed the new software. Since the Sandbox lets you use the newly installed software just as if it had been permanently installed on your computer, you can run the new software to try it out and see if you like it. You can also run virus utilities to see if the installation gave you a virus you were not expecting. If you find viruses on your computer or just decide you do not like the newly installed software, you can get out of the Sandbox and throw away all traces of that software product and any hidden virus that came with it.

Letting Others Use Your Computer
Another reason to use a Sandbox is to let others use your computer. Other users may change your computer to match the way they like to use computers. For example, many of us have grandkids that come to visit and want to play on our computer. They may download games they like, change your wallpaper and default font sizes. They may pick up viruses in the process of getting your computer changed to their needs. When they leave, your computer no longer is the same as it was before they arrived. It may take you days to get it working again like you want it to. With a Sandbox, you can place the computer in Sandbox mode before they arrive and then let them play on your computer to their hearts content. When they leave, you simply exit the Sandbox and throw away all changes that they made to your computer. It is instantly back the way it was before they started to use it.

Computer Labs and Classrooms
User groups that have computer labs or classrooms have a similar situation. The classroom computers are setup carefully by the instructors before the class begins. Once the students have used the computer throughout the day, the computers are different and modified from what they were in the beginning of the day. This may cause problems for the students that follow them, so the instructors will often restore the computerís hard drives to put them back to normal. With a Sandbox, this long restore process is not needed. Instead, put the computers in Sandbox mode at the beginning of the day before the students arrive. Then at the end of the day, exit the Sandbox and throw away all hard drive changes made by the students. The computers are quickly returned to their normal state as you exit the Sandbox.

Browsing the Internet
Much of the Spyware that you pick up on your computer comes from simply browsing the internet. Some web sites are designed so that simply passing your cursor over a part of the screen is enough to activate a download of Spyware to your computer. Not only that, but your privacy is at risk when you browse the Internet. Windows automatically saves all of the places you browse to and all of the screens you see on the Internet. Browsing the Internet in a Sandbox is a much better approach. Place your computer in Sandbox mode before you start to browse the internet. Then browse all of the sites you want to. When you are done browsing the internet, exit out of the Sandbox and throw away all Spyware and traces of web sites you may have visited.

We offer three excellent Sandbox products that you may want to use on your computer. Letís look at each of these briefly to help you decide which one would best meet your needs.

StorageCraft ShadowSurfer
The smallest and least expensive Sandbox we offer is ShadowSurfer by StorageCraft Software. This product is the quickest product to install and the easiest product to use of all of our Sandbox products. With ShadowSurfer, all changes to your hard drive are always thrown away when you exit the Sandbox, which is what you want in most cases anyway. This excellent product runs on Win2000 and WinXP systems and is available from us at the discount price of just $20. This is an excellent beginning Sandbox product for most home users.

Acronis True Image 11 Home Try&Decide
The next step up in ability and price is a feature that Acronis has added to their new True Image 11 Home backup utility. This feature is called Try&Decide and it is a Sandbox feature built into this award winning backup utility. Try&Decide requires that you create and use the Acronis SecureZone on your hard drive to contain the temporary changes to your hard drive. When you exit the Sandbox with this product, you can choose to keep all changes to your hard drive or throw them all away. This excellent product runs on Win2000, WinXP, and WinVista operating systems and is available from us at the discount price of just $29 for a download or $33 on a CD. This is a very good Sandbox feature that comes with an outstanding backup utility.

StorageCraft ShadowUser Pro
The most advanced Sandbox utility we offer is ShadowUser Pro by StorageCraft Software. This is a professional-level Sandbox product that has many options and features to it. With this product, you can password protect the controls of the Sandbox, so that nobody can disable the Sandbox unless they know the password. Perhaps the biggest differences between this product and the other two Sandbox products is that you can pick and choose what files to throw away and what files to keep as you exit the Sandbox. This top of the line Sandbox product runs on Win2000 and WinXP operating systems and is available from us at the discount price of $47. This is the product you should use if you are running a public computer workstation that needs tight controls.

A Sandbox offers you a new way to protect your computer from damage from the software you install or access on the internet. It also keeps your hard drive safe from damage caused by others using your computer. The selection of Sandbox products we offer lets you pick and choose which one is right for your needs.
