It requires neither the disabling nor blocking of functions available to Web sites through the browser. However, whether these changes are harmless or harmful, they do, in fact, happen to your computer system. Most of the time, these changes are harmless, like recording the addresses of websites you have visited (and when), so the browser can help you complete a web address that you type in. When you browse the web, changes occur to your system.

Not a major problem for me but a bit annoying.Sandboxie lets you run programs in an isolated space, which will prevent them from making permanent changes to other programs and data to your computer. Everything else stays open but the explorers that were open are all gone and 1 or 2 utility programs also are gone (one is to show current month calendar when I hover mouse cursor over clock). I can have a few others running but when I get ready to run a new instance of Firefox in a sandbox I get a message that explorer has crashed and lose all my open explorer windows. Perhaps a conflict with one of the other utilities/drivers/programs running in the background. One minor problem is it seems to cause my explorer to crash every now and then when I try to invoke a sandbox on my 64-bit system (Win 7). I'm glad I paid to have use of all its features and can't imagine being without it. Although Shadow Defender does take up a small amount they seem to have some algorithm that prevents disk usage from becoming excessive.

The 'free' programs will 'eat up' your disk space and some change your MBR. Deep Freeze was my favorite but they have an annual fee now. Although not free it more than makes up for the cost by being low maintenance. My preferred program to avoid problems you described is Shadow Defender.
