Vista - Sandboxie alternative 64 bit Home Premium?

Anyone know of any software that provides isolation to individually running programs similar to Sandboxie for Vista64?

I don't like to run virus shields. I'd rather run suspect programs in a cage. Anyone know something that works in 64 bit?

virtualbox might be what you are looking for, but im not sure if it supports 64bit yet. i got bluescreens installing windows 7 64bit on it.

I messed around with VirtualBox before. I didn't like the Browser Appliance or whatever it was since I had Sandboxie. I did manage to install a virtual Win98 but then I realized the entire supported file system size on Win98 was smaller than one of my downloads!
Things change too fast.

its shocking how advanced things have gotten over the last 10 years regarding computing, i remember having a win98 computer with a pentium 2 MMX, 32Mb of ram, it was blisteringly fast when i had it, but looking back, i feel a bit of a tit for thinking that lol. i now have 8Gb and a Q6600. its brilliant

Don't feel bad. My first PC was a Leading Edge Model D XT compatible. It ran an 8088, which was an 8 bit CPU that mimicked the 8086 16 bit chip. The default was 4.77 MHZ, but if you flipped the Turbo Switch(tm) in the back you got a rip roaring 7.16 MHZ

I'll say one thing for it though, I locked it up many times programming TSRs in assembler and just cycled the power. I didn't have a breakout switch. Worst that ever happened was I had to restore Dos sys files I think. You could pummel that hw all day long and it would still work.
