The SysInternals suite has been upgraded again. Windows Sysinternals: Documentation, downloads and additional resources
It also includes a live version (I've not tried them yet).
Sysinternals Live is a service that enables you to execute Sysinternals tools directly from the Web without hunting for and manually downloading them. Simply enter a tool's Sysinternals Live path into Windows Explorer or a command prompt as http://live.sysinternals.com/<toolname> or \\live.sysinternals.com\tools\<toolname>.
