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 live.sysinternals.com/<toolname> or \\live.sysinternals.com\tools\<toolname>.
You can view the entire Sysinternals Live tools directory in a browser at https://live.sysinternals.com/.
