# title: Get-Sysinternals
# description: Downloads the current sysinternals from \\live.sysinternals.com\tools and then updates your path environment variable to include the location saved to. Along with that it sorts, and removes duplicate entries in the path variable. If you call get-sysinternals without any args the local directory will be systemroot\Sysinternals\ Otherwise, the files will be put in the specified path.
