PFUtil in Tools is architecture dependent

[hoyosjs]

Must find a way to either fetch it on the run, provide instructions on where to find it

[hoyosjs]

Currently can be worked around:

• Check HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\BuildLabEx to get the build version. It probably looks something like 14393.1358.amd64fre.rs1_release.170602-2252
• The executable can then be found, for the given example, at:
  \\winbuilds\release\RS1_RELEASE\14393.1358.170602-2252\amd64fre\bin\tests\superfetch\unittest\pfutil
  Replace rs1_release with the OS release, the number with the number sequence in BuildLabEx and amdfre with whatever comes before the OS release.
• Copy the binary into the tools folder.
