Story:

IIS on my development computer stopped working. I just installed the latest update to windows 10 and now when I try to start the "Windows Process Activation Service" I get an "Windows could not start the Windows Process Activation Service on Local computer. Error 15: The System cannot find the file specified" error.

Solution:

Navigate to:

C:\Users\All Users\Application Data\Microsoft\Crypto\RSA\MachineKeys\

find these 3 Key-files...

d6d986f09a1ee04e24c949879fdb506c_*

76944fb33636aeddb9590521c2e8815a_*

6de9cb26d2b98c01ec4e9e8b34824aa2_*

... then in Security-Settings:

  • first, you have to set your User as OWNER

  • close Properties Dialog - and open again

  • Then in ACL set "full controll" for SYSTEM

After that: WPA can be started...
