In elevated mode: Find in your start menu, Right click your Command Prompt (MS-DOS Prompt) and select Run as Administrator.Click [Continue] button. I went to the root directory before typing the codes. Note, there is a space before the dash, then a letter follows.
Note: -section
-applicationPoolDefaults
This syntax:
c:\>%windir%\system32\inetsrv\appcmd set config -section:system.applicationHost/applicationPools -applicationPoolDefaults.processModel.loadUserprofile:false
