Process Monitor in Windows 10 error

If when running Process Monitor in Windows 10 you get the error 

   Unable to write PROCMON23.SYS.

   Make sure that you have permission to write to the %%SystemRoot%%\System32\Drivers directory.

then you can follow the suggestion from Error from Process Monitor: “Unable to write PROCMON23.SYS”: "go into C:\Windows\System32\drivers and rename procmon23.sys to something else, then try to enable boot logging from options menu again".
