Hello, i tryed your solution but i don't have admin rights on my work computer, so i put the entry in HKEY_CURRENT_USER\Software\Classes*\shell\MakeMD5\command, it appears all right in context menu but upon clicking I get the following error : "Windows Cannot Access the Specified Device Path or File"
But on the file i right click "MakeMD5" the rights are all good, it's a file i created myself. i really don't get the error.
I tried to add another entry : HKEY_CURRENT_USER\Software\Classes*\shell\Npp++\command, with the value "C:\Program Files\Notepad++\notepad++.exe" "%1", and it's working perfectly
If someone can spare any help?

In Computer\HKEY_CURRENT_USER\Software\Classes\*\shell\MakeMD5\Command, I added the following value:
cmd /s /c pushd &(call certUtil -hashfile "%1" MD5) > ""%1"-Hash (MD5)".txt

Tested this to be working for an admin account. First, try this one to make sure there weren't any simple typo mistakes.
