Word Mangling/Wordlist generator

Hi There,

I'm trying to crack a lost password. I think I know what it is, but must have originally entered it incorrectly as it is not working. Is there a way in Hashcat to enter the password and have Hashcat mangle each letter, misspelling it. 

I have tried to generate a wordlist of misspelled words but Crunch doesn't seem to work for windows 10. If this is not possible in hashcat can you recommend a wordlist generator that can do this in windows

I'd appreciate your help.
