What Windows freeware adds powerful "phone Susan" & "vipw" commands?
a. Start Run phone susan {enter} == outputs Susan's phone number
b. Start Run vipw {enter} == decrypts an encrypted password file

This is a common need that everyone can benefit from your solution.

More detail:

1. Start Run vipw
The goal is that the passwd.txt file is an encrypted plaintext file
containing whatever data you want to put in the cleartext file, where, for
this example, passwd.txt contains passwords that you wish to keep handy but
which you wish to keep encrypted until you need it.

2. Start Run phone Susan
The goal is that the phone.txt file is a plain text file containing as many
lines as you want which contain the case-insensitive characters "susan" in
them (essentially it's a "grep -i susan" command).

Note: It's not at all hard to get any command to work in the "Start Run"
box if we simply set up an "App Paths" "exe" key:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\vipw.exe
Where the value of the "vipw.exe" key is, oh, say, "C:\path\command.bat"

The question is what "command.bat" will do these commonly needed tasks?
A. Decrypt & open a given plain text file (after entering the password)
B. Grep a given plain text file for the given keywords

What I'm not asking for:
a. Cygwin (because it's too complex)
b. Win10 Bash Shell (same reason as above)
c. Any solution that won't work from a single "Start Run" command.
(i.e., we don't want to pop up a complex GUI like Veracrypt is)
