You have backslash (\) characters in the string.  These are used in
Python (and many other languages) to handle special characters that are
otherwise hard to type directly.  For example \r is the carriage return
(enter) key.  To enter a literal backslash, you use a pair of them (\\).

The simpler alternative is to use a raw string.  By placing r before the
quote you can disable the special backslash processing.
r'SOFTWARE\Microsoft\Windows NT\CurrentVersion\WinLogon'+'\\' == 'SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\WinLogon\\'

NOTE that a raw string MUST NOT end with a backslash character!

Python is simply providing a means to use functions provided by
Microsoft.  You need to use the Microsoft documentation while making
allowances for the fact that the expected language is probably C++.
