Info

The password for Century10 is the 161st word within the file on the desktop.

NOTE:
– The password will be lowercase no matter how it appears on the screen.

Theory

To get the password we have to get the 161st word in a text file, it's really simple to do something like that, we just need to have a code that replaces all first 160 words with nothing. And so we get this command, shorter than the last, it first reads the file and then replaces all words with whitespace characters, which are literally nothing, so esentially it's just deleting those words. Then it multiplies the whitespace characters by 160, to replace all first 160 words and then leaving us with the password 161st word at the beginning of the response:

(Get-Content text.txt) -replace '^(\S+\s+){160}'
dir

Solution

Now that we are in the desktop, first we'll use dir to know the name of the file and put it in the command:

PS C:\users\century9\desktop> dir


    Directory: C:\users\century9\desktop


Mode                LastWriteTime         Length Name
----                -------------         ------ ----
-a----        8/30/2018   3:34 AM           2131 Word_File.txt

PS C:\users\century9\desktop> (Get-Content Word_File.txt) -replace '^(\S+\s+){160}'

And that's the password! Now we should be good to go to the next level. (Remember, it's the first word.)
