This post will familiarize you with the error request process.
DISCLAIMER: If you do request an error correctly, I do not guarantee I will use it in an episode of Microsoft Sam reads Funny Windows Errors.
Onwards to the tutorial.
Go to http://atom.smasher.org/error/. This is the primary website generators. While there are likely others, less prominent generators may be on websites infected with malicious software. Type in the text for the title, message, and if applicable, buttons.
Generate the error. Scroll down to where it says "Copy this link to send this page to a friend" and copy that link.
Go to my YouTube channel. Click the About tab.
Click the "Send Message" button.
NOTE: If for some reason your YouTube account is not linked to a Google+ page, you cannot send me or anyone else a private message.
Paste the link in the message. Once that's done, send the message.
Alternatively, you may send an error request through my Facebook page. Errors submitted in the comments section of videos will not be accepted under any circumstance.
