Computer Locked – Login screen issues with Microsoft Windows

While I locked my machine I saw a login screen, I thought of testing it to find bugs which I love to do always.

Bug #1: It says press Ctrl – Alt – Del to unlock this computer

My view: Generally while speaking verbally we say press Alt [ plus ] Control [ plus ] Delete. I have seen people telling in this way. But I see hyphen which is also minus.

Bug #2: It doesn’t say Ctrl – Alt – Del has to be pressed in sequence as provided

My view: While I was in BWST – 2, Vipul Kocher talked about a cool point that is. Why do we enter username first and password next? What most of testers do not try, password first and username next. This gave me a test idea of trying out different combinations like,

Ctrl + Alt + Del = Works

Alt + Ctrl + Del = Works

Other combinations failed.

Why did Microsoft say Ctrl – Alt – Del but not Alt – Ctrl – Del.

Possible reasons

  1. They assumed people use Ctrl – Alt on the left hand-side of QWERTY keyboard
  2. May be test team did not find that Alt – Ctrl – Del works too
  3. May be they found it but did not report it
  4. May be Bill Gates thought, “Why would a user do it” or else he had explanation for that saying, “We have given flexibility” for the end-user [ My question is then why you have not mentioned it anywhere in Microsoft Operating system or Help & Support saying Alt – Ctrl – Del works too ]

Bug #3: The error message when I did not enter any password and clicked on “OK”

It said,

>> The password is incorrect. Please retype your password. Letters in passwords must be typed using the correct case <<

My view: When I did not enter any password why it is saying my password is incorrect when there is not even single character ( Even white space ) that I entered in Password.

Bug #4: If you look at the error message,

It says “Letters in passwords << This is supposed to be password and not passwords. Because I have a single password. There is also inconsistency within the error or alert message.

They say twice that, “The password is incorrect”. << Here they have used password and not passwords

“Please retype your password”. << Here they again say password but not passwords.

But,

“Letters in passwords must be typed in correct case”. << Here they use plural form which sounds weird and doesn’t make sense.

Bug #5: One more here after some time I found,

It says computer is locked & in the same dialog alert message it says,

Press Ctrl – Alt – Del to unlock this computer

I pressed it but it asked me for the password. When it said it will unlock on pressing Ctrl – Alt – Del why it did not unlock it? Sentence and wording used are not appropriate here.

Bug #6: Printscreen is disabled when computer is locked but not disabled on login screen after rebooting

Do you see inconsistency here? What was the purpose of keeping it disabled when computer was locked and enabled when computer was restarted or booted displaying the login screen?

Bug #N: There are many other bugs but I had stop my testing activity as I was interrupted with other work.

I love Usability :)

Note that these are obvious bugs that I found and you might have also found but did not know that it is a bug :)

Thanks for your time in reading this blog post with cool bugs of Microsoft. I would also love to hear your thoughts on these. You would want to say this is a bug or this is not a bug.

  1. Bug #4: If you look at the error message,

    It says “Letters is passwords <<

    Shouldn’t that be : “Letters in passwords” ?

    Good post Santhosh :)

  2. @Ajay,
    You are absolutely right. As I couldn’t take screenshot of that I typed the alert message text manually where I made a mistake of typing “is” instead of “in”. I have corrected it now. Thanks for pointing it out ( Good eyes ).

    Thanks,

    Good post and a good observation.

    Now, it doesn’t surprises me when I see the Win XP install media which is 500mbs and its SP3 is 324mb. Hope the SP4 would be a bigger one and resoles some of the Bugs that you have found.. Cheers…!!!

    I liked this observation. If you like to test usability testing why dont to try MS Word?(If not already tried)
