Final answer:
Having CAPS LOCK activated affects the Windows sign-in process because passwords are case-sensitive. Thus, the correct answer is "Yes, it affects the login process" (Option A).
Step-by-step explanation:
If you are attempting to sign in to Windows, it does matter if the CAPS LOCK light on the keyboard is activated. Windows passwords are case-sensitive, which means that if the CAPS LOCK is on, any lowercase letters you think you are entering will actually be entered as uppercase letters, and vice versa.
For example, if your password is "Password123" and CAPS LOCK is on, you might enter "pASSWORD123", which the system will recognize as incorrect. Therefore, always ensure that CAPS LOCK is off when you enter your password unless your password specifically contains all uppercase letters. Consistently verifying the status of the CAPS LOCK can help prevent unnecessary login issues and save time.
Thus, the correct answer is a) Yes, it affects the login process.
