Kindly help me with two users account setup [Win 8.1 Pro]

Hi, I was a Windows 7 user and yesterday I installed Win 8.1 Pro, which I purchased almost a month ago, just didn't have the time to install (it was better that I didn't have any time) and since then I can't figure out lot of things, one of which is really disgusting. See that my mom and I use the same laptop, she uses it on morning and I at night. And thus I created two user accounts, for example mine is A and my mom's is B. Now when I turn on the lappy it goes straight into my account, without even asking to which I want login! Where on Windows 7 after the welcome screen always there was an option of two accounts, but story has changed. So what should I do to get it back like it was on Seven? I just want each time I reboot the machine there must be an option of both accounts, and I will choose where I wanna login.
PS: Both accounts of my mom and mine are set as admin.

Kindly help asap, she is an amateur and she gets confused when the lappy goes straight into my account.

Thanks.

Show all users is the one you'd want. Also, passwords often help solve the issue as well, and are recommended, especially for people with admin rights, because malware may be able to install without your consent, and passwords put a wall up against this.
