I know that you can switch the ALT + Tab back to the classic style that you may be familiar with from Windows 7 by making a small registry tweak but before reading on and following my steps please understand I'm not familiar with your tech level and using Windows Registry Editor can be dangerous that can cause permanent damage to your system if used improperly. Also bleeping computer as well as myself wouldn't be responsible for damage if you follow the steps and something were to go wrong...
That is just a advisory I put on ANY post that includes registry play so please understand why I do it is because I've seen others use it and cause major damage.
- Launch Registry editor: Press Win+R keys on your keyboard, the "Run" dialog will appear. Type regedit without quotes and press Enter. Continue with the UAC prompt.
- Go to the following Registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
- Create a new 32-bit DWORD value named AltTabSettings and set it to 1.
- Sign out of your computer or reboot it then log back in
- Now try ALT + Tab to see if this has resolved your issue

Also if you're un-familiar with Registry Editor feel free to reference this page
Both above resources come from "Winaero.com" please be cautious when viewing their pages as some advise using "Registry Tweaker tools" and other tools to accomplish the registry change I have laid out... Be warned that most of those tools come packed with Adware/Malware so simply use the pages as references for my steps posted here if needed.
Please feel free to post your result if it worked or not so I can confirm more successful cases on this work-around.
