Enabling window switcher in Ubuntu Budgie 17.04

I have Ubuntu budgie 17.04 (budgie-desktop 10.2.9). While pressing Alt+Tab to switch between the windows, the windows are switched randomly and I am not able to select which window to shift.

This feature was available in Ubuntu 16.04 but not in Ubuntu-budgie-17.04.

How to resolve this?

Not literally an answer to your textual question, but an answer to what you refer to in the image:

Window Previews

In the meantime, Ubuntu Budgie got his own Window Previews (17.04 >):

Usage is simple: after adding the applet to the panel, simply

• press Alt+Tab to get an overview of all windows (on current workspace), or
• Super+Tab to get an overview of all windows of the currently active window's application.

Simply Tab will subsequently browse through the overview.

Installation

...is best done from Budgie Welcome > Install Software > Budgie Applets

This is the hopeful solution to the problem. Thanks to @Dustin Krysak and @David Mohammed of Ubuntu-budgie community...!

• Go into the budgie-welcome application, ensure that the backports PPA is enabled. Then update. This feature was re added in Budgie 10.3.

or

sudo add-apt-repository ppa:ubuntubudgie/backports

• Then

sudo apt update

&&

sudo apt install budgie-desktop budgie-indicator-applet

Log-out and Log-in.

If the above steps donot work.....then...

sudo apt update

&&

sudo apt dist-upgrade

It will upgrade the system to latest version of budgie-desktop. The switcher feature was added in version > 10.3.*
