As of 15.2.2019 you may notice that Microsoft software has been removed from Kivuto webstore, and the following announcement appears:
“The Microsoft Imagine program is now Microsoft Azure Dev Tools for Teaching. To access, please go to https://aka.ms/devtoolsforteaching and sign in using your username. It may ask you to create a Microsoft Account if you do not have one already.”
Microsoft products are now only available through Microsoft Azure Dev Tools for Teaching. After completing the signup using your JAMK credentials, you can browse available software (possibly) under Home -> Education -> Software.
VMware products are still available through Kivuto Webstore.
