Windows Sandbox
Did you ever hear of Windows Sandbox... probably not, right?
Windows Sandbox is a more or less new feature which was released with build 1903 of Windows 10. It can be installed via the control panel by adding Windows features.
Once installed you need to reboot the computer. After the reboot I light weight VM is available in your start menu called Windows Sandbox. Inside this sandbox you can test downloaded software, executables or your own code. This is very useful before you deploy new software and do not want to build new full size VMs with Hyper-V all the time. Getting it started took less than 5 minutes.
After finishing your tests, you can shutdown or close the sandbox and all data inside is gone and you can start from scratch for any new software/test scenario.

Guess it will save some time and make testing a bit easier.
