An IPv6 is a preferred protocol over IPv4 in modern Windows and Linux systems.
In Windows, you can ping IPv6 addresses using a standard ping command.

In Windows you can easily get a list of installed apps with the installation dates through a “Programs and Features” (press ⊞ Win + R to start the “Run” dialog and type in appwiz.cpl and click “OK”).
To get a history of uninstalled programs is a bit more challenging, but is still possible using an “Event Viewer”.
In the “Event Viewer” we can list the changes made by an MsiInstaller – the tool that Windows uses for any installations and uninstallations of applications.
Additionally, we can filter out that list by the event ID 1034, that exactly corresponds to the program uninstallation events.
Below you will find how to check the uninstalled programs history in Windows and how to find out who has uninstalled a program and when. (more…)
