I have been working at Abacus Computer Service GmbH since 2017 as a specialist in computer system interaction. Mainly I deal with Windows operating systems. These are Windows clients and Windows Server 2003, 2008, 2012, and Windows Server 2016 for examples. This is our top priority for our customers and we support them. In my spare time there is only Nethserver as server operating system. It’s stable, safe, fast and does not have many bugs.
