Using a genuine, licensed Windows system or a Linux distribution with an LTS (Long Term Support) release is primarily a matter of security. Genuine systems receive regular security patches directly from the manufacturer – Microsoft or Canonical – protecting the user against new vulnerabilities and exploits. Unofficial, modified versions of Windows (so-called “light” builds or activators) may contain hidden malware, backdoors, or modified system components that are difficult to detect even by professional antivirus tools. In the case of Linux, LTS versions guarantee support for 5 years (and in the case of Ubuntu, up to 12 years under the ESM program), ensuring a stable and predictable operating environment without the need for frequent system updates.
The second argument is software stability and compatibility. Genuine systems are tested by their manufacturers for compatibility with a wide range of drivers, applications, and business services. LTS versions of Linux are particularly valued in server and enterprise environments precisely because they offer a proven, unchanging kernel throughout the support period—without surprises resulting from aggressive updates. Using pirated Windows exposes the user not only to legal risks but also to a lack of access to updates and official technical support. In an era of growing cyber threats—including rowhammer attacks on GPUs and exploits bypassing the IOMMU—having an up-to-date and trusted operating system is the foundation of a secure IT infrastructure.
