Windows and Linux side by side

Windows: Windows 11 excludes processors from before about 2018 – however well the computer runs.

Linux: Runs on computers that are supposedly too old for Windows 11.

Windows: Ads in the Start menu, switched on by default.

Linux: No ads. Anywhere.

Windows: Office costs money – a subscription every year or a paid licence.

Linux: LibreOffice is free and opens Word and Excel files.

Windows: Almost every industry program exists for Windows.

Linux: Adobe and some industry programs aren't available for Linux. There are free alternatives for much of it; otherwise Windows stays alongside.

Windows: Updates force restarts – you can only postpone them for so long.

Linux: Updates run in the background. You restart when it suits you.

Windows: A new computer can normally only be set up with a Microsoft account.

Linux: No account, no sign-in with the vendor.

Windows: Windows sends usage data to Microsoft – and you can't switch it off completely.

Linux: No usage data sent to a vendor.

Windows: Copilot and other AI features come built in – nobody asks you.

Linux: No built-in AI – only what you install yourself.

Windows: Almost every device comes with a Windows driver.

Linux: Most devices just work, no hunting for drivers.

Bottom line: For most people Linux is all they need. And where it isn't, Windows stays alongside.

Linux adapts to you

Windows comes in one form. Linux comes in many – lean and light for older computers, modern and versatile for newer ones. We choose the one that suits you together.

Screenshot: Linux with the Xfce desktop, file manager showing the personal folders — **Lean and classic** (Xfce) – runs well on older machines too.

Screenshot: Linux with the KDE Plasma desktop, file manager showing the same folders — **Modern and versatile** (KDE Plasma) – for newer computers.

Two real screenshots, two of many options. Your programs and files are the same in each.

But what about …

… online banking and tax filing?

Whatever runs in the browser runs on Linux too: bank, ELSTER, shopping, video calls.

… games?

Many Windows games run through Steam – no Windows needed.

… not getting on with it?

Start menu, taskbar, folders – you know them already. And until you decide, Windows is still there.

The three-phase model

No data risk. You decide at every step.

SoftwareYou stay on Windows and already get to know the new programs there. I back up your data first.
Test environmentLinux is added in parallel. Your data comes along, and Windows is always one restart away.
Your decisionWindows goes or stays for a program. We clear up your last questions, and you're done.

At most €199 of labour per computer until your switch is complete. Questions by e-mail are free, as always; parts only if needed. If it takes longer, that's my risk. All about the three-phase model →
