If you are looking for Windows 11 instructions, you can find these here.
Windows 10 analyses various personal data. Data affected here are for instance your e-mail address and contents of e-mails received and sent out, personal interests and favourites, purchase and payment data, your personal address book, etc.
Many of these data are also transmitted to Microsoft. Most of these data transmission mechanisms however can be switched off. On the one hand, you should consider certain criteria when first installing Windows 10; on the other, various settings can still be adjusted afterwards. Our instructions are meant to assist you with selecting the correct settings and to protect your data and all your private information in the best possible way.
We have tried to draw up as universally applicable a set of instructions for private users as possible. Nevertheless, the individual configuration options and settings may differ in specific cases. These instructions refer to the options available as at 8 February 2025.
Settings during Windows 10 installation
During any Windows 10 installation, you can already make some decisions regarding data protection. You will be asked how extensive you would like the amount of diagnostic data sent back to Microsoft to be. At this point, you can only choose between «Include as an option» and «Required only». To avoid Windows sending too many data to Microsoft unintentionally, please select «Required only».
After installation, you can personalise certain settings. Wait until Windows has finished installing, and then change your settings.
Settings after Windows 10 installation
Should you already have installed Windows 10, you can subsequently adjust settings in Windows. You will find the relevant menu under Start (Windows logo) > Settings (cog) > Privacy.
General
To protect your device against definite identification based on an advertising ID allocated by Windows, switch the first option «off».
You should leave the second option «on». This way, you ensure that websites are displayed in the language set as the Windows system language where possible.
The third option serves for local improvement of Windows and be left switched «on». Windows can launch apps in frequent use by you more quickly this way.

| Option | Our recommendation |

Location
Location is used by your device to send the location where you are using it to Microsoft. Location detection should be switched off.
If location detection is active, organizations other than Microsoft can establish your location, too – in particular if you allow apps to access your location.
Scroll down a little bit, and by clicking on the «Delete» button any location data potentially submitted so far already can be removed from your device. Whether Microsoft will also then delete them, is not clear.
Should you have location activated anyway, you can enable or disable location detection for each of your installed apps individually as needed. Your location data will then potentially be passed on to the provider of all relevant apps you activate this for.

Background apps
Microsoft terms a program a «background app» if it always remains up-to-date, even if you are not actively using it. Withdrawing this right from an app can help you save power.

| Option | Our recommendation |
|---|---|
| Background Apps | Depending on your requirements |

Data protection dashboard
To guarantee the transparency of all data collected, Microsoft offers a data protection dashboard which lists all information stored. You can also delete these details as long as you are logged in via a Microsoft account. Your data protection dashboard is available via «Privacy», «General», «Learn more about your privacy options» or via this link: https://account.microsoft.com/privacy
Microsoft account
You can use a Microsoft account to log into several Microsoft services. Amongst other things, this includes the online Office 365 software, the OneDrive cloud service, Teams and phone service and the Xbox Live games platform.
The advantage offered by a Microsoft account is that you are able to log into all Microsoft services using just a single e-mail address and password. You therefore don’t have to set up and remember several different user names and passwords. In addition, a Microsoft account facilitates the use of multiple Windows devices: Your activity history, cache, OneDrive plus various settings such as WLAN connections are automatically synchronised on all devices on which you log into your Microsoft account.
The drawback of a Microsoft account is data protection issues. You should be aware that Microsoft also collects data via your account: Locations, calendar entries, search queries, your browser history etc. These data are then for instance used to display suitable, personalised advertisements to you. If you don’t want this, it is better to use a local account.
