Most people do not realize that Windows collects a surprising amount of data about them every single day. From the websites you visit and the apps you use to your location, typing habits, and even your voice commands, Windows has numerous built-in features and settings that silently gather information about you in the background and send it back to Microsoft's servers. This does not necessarily mean Microsoft has bad intentions, as much of this data collection is used to improve products and services, but many users simply prefer to keep their personal information private and under their own control. The good news is that you can significantly reduce or even stop most of this data collection completely for free without any technical expertise. Here is a complete guide on how to stop Windows from spying on you.
Disable Telemetry and Data Collection (O&O ShutUp10)
Windows has several built-in mechanisms for gathering information about how you use your PC, how it performs, and any errors that occur. While some of this is useful for improvement, it also feels like intrusive spying.
The Solution: Use O&O ShutUp10. This free tool provides a clear, simple interface that allows you to disable dozens of Windows features with a single click. It's the most comprehensive and popular tool for this purpose.
Turn Off Diagnostic and Usage Data
One of the biggest sources of data collection in Windows is the diagnostic and usage data setting, which by default sends detailed information about how you use your computer directly to Microsoft. To reduce this, open the Start menu and click on Settings, then go to Privacy and Security, and select Diagnostics and Feedback from the list. Here you will find a setting called Diagnostic Data and you should switch it from Full to Basic or Required Only, which is the minimum amount of data Windows is allowed to collect. On the same page you should also turn off the option that says Improve Inking and Typing, which records everything you type and write on your device to supposedly improve handwriting and keyboard recognition.
Disable Activity History
Windows has a feature called Activity History that tracks everything you do on your computer including which apps you open, which files you access, and which websites you visit, and it can sync all of this information to your Microsoft account stored on their servers. To disable this, go to Settings, then Privacy and Security, and click on Activity History. Turn off the toggle that says Store My Activity History on This Device and also make sure the option to send activity history to Microsoft is turned off. You can also click the Clear History button on the same page to delete everything that has already been recorded about your past activity.
Turn Off Location Tracking
Windows tracks your physical location and shares it with apps and Microsoft services by default. To stop this, open Settings and go to Privacy and Security, then click on Location. Turn off the main Location toggle at the top to disable location tracking for the entire system. You can also scroll down and individually manage which apps are allowed to access your location in case you want to keep it enabled for specific apps like maps while blocking it for everything else.
Disable Advertising ID
Windows assigns every user a unique advertising ID that tracks your interests and browsing behavior across apps and websites to serve you targeted advertisements. Disabling this does not stop ads from appearing but it does stop Windows from building a personal profile about your interests and sharing it with advertisers. To turn this off, go to Settings, then Privacy and Security, and click on General. Turn off the first toggle that says Let Apps Show Me Personalized Ads by Using My Advertising ID and also disable the other options on this page including the one that tracks app launches to improve your Start menu and search results.
Disable Cortana and Search Data Collection
Cortana is Microsoft's virtual assistant and it collects a significant amount of data including your voice recordings, search history, calendar information, and personal preferences to function properly. If you do not use Cortana regularly, it is best to disable it entirely. To do this, click on the Search bar in the taskbar, go to Search Settings, and turn off Search Highlights and Cloud Content Search. You can also go to Settings, then Privacy and Security, and click on Speech to turn off online speech recognition, which stops Windows from sending your voice data to Microsoft's servers for processing.
Disable Background App Permissions
Many apps installed on Windows continue running in the background even when you are not actively using them, and during this time they can collect data, access your camera or microphone, and communicate with external servers. To control this, go to Settings, then Privacy and Security, and scroll through the list of permissions including Camera, Microphone, Contacts, Calendar, and others. For each one, you can see which apps have access and individually revoke permission for any app that does not genuinely need it.
Turn Off Timeline and Tailored Experiences
Windows also has a feature called Tailored Experiences which uses your diagnostic data to show you personalized tips, advertisements, and recommendations inside Windows itself. To disable this, go to Settings, then Privacy and Security, and click on Diagnostics and Feedback. Scroll down and turn off the toggle labeled Tailored Experiences. While you are there also turn off the Feedback Frequency setting by changing it to Never, which stops Windows from periodically asking you to send feedback about your experience.
Use a Local Account Instead of Microsoft Account
One of the most effective steps you can take to reduce data collection is switching from a Microsoft account login to a local account. When you sign in with a Microsoft account, a large amount of your activity, settings, and preferences are automatically synced and stored on Microsoft's cloud servers. Switching to a local account keeps everything stored only on your own device. To do this, go to Settings, then Accounts, click on Your Info, and select the option to Sign In with a Local Account Instead. Follow the prompts to create a local username and password and your account will no longer sync data to Microsoft's servers.
Use a Private Browser and DNS
Even after adjusting all Windows privacy settings, your browsing activity can still be tracked through your browser and your DNS provider. Switching to a privacy focused browser like Firefox or Brave significantly reduces online tracking, and changing your DNS server to Cloudflare's 1.1.1.1 as covered in a previous article prevents your internet provider from logging every website you visit.
Keep Windows Updated Despite Privacy Concerns
Some people consider disabling Windows updates as a way to prevent data collection, but this is strongly not recommended. Windows updates contain critical security patches that protect your computer from hackers and malware, and disabling them leaves your system dangerously exposed. The better approach is to apply all the privacy settings described above while still keeping your system fully updated, giving you both security and privacy at the same time.
Taking back control of your privacy on Windows does not require any special technical skills or expensive software. By going through these settings carefully and making the right adjustments, you can dramatically reduce the amount of personal data Windows collects about you and enjoy a much more private and secure computing experience every single day.
