Here are several ways to protect your privacy in Windows 10:

1. Update your privacy settings: Go to Settings -> Privacy to control which apps have access to your personal information and data. Review each category and adjust the settings as necessary.
2. Use a Microsoft account with two-step verification: This adds an extra layer of security to your account and helps protect your personal information.
3. Disable Cortana: Cortana is Microsoft’s virtual assistant and can collect information about your searches, interests, and location. To disable Cortana, go to Settings -> Privacy -> Speech, inking, & typing and turn off the switch for Cortana.
4. Block ads: Advertisers use cookies to track your online behavior. To block ads, you can use a browser extension like AdBlock Plus or uBlock Origin.
5. Use a virtual private network (VPN): A VPN encrypts your internet connection and helps protect your privacy when you’re online.
6. Disable location tracking: Go to Settings -> Privacy -> Location and turn off the switch for location tracking.
7. Use encryption: Encrypt your hard drive to protect your data from unauthorized access. To do this, use the built-in BitLocker encryption tool in Windows 10 Pro or Enterprise.
8. Keep your software up to date: Regular software updates often include security patches that help protect your privacy.

By taking these steps, you can help protect your personal information and keep your data secure in Windows 10.
