There's been a lot of commotion over W10's privacy terms. I'm sure these methods can change/improve at any time, but here's a guide which should hopefully give you a relatively more private, safe experience, however at the risk of not being able to enjoy some of W10's features.
Do not use Express Settings. Hit Customize, and make sure everything is turned off.It's strongly preferred that you use a local account with Windows 10.
Head to Settings > Privacy, and disable everything, unless there are some things you really need.While within the Privacy page, go to Feedback, select Never in the first box, and Basic in the second box.Head to Settings > Update and Security > Advanced Options > Choose how updates are delivered, and turn the first switch off.Disable Cortana by clicking the Search bar/icon.(Optional) Disable web search in Search by going to Settings, and turning off Search online and include web results.Change the name of your PC by going to Start (or hitting the Windows key), typing About PC, and clicking Rename PC.
Open up the Command Prompt by launching cmd as an administrator, and enter the following:
sc delete DiagTrack
sc delete dmwappushservice
echo "" > C:\ProgramData\Microsoft\Diagnosis\ETLLogs\AutoLogger\AutoLogger-Diagtrack-Listener.etl
Open up the Group Policy Editor by launching gpedit.msc as an administrator. Go through Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds. Double click Telemetry, hit Disabled, then apply. NOTE: This only truly works in the Enterprise edition, but the final step provides a decent enough workaround for Pro users. While still in the Group Policy Editor, go through Computer Configuration > Administrative Templates > Windows Components > OneDrive, double click Prevent the usage of OneDrive for file storage, hit Enabled, then apply. While still in the Group Policy Editor, go through Computer Configuration > Administrative Templates > Windows Components > Windows Defender, double click Turn Off Windows Defender, hit Enabled, then apply. Open up the Registry Editor by launching regedit as an administrator. Go through HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\DataCollection, select AllowTelemetry, change its value to 0, then apply. First, download the Take Ownership tweak and enable it. Then, head to the Hosts File by going through C:\Windows\System32\Drivers\Etc, take ownership of the hosts file, and add all of the IPs from this page into the file.
