Disabling some of these services will make features such as Cortana not work properly or give you less than desirable results in Web Searches as just two examples.
As always, YMMV so if you do disable all the services on this list, please keep the list handy so you'll know what you've disabled should you need to re-enable a service for an application to perform acceptably.
And now, the list:
Disable Telemetry Disable Biometrics Disable Handwriting Data Sharing Disable Handwriting Error Reporting Disable Application Telemetry Disable Inventory Collector Disable Steps Recorder Disable enabling Lock Screen Camera Disable and Reset Cortana Disable Location Disable Sensors Disable Web Search Disable Windows Media DRM Internet Access Defer Windows Upgrades Disable App Notifications Disable Password Reveal Button Disable and Reset Advertising ID Disable SmartScreen Filter for URLs Disable Sending Writing Info Disable Access to Language List Disable App Access to Location Info Disable App Access to Camera Disable App Access to Microphone Disable Getting to know me Disable App Access to Account Info Disable App Access to Calendar Disable App Access to Messages Disable App Access to Radios Disable Sync With Devices Disable Windows Feedback Requestes Disable Windows Update Sharing Disable Windows Update for other Products Disable WiFi Sense Disable Windows Defender Disable Automatic Windows Updates Disable OneDrive Disable Automatic Driver Update
Note: I do *NOT* provide support for enabling/disabling the services above. If you're not familiar with enabling/disabling services or troubleshooting applications that misbehave you're on your own.
I notice in the list of things to disable:
Disable App Access to Camera
Disable App Access to Microphone
So just to be clear, it looks to me that someone accepting Windows 10 without disabling these two items gives Microsoft remote access to their computer camera and microphone so they can view you and hear you without your knowledge. Is that correct?
Any recommendations for an anti-virus anti-spyware program if Windows Defender is not acceptable?
I gotta ask. Why should “any” customer, of “any” product, have to keep a list of all things, and it seems to be an extensive list - THAT YOU HAVE TO OPT OUT OF, just to maintain your privacy?
Glad I didn’t upgrade...
