How To Fix: Windows Telemetry Service is Making My Computer Slow

Reader Question:
“Hi Wally, I was looking at startup services and I noticed that Windows Telemetry service was taking some bandwidth. I looked deeper and realized that it was uploading data by default. Can you help explain what it is and how to disable it. Thank you.” – Shawn L., Australia

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: The Windows Telemetry service can be found running in Windows 7, Windows 8, and Windows 10. It may continue in future versions of Windows as well. It is intended to improve the user’s interaction and overall experience by uploading data to windows servers automatically. You can opt out of this service simply by disabling it from within Windows.

Is Your PC Healthy?

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.

Happy Computing! :)
