Fix Microsoft Compatibility Telemetry High CPU Usage Error

Microsoft Compatibility Telemetry is a service present in Windows 10. Its main job is to collect and send usage and performance data from your computer to Microsoft.

While many suspect that Microsoft spies on people, Microsoft claims that the constant monitoring of our computer and data is to improve system security, fix bugs and enhance our system’s performance.

But, the main problem apart from collecting data is that these data occupy huge spaces on our computer. The high disk usage or high CPU usage error that we constantly face is due to this accumulation of data in our system.
