Windows 10 slow initialization | high disk / cpu / memory utilization

I've been using Windows 10 since mid-2016 and it was working fine, until some day after a system update around dec-16 the initialization would take forever. I mean around 5 to 10 minutes to start up Windows. The system initializes with black screen and the mouse cursor active, but need to wait all the mentioned time to load the desktop and enable the system for use. I am running a core-i7 4770 with 16gb RAM and SSD, so the initialization should take a few seconds.

Apparently the issue is caused by the "Microsoft Compatibility Telemetry" app / service which takes all computer resources to do some dirt work and send data to Microsoft.

After sniffing the internet for a solution, I found the below to solve the problem:

1. Disable Feedback Frequency: Go to Settings app > Privacy > Feedback & diagnostics and under the Feedback frequency, select Never from the drop-down menu. I also set the Diagnostic and usage data option to Basic.

2. Use PowerShell (run as administrator) to stop the Diagnostics Tracking Service and change the Startup Type to disabled:

# stop-service diagtrack

# set-service diagtrack -startuptype disabled
