The boot time for my Desktop PC is more than 4 minutes. I would love to know what processes and services should be terminated in order to fix this issue.
I have already tried fixing up startup applications, but since, the issue is boot time, it does not help in any manner.

Processor: Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz,
