disabling autorun services hence boosting performance

I am using windows 8.1 on my laptop having an i5 processor, 2GB graphics card and 8GB DDR 3 RAM.

I am experiencing slow startup and shut downs of my laptop. I want to disable certain services from autorunning. This will help me in speeding up my machine.


Using Technet's systeinternals app, I did analysis of my laptop and found the following entries. I ran sfc /scannow in both normal and safe modes and found nothing


I don't want to mess with AMD radeon and right click context menu entries. They are the services that I used regularly.

Which of the services can I safely disable without damaging my operating system?

I found no errors when I checked my drives by going to properties>tools>error checking.


I also found no errors when I ran memory diagnostic tools than run upon restarting.


Moreover, I daily run Ccleaner application to cleanup my temporary files.

The first thing I would do is enable boot logging as shown in this tutorial:

Usually if you have slow boot up you find retries in the log file. When it does not find a driver it tries again. This can often involve a 15 or 30 second time out while the system waits for the driver to load. It only takes a few to add minutes to the boot up.

As for which services settings to optimize if that becomes necessary, Black Viper's site is a good resource:
