Of late, My laptop has been extremely slow. I tried debugging the reason. Using this, How can I identify the culprit of my slow Windows shutdown?. I did found that idle process is taking 70% of the CPU Time
The screenshots are as follows:

First: what is your taskmanager say is taking all those CPU-cycles? Second: Try disabling your virusscanner (mcshield.exe) to test if it's that one. – Rik – 2013-09-30T09:29:38.173
The idle process isn't taking any of your time. Your computer is probably waiting on something. Like, "stop Service X" but Service X needs to phone home to say "I'm stopping" before it stops and "home" is some dodgy server that's not always responding or fast.

– ta.speot.is – 2013-09-30T09:32:23.470Can you provide a spec of the system, how old is the system, and is it always slow or only slow at times? As it stands, this question is very broad. – Dave – 2013-09-30T09:32:50.140
It is a thinkpad and it is pretty new (1 month old). It runs core i5-3320M, 8GB RAM and 256GB SSD. It is not always slow but at times yes, extremely slow. I'm just wondering where to start debugging. Taskmanager seems to be pretty clean. – psteelk – 2013-09-30T10:52:05.120
Have you tried disabling your virusscanner (mcshield.exe) to test if it's that one? – Rik – 2013-09-30T10:54:12.210
Yes, I did. Just that I'm not able to replicate the scenario. Will update once I'm able to do it. – psteelk – 2013-09-30T11:46:32.957
what is slow? When it the laptop slow? – magicandre1981 – 2013-09-30T17:28:57.030
Using taskmgr, display the processes. Click on View > Select Columns and display the CPU column. Click on the CPU column to sort by usage. What processes show as consuming a lot of CPU? Also, is it only shutdown that is slow? – Debra – 2013-10-01T05:11:27.417
