System Volume at the toppest level at startup

My home pc running win7 is having a strange issue since last two days... Just after the moment i log in, system start up sound is heard at the top volume. When i click the volume icon at the notification area the slider is found at the top level. Even though i mute my volume level and shut off again at startup it is found automatically at the top level. How to troubleshoot this annoying problem ?

check your startup programs or something you installed in last 2 days.something is taking control of windows audio at startup.

I checked up the task manager for running programs at startup and found one program called 'pmbvolumewatcher' and suspecting that by its name i disabled it.....but after restarting the system the same problem is there... i'm posting my startup program list & see if u could trace out something

try this.disable task scheduler service in services list & then restart pc.after restarting if problem remains check by opening task manager & see if taskeng.exe process is present(like in your 2nd pic).

I'm unable to disable task scheduler. Its not active for disabling

post a screenshot of task manager service in services list.

plz go through the screen shots

last one goes here

not that one.i meant the service named "task scheduler"(in your 15.jpg pic).

Just check tasks scheduled in start up. Even CCleaner shows it, from where you can delete them.

i don't have cc cleaner.... any other option

did you read my earlier post & tried my suggestion?

IMO, run a full anti-virus checkup.

thats what i told... there is no provision for me to disable the task scheduler

I'm using microsoft security essentials and it says system is ok

If you can't disable task scheduler, then you can disable the tasks itself. And how much effort does it takes to instal ccleaner ?

Exactly. OP don't have any easier option than installing CCleaner.
