Laptop suddenly lagging, unresponsive

I recently had Windows 7 Ultimate x64 bit installed on my laptop and it was operating perfectly for about three weeks... That is, until a few days ago when I decided to upload some photos from my camera. It was quite a few, over 200, but I have plenty of disc space. Suddenly it has slowed down, and at times unresponsive. It will freeze up for a few minutes, then suddenly continue with whatever I was trying to do. It doesn't make sense to me that uploading photos would do this, but that's the only significant change that I made before this started.
In case it's a coincidence and it is a virus, I've run rkill, Malewarebytes, Advanced System Care, and a full Avira scan. Nothing has come up. Any other suggestions?
Thanks for your help!

How to Publish a Snapshot using Speccy

Edit: I would also like to suggest that you download and run Process Explorer.

Download Process Explorer: http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx
Unzip ProcessExplorer.zip, and double click on procexp.exe to run the program.
Click on View > Select Colunms.
In addition to already pre-selected options, make sure, the Command Line is selected, and press OK.
Go File>Save As, and save the report as Procexp.txt.
Attach the file to your next reply.

Ok, here is my Speccy publish, and my Process Explorer results are attached: http://speccy.piriform.com/results/IBQXU9gwVlaTy5lQe6ZQ88m



I deleted the photos, and have rebooted since, and it seems to be running a little bit better now (though still lagging at times).

I appreciate your help!!

Are you not using the network sharing feature in Windows Media Player?

If you are temporarily disable this service.

1. Open up Services from Control Panel, or type services.msc into the start menu search/run box.

2. Double click on Windows Media Player Network Sharing Service, and then change the service start up to Manual.

This will temporarily disabled the service unless you manually start the service. Restart the computer and check if the service has been stopped and the CPU usage had come down.

Eureka! That was it! I could tell the difference as soon as I stopped the service.
I only need that service if I want to use the fancier features of WMC, like watching videos from my computer to my TV? I don't plan on doing that any time soon.
I really appreciate your help!!! Thanks!!

Glad to be able to help.
