Hello, my laptop is really slow and explorer.exe is the culprit. I know it has to be from a Shell Extension that is causing this. Everytime I open a folder, explorer window or do a search this happens.

Very ridiculous. Is there a way to view which extension is doing this and disabling it?

Very frustrating!

Try Autoruns (http://technet.micro...ernals/bb963902), that lists (among many other things) which Shell Extensions are loaded.

Thanks. Can that tool show me which extension is causing the CPU spike?

Try Process Explorer http://technet.micro...s/bb896653.aspx and click on explorer, then click View/Lower pane view, then search by handles or dlls first, that will show you what is hooked/loaded in explorer. or try process hacker http://processhacker.sourceforge.net/

Hope this helps.

Make sure you download the right version, x86 or x64.

Thanks for the links. Autoruns helped me the most.

I noticed several entries for Acronis and that is not even installed anymore. I removed all entries.

i just opened My computer and have Task manager open in another monitor. It was spiking before just doing this but not now. It is not all rosie though.
 

When I do a search for *.psd files which I use a lot the search starts and I see a quick spike, then it went away but came back and now it stays high. When I close the search it goes away.

I do have an extension called Sage Thumbnails which I like because it allows me to see PSD thumbnails and not the generic PS Icon. No need to open PS to view these files.

Could it is be this extension or the search? I should also mention that I see 2 explorer.exe during this time. 1 remains low and the other is the high one
