Windows 7: High CPU Use (100%), suspected to be due to dllhost.exe processes

High CPU Use (100%), suspected to be due to dllhost.exe processes

I apologize if this is in the wrong place, but it seemed the most likely place to put it.

I have a Toshiba laptop running Windows 7 that has been fairly unproblematic for most of its life. On Firday, I downloaded Audacity and MP3 Slkkype recorder. The computer functioned fine for the rest of the night, but on Saturday, it was running with a ridiculous lag. I opened the task manager to take a look, and the CPU was at 10% use. I looked in processes, and found about fifteen different dllhost.exe processes. Malwarebytes and my regular antivirus turned up no related issues.

I took a look at it with Process Monitor, and the majority of the processes either had to do with a supposedly Microsoft published software file that I couldn't find, or Internet Explorer temporary files, most notably for a site or search term that I don't think anyone has ever made use of (it read "driving sports").

When my internet went offline due to the power going off today, all of the processes dwindled until they were gone. CPU percentages remained erratic and moving around, but they rarely rose above twenty percent. When the connection came back, so did the dllhost.exe processes.

Does anyone know how I might be able to fix this?

Hello and welcome Tech mate things I would be running would be sfc and a chkdsk for starters. Some system specs would be real good too

SFC /SCANNOW Command - System File Checker

Disk Check

System Info - See Your System Specs

Personally I would run these too

Plus if you have not got it already run CCleaner CCleaner - Download
