    Not bad at all.

    I have it on this system and three others as my alternate, bought versions. Also use Malwarebytes as alternate and Bitdefender.

    OK, back at home, did complete scan with superantispyware, it found a couple of things it wanted to delete, restarted, still have 149 threads and 50% cpu load. with no apps running. Now that I have superantispyware, should I turn off windows defender? Should I turn off search indexer? This machine is just used for google, email, and avr c compiler. I'd like to see it settle down to 1% like the win7 system at work.

    Defender is a quality product.

    I'm still weighing in as to what is best. I would not have more that one AV running real time protection.

    Search indexer should calm down.

    I think I would run chkdsk against your c: drive and then I would do an inplace repair. Think you said you were on 1803 so this should be a repair if you get Media creation tool today. Check name on file. Not sure when they will release 1809. I always recommend a data backup.

    There is perhaps a clue here - or it may be, in fact, a different problem:

    - these processes are suspended.

    There are references to this, but a quick search didn't find anything very helpful.

    Have you tried to disable Cortana?

    Thanx for the tips so far. I see 2 of a lot of things like cortana. Assumed it was because there were 2 cpus. Does an i5 have 4 cortanas running? Is there ANY win10 user out there that sees cpu use actually get real small? Like if you leave it running a couple of days? The win7 at work settles down to 0%. I assume thats user mode. The task switcher is still checking all those processes every quantum. How much system time is being used at 0% user time? 100 tasks uses 1ms checking to see whats ready?

    Hi cpu use solved

    bobgardner said:
    Task manager shows 50% cpu, and process monitor shows a bunch of log files being written like ntfs log, no reads. Sounds nutty. If its an optimization, it should read too, right? (haha) Win10 1803, core2duo, 8gigs of ram.
    I downloaded process explorer, evidently the predecessor to task manager's resource monitor. Same system process PID 4 was using 50% cpu, but when you click properties, it shows all the tasks and one of them was using it all. It was named stdriverx64.sys, part of an audio streaming app I had been trying out. After uninstalling the app and leaving a reason msg in the box provided in the uninstall dialog, system is using 1% cpu. Working as designed. Hope someone else can solve their hi cpu use prob using process explorer. Is this a great forum or what?

    Thanks for posting. Could you say what the name of the software is?
