Windows 10: File Explorer slow and Start menu icons not highlighting after update

Hi, I wasn't planning on doing anything with it, I just wondered what it was and why it was using so much CPU. The name is a bit vague, could be anything!

Thanks

 

Yes, a simple name. Been called "System" since XP days, or before.

 

zinou - been a few hours since I restarted, and so far everything is working great. Looks like you might have hit the nail on the head.

Thanks again. I'll see how it goes over the next few days *Smile

 

There some applications that uses shadow copy, like backup applications, Hyper-v ...

To delete orphaned Volume Shadow Copies, you can use this command "vssadmin delete shadows /all".

 

Hi zinou,

I can't run that command as I disabled VSS! I'd need to re-enable it, run the command and then disable it again.

However, looks like if I disable VSS, then restore points won't be created. Is that right? How about windows backup, does that require VSS? Don't want to lose either of those.

You say that VSS is used by Hyper-V. I only started seeing these problems after I installed Hyper-V. I wonder if VSS on its own wasn't the problem, it was Hyper-V's usage of it that caused the problem. If so, enabling VSS without re-installing Hyper-V might be OK.

Any thoughts? Thanks again

 

Hi
Enable vss then run the command to remove orphane Volumes. It may solve your problem . Then let the service startup type manual and see if the problem will occur.

 

Thanks, I've done that. Let's see what happens now *Smile

Thanks again for all the help.

 

Hi Youssu,

Keep us informed...

 

Sad to say, it's doing it again. My machine was just locked up for about 5-10 minutes. All 8 cores were showing at 98% activity, nothing worked. I tried starting the performance recorder, but couldn't get anything to respond. Windows Explorer died, the taskbar went black, nothing was responsive. I could see the system process in Task Manager at the top of the list in the Details tab. I have them sorted by CPU usage, the window was still visible when the activity happened, and the odd times it refreshed, this process was at the top.

It's come back to life now, but no doubt it will do it again.

I can't work like this. It's killing my machine. I can't say I'm keen on disabling the service, as system restore and backup seem to depend on it, and it seems that there's something fundamentally wrong if such a basic part of the OS is crippling my machine. Surely there must be a better answer.

Any ideas? Thanks again.

 

Hi Youssou
i can't answer right now. I'm a bit sick. I have an idea to identify which program is creating this shadow copies by using process monitor.
Talk soon.

 

Thanks for letting me know. I hope you feel better soon (for you as much as for me!)

 

Have you tried to backup With file history, when VSS.exe service is disabled. I'm not sure that File history rely on VSS to do the backup job !

 

Hi zinou, hope you're feeling better.

As I said in my reply of the 4th Dec, I have the VSS service running, it was just killing my machine.

However, someone (elsewhere) suggested running Windows install (I used the Media Creation Tool, as I didn't have my installation disk handy), and that seems to have done the trick. I'm not holding my breath, but all seems back to normal now.

Thanks again for all the help. Unless the symptoms start again, I guess we'll have to write this off to one of those Windows things!

 

Do you mean you have done a fresh Installation of Windows 10 ?

 

I'm having the same issues where file explorer and other programs are taking a long time to load. Restarting would fix it but then it would get slower over time. Hope to hear back for any updates!
