File Explorer slow and Start menu icons not highlighting after update

Since the big update on Sunday (for me anyway), whenever I use File Explorer, it takes ages to do anything. I can double-click a folder, and it will take about 5 seconds to open it. Even when it opens it, I often get "Working on it" for a few seconds before the files show.

As often as not, when I double-click, nothing happens at all. Sometimes it opens the textbox to rename the folder (despite me double-clicking), sometimes it just doesn't do anything.

This happens on both of my disks, one of which is an SSD, so it's not like the device itself is going slowly.

Also, when I open the Start menu and hover my mouse over an icon, the icon is not highlighted. Sometimes it highlights the icon above or below, sometimes not.

As you can imagine, this is making working with the machine very difficult.

Anyone any ideas?

P.S. The more I use this machine, the more everything seems to be dragging. I just tried opening Task Manager, and it took about 2-3 minutes before the window was ready. I could see it painting the various bits of the window as it went along.

What you can do to troubleshoot that the right way and get answers to your problem is;

- Download and Install windows Performance Toolkit Windows ADK downloads - Windows Hardware Dev Center . Choose the package corresponding to your Windows version.

- When the problem occur, start recording a trace using Windows Performance Recorder using these options: - justpaste.it

- While recording the trace, try to work on your system for about 2 minutes. Then click the save button and give your file a name.

- Compress the resulting file

- Share it through Free file transfer, send large files - TransferNow or any other file sharing platform.

I'll analyze your trace file and give you a feedback.

See you

Thanks to both of you for the replies. I was actually just about to report back that I found out what the problem was.

Last Sunday afternoon I installed Hyper-V, and immediately started with the CPU issues. As Windows was driving me mad about the update, I assumed it was related to that, especially as the problems persisted after restarting. It never occurred to me that just installing Hyper-V would affect the system - at least not until I created a VM.

When the light bulb eventually went on, I uninstalled Hyper-V, restarted, and everything works fine.

So, nothing to do with the update at all, everything to do with Hyper-V, which has been removed from my PC, never to return!

However, zinou's tips about analysing performance are well worth noting in case I have an issue in the future.

Dalchine, I should have added some vital statistics. Will remember that for the future.

Thanks again

Are Volume Shadow Copy Enabled in the services ? If yes disable it and give it a try.

Hello,

No it's not running. It's startup type is manual, and right now it's not running.

The odd thing about those graphs is that, as I said earlier, during the last 30-60 seconds of the trace, I was only using File Explorer and nothing else, but it was grinding along really slowly. The graphs don't seem to show much during that time. I can see lots of things happening earlier, which was also slowing the machine down, but I'm puzzled why they don't show anything for that last bit.

Thanks for your help. Any other ideas?

Just noticed that the high CPU periods are often associated with a System entry in the Task Manager...



When I took that screenshot, it wasn't using much CPU, but it does sometimes. Any idea what this is and why it would use so much CPU?

Thanks again
