April 19: Official Dell Support Statement Regarding the Bug

...The root cause has been identified as an issue being caused due to “Windows 10 display Cache issue”...

Here's a video example if I didn't explain it well enough: File Explorer - Streamable

I understand that, it's not a big deal but it doesn't do it with the nVidia card disabled.

If I open File Explorer from the taskbar, I get about a 0.5-1 second delay from clicking it.

If I use the Windows + E key, it is instant.

The lag seems to be only when starting it but this...

I just received a new MSI GL62M 7REX-1067 laptop, I did a clean install of Windows 10 when I got it. Everything is fully updated and works very well.
However, I have this lag when opening...

Have you looked at the power options, such as advanced, it could be using less power for the CPU, etc

Yeah, I did have to download one of the drivers from Dell, the Windows one worked but it was missing a feature for something, can't remember now. But the old driver worked fine.

Surprisingly Windows had all of the drivers.

My dad's Dell Inspiron 6400 laptop that I fixed up for him.

Runs pretty decent for casual surfing, nothing special.

Windows 10 Enterprise N 2016 LTSB x86
15.4" Widescreen Display
Intel Core...

Run Services.msc, Go to Windows Update, Double click, stop the service, set it to disabled, then apply.

Have you tried to reinstall any of the browsers, also try resetting Internet Options to default in Control Panel and clearing Internet Data.

You can stop updates with any version by disabling the Windows Update service.

Didn't notice that last part. Ok, let me see your task manager processes and background processes.

Try running a malware scan with Malwarebytes or similar.

I switched back to 2015 LTSB because the 2016 one (anniversary version) used more of my CPU for some reason.

I wonder how effective tools like SpyBot beacon are. I have used it to patch the leaks for spying and have done various other edits, such as removed Cortana, etc.

When I check my ports and use...

While that is true, he still has the right to privacy. To answer your question, yes it's going to spy on you, just like most email and websites do.

Also even though being a new drive, it could be possible that you got a bad drive.

Which software did you install? And did you notice any problems before or after

What method are using to do a clean install

Do it within advanced startup with the command prompt if your not able to login and initiate it.

It's "Chkdsk C: /r" C would be whichever letter your drive is.

Run a chkdsk and fix errors and then do a reinstall. Hopefully your drive can be fixed. May be time to look into getting a new drive though.

Also yours may be like mine where you can use BIOS or UEFI. You have to tell the motherboard to use one or the other.

The 2nd video, is relevant to the services, which are at the end.

But again, if you prefer, the black viper list is great..
