Windows 10: Downloads folder extremely slow after windows update, has extremely high CPU usage

had a recent windows update, ssd btw. Downloads folder has been extremely slow upon opening and takes up a lot of CPU usage (also gets cooling fans running on high). At random intervals, the green loading bar appears to reload slowly again, although this does not seem to have any obvious impact on performance.

I have tried the recommended method of optimizing the folder for general items but it does not work (it was already the default setting for me). There are also only a few files in the folder so an overloaded folder could not be the reason as well, moreover I have had over 100 files in the folder in the past with no issues.

A quick restart used to smooth things over a lot when this issue cropped up occasionally but the problem still persists for me now even after restarting.

Another secondary issue I have is that windows is supposedly up to date, but I still get this message

You’re currently running a version of Windows that’s nearing the end of service. We recommend you update to the most recent version of Windows 10 to get the latest features and security improvements.

How can I get it back to normal?

Extremely High CPU Usage - Service Host: DNS Client

My Windows Version: Version 1909 (OS Build 18363.535)

From time to time this process (in the title) will suddenly rise CPU usage, making everything extremely slow and even games from 1994 will play slowly, for example. Sometimes it subsides by itself, but sometimes I need to restart.

I'm at my wits end - I've search everywhere and all I can find are answers for previous OS or different processes that are hogging the CPU.





How do I fix this?

Extremely high constant CPU usage


So up until this morning my Windows 10 desktop has been performing really well. When the machine is idle the CPU use is only in the 1-3% range.

For some reason my idle CPU use is now CONSTANTLY 30-40% (even after a reboot)! Task manager says its "Service Host: Local System (15)". If I expand this process in task manager it lists:





Why is this happening all of a sudden? Can anyone help please? I have all Windows Updates installed and I run an i7-3770 CPU.

My machine is now slow/sluggish with 30-40% being hogged by these services!

PS: I don't have any Malware installed as I run Malwarebytes Premium and the scan comes back clean. Some goes for a full anti virus scan.

 

Extremely High CPU Usage - Multiple system processes

My Windows Version: Version 1909 (OS Build 18363.592)

About 2 weeks ago, I opened a thread on these forums regarding High CPU Usage due to the Service Host: DNS Client system process. To summarize, I was getting up to 100% CPU Usage due to this process and couldn't figure out how to make it go away.

TairikuOkami recommended I disable DNS Client, after setting my DNS servers manually. This worked at the time and I considered the issue resolved.

However, after a week later, I still keep getting High CPU usage up to 100% due to several "Service Host" system processes. Sometimes it subsides on it's own, other times I have to play loud music to drown out the jet engine noise.





What could be wrong this time? How could I fix it?
