PC goes up to 100% disk usage at startup?

some processes randomly do this and some even do it with the cpu, some examples are:

-Windows Driver Foundation

-Microsoft Compatibility Telemeter

-and more

just end the process and everything is fine

I have done that way before, I only have a few things on startup. Not even Discord is a startup app.

try going trough the disk cleanup app thingy, helps get some storage back and removes garbage from old windows versions

Famous Windows design flaw. Your disk runs at 100% because there's startup services and user programs doing a lot of disk read work for whatever reason. It's really not that complicated.

 

Task manager is your best friend here, unless you know how to use other resource monitors. Identify what programs are the culprit and deal with them individually. If it's a user program (Say, some garbage keyboard software) - see if you can disable its "start on login" functionality. If it's a Windows component - see if you can disable it as a service.

 

If you can't deal with it in a traditional way - look for alternatives. There's scripts and methods to get rid of useless Windows bloat on bulk that you might want to follow if you've got a slow hard drive that causes the high disk usage to be an issue.

 

Refer to the below:

An advanced tool to create debloated Windows images, essentially allowing you to form an ISO without a lot of unnecessary Windows components, often being used to create "Windows Lite" images. Look up video guides on this tool, there are plenty.
