100% disk usage and slow boot

Hi, I have a Dell Inspiron laptop for about three and a half years and in recent months its boot is slow and in the first minutes, it uses 100% of the disk.
It has some heavy programs like Visual Studio, Android Studio and more on it, but it's not always been like that.

I use windows 10 home. The computer has Intel I5 CPU and 8GB RAM.

Are there suggestions for improving the computer's performance?

 

Taskhostw.exe CPU usage 100% slowing everything down

I hope someone is able to help as I have spent the entire weekend driving myself insane trying to fix this.

My laptop started running slow and freezing. I use it for writing and emails, no gaming or anything exciting.

It turns out my CPU usage is at 100% due to taskhostw.exe.

I have tried everything suggested online. The SFC scan, system restore etc. I tried seeing if I could close things in task manager but there are 90 processes running and I have no idea what is was. None seem to be using CPU according to that though. Any advice is welcome. Thanks!

 

Windows 11 bug. Process uses 100% of the CPU

Hi guys I was able to solve my issue, by going to the power option and resetting it to default.

I had also tried to lower the CPU usage option to 70% (to a lower percentage than 100).

Any of these two steps helped me solve my problem.

If the above steps do not solve your problem then do check the task manager for some random processes running in the background which causes the PC to slow down.
