Windows 11 100% disk usage

I don't have IDE/ATA/ATAPI controllers idk what to do I can't switch to a new one.Pls help.

This worked for my Lenovo ideapad 330.

I have also struggled with this problem for so long. Even a fresh install of windows and it still happens. I have seen this issue since 2017. Upgraded my machine in 2020 just because of this issue but it did not help. I tried everything on this thread. The post about the PCIe conflict and the registry edit seemed promising but did not work for me. One post here guided me to the dell website. I have a dell Inspiron. The dell site suggested setting the virtual memory size to double system ram. That seemed to have significantly sped up my machine though it still shows 100 percent disk usage. I have ordered an ssd (which is much more affordable these days) and more ram. Hopefully these items will make my computer useable again.

Hi, I had the same problem... I tried updating my my drivers were updated, using a drivers using an updater software program. This resolved some problems, but not all.

I then noticed that Microsoft upgraded me to windows 11 pro, however I only had a windows 10/11 home license. This inconsistency caused a license activation problem. I had to purchase a windows 11 pro license key and activate the software.

As soon as I activated the windows 11 pro software, I noticed that I haven't been getting the 100% c: drive usage any longer.

One thing to note, I bought the windows 10 home license from microsoft website to avoid activation problems like this to happen. unfortunatley that didn't work, I was miffed, and didn't want to pay full price for a windows 11 pro license, especially since Microsoft messed me up, so I went through another dealer at a fraction of the cost.

Thank you, I understand most of what you say. The latest Windows 11 Update (89G!) seems to have fixed the problem. My computer slows down when an update has been released but not installed.
