Hi @batrot,
Welcome to the HP Support Community.
Thank you for posting your query. I will be glad to help you.
Thanks for sharing your issue on the Pc. Persistent 100% disk usage on HP laptops running Windows 11 can be incredibly frustrating. Since you've already tried common YouTube tips, here’s a deeper, more targeted approach that often resolves this issue:
1. Disable SysMain (Superfetch)
This service often causes high disk usage.
- Press Win + R, type services.msc, press Enter.
- Find SysMain, right-click → Stop.
- Then right-click again → Properties → set Startup type to Disabled.
2. Turn Off Windows Search Indexing
- In services.msc, find Windows Search, right-click → Stop.
- Set Startup type to Disabled.
3. Check for StorAHCI Driver Bug
This is a known issue with SSDs and AHCI drivers.
- Open Device Manager → expand IDE ATA/ATAPI Controllers.
- Right-click Standard SATA AHCI Controller → Properties → Driver tab → click Driver Details.
- If you see storahci.sys, go to Details tab → select Device instance path.
- Open Registry Editor (regedit) → navigate to: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\PCI\<your device path>\Device Parameters\Interrupt Management\MessageSignaledInterruptProperties
- Set MSISupported to 0.
4. Disable Background Apps
- Go to Settings > Apps > Installed apps.
- Disable unnecessary apps from running in the background.
5. Check for Malware or HP Telemetry
- Run a full scan with Windows Defender or Malwarebytes.
- HP telemetry services like HP Touchpoint Analytics can cause spikes:
- Go to services.msc → disable HP Touchpoint Analytics Service.
6. Update Storage Drivers
- Visit Official HP® Printer Drivers and Software Download | HP® Support → enter your laptop model.
- Download and install the latest Intel Rapid Storage Technology or AMD SATA controller drivers.
I hope this helps.
Take care and have an amazing day!
