Hi, my PC has 2 drives, C: where Windows is installed ("system" drive) and D: for storage etc ("non-system" drive).

In disk management, under advanced security settings, the system drive is shown as owned by "TrustedInstaller", while the non-system drive is owned by "SYSTEM".

This is a Dell machine but I clean installed Windows when I got it. Does anyone know if the disks' ownership is correct? Should the non-system drive be owned by user(s) rather than "SYSTEM"?

Thanks :)

Looks completely normal to me. All my machines are like that too.

    fully 'Windows 11 ready' laptop. Windows 10 C: partition migrated from my old unsupported 'main machine' then upgraded to 11. A test migration ran Insider builds for 2 months. When 11 was released on 5th October 2021 it was re-imaged back to 10 and was offered the upgrade in Windows Update on 20th October. Windows Update offered the 22H2 Feature Update on 20th September 2022. It got the 23H2 Feature Update on 4th November 2023 through Windows Update, 24H2 on 3rd October 2024 through Windows Update by setting the Target Release Version for 24H2, and 25H2 on 30th September 2025 through Windows Update by setting the Target Release Version for 25H2.

    UPDATE - 11 April 2026: due to mechanical deterioration this PC has been retired from active duty. The OS with all software and files has been migrated to my System Seven in 'Other systems' to carry on as my general purpose 'main machine'.

Only if you want to apply some restrictions, I denied SYSTEM to write/modify to prevent ransomware.

My disk manager shows exactly what @Bree posted, so thankfully everything is ok, thanks :)

@TairikuOkami I'm definitely interested into that, since I'd really like windows to leave alone my non-system drive, thanks :) I still have to find complete info about it tho

Thanks to everyone for your replies :D
