Windows 11 system tray & audio broken — DISM RestoreHealth fails (0x800f0915) even with local ISO source; in-place repair install also failed

Hi, I've been dealing with this for over 24 hours and could use some help.

System: HP Laptop 14s-dq2xxx, Windows 11 Home Single Language, Build 10.0.26200.8973, x64, Intel i5

Issue: System tray (network/volume/battery icons) is missing from the taskbar, and audio has stopped working entirely. Windows also falsely shows "no internet" despite a working connection, and Windows Update says "Repair Version of Windows not found."

What I've tried:

  • DISM /ScanHealth confirms real corruption ("component store is repairable")
  • DISM /RestoreHealth fails with 0x800f0915, both online and using a local Windows 11 25H2 x64 ISO with /Source /LimitAccess
  • CBS.log shows the real cause: CBS_E_REPAIR_CONTENT_MISSING — it's looking for old package versions (10.0.26100.1591 / 1742) that aren't in any current ISO
  • Full in-place repair install via Setup.exe reached "Installing Windows 11" but failed after restart with "Windows 11 installation has failed" (temp logs were auto-deleted before I could check the exact reason)
  • System Restore is unavailable — no restore points exist

Is a clean install my only remaining option, or is there something else worth trying first? Has anyone hit this same combination (corruption confirmed, but repair blocked by missing legacy package versions, and even in-place repair fails)?

Thanks for any help.

Hi,

I should have provided more details; the "clean install" I mentioned refers to the USB flash drive method. I had understood that you had tried the ISO or Windows Refresh method and they hadn't worked.

You are absolutely right—just make sure to note down your activation key and back up your data before proceeding with the clean install.

If you'd like, I can guide you on how to create a USB flash drive with the Windows installation files, if necessary.

Thanks.

    Hi Ivan,

    Thanks for the reply. A bit more context that should help skip a few steps:

    I've already tested this across accounts — I checked another Administrator profile on the same machine, and the taskbar/system tray/audio problems occur there too. So this isn't a single corrupted user profile; it's system-wide. I also confirmed my account is genuinely in the Administrators group (net localgroup administrators shows it), and I can get a real High-integrity elevated token via Task Manager → Run new task with admin privileges — whoami /all confirms BUILTIN\Administrators is enabled, not deny-only. So this isn't a standard permissions issue either; msconfig's error message appears to be a misleading symptom of deeper corruption rather than an actual privilege problem.

    Where I'm actually stuck: I already agree a clean install is likely necessary — component-store corruption is confirmed via DISM /ScanHealth, and CBS.log shows CBS_E_REPAIR_CONTENT_MISSING (it's asking for old package versions like 10.0.26100.1591/1742 that aren't in any current ISO, online or local).

    The problem is that even a clean install attempted from within the existing Windows installation fails. I tried:

    1. In-place repair via Setup.exe (Keep personal files) — reached "Installing Windows 11," failed after restart, logs were auto-deleted before I could check.
    2. Full clean install (Keep nothing) via Setup.exe from inside Windows — got to ~21%, failed again. This time I captured the logs, and they show repeated 0x80070005 (Access Denied) during device inventory/compatibility scans, with a fatal error: failed to mount C:\$WINDOWS.~BT\Sources\SafeOS\winre.wim.

    So there appear to be two separate issues: the component-store corruption itself, and a second problem where Windows Setup can't complete even a clean install when launched from inside this installation.

    System Restore isn't an option either — System Protection was disabled and there are no restore points.

    Given the SafeOS WIM mount failure, my plan is to boot directly from a USB installer (bypassing the existing Windows environment entirely, rather than running Setup.exe from within it) since that avoids whatever is blocking Setup from inside the current install. Does that sound right to you, or is there something about the 0x80070005 you'd want me to check first before going the USB-boot route?

    Thanks again for the help.

    Hi,

    Try the following: access local administrator mode and see if the problem persists.

    Open the command prompt (adm) and run the command: 'net user administrator /active:yes'. If successful, restart and access the Administrator account.

    There will be no password.

    If the problem does not occur, please inform us here; it is likely that your Windows account profile is corrupted.

    If so, your Windows is very corrupted, and a clean install is the best option.

    Before performing a clean install, back up your files and use ShowKeyPlus to note your activation key as a precaution.
