Hi Alvaro Bueno Palomo,
Thank you for reaching out to Microsoft Q&A forum and taking the time to explain what you’ve been experiencing. I know how stressful it can be when a long‑standing issue affects everyday Windows features like Settings, Bluetooth, and recovery options.
The error you’re seeing (SystemSettingsAdminFlows.exe – 0xc0000017) points to a Windows system startup issue rather than anything harmful or caused by malware. Since the issue is affecting the Settings app directly, we’ll need to step outside of Windows briefly and use Windows Recovery to fix it.
Please follow the steps below:
Step 1: Start Windows in Recovery Mode
- Select Start, then choose Power.
- Press and hold the Shift key on your keyboard.
- While holding Shift, select Restart.
- Release the Shift key when the screen displays “Please wait”.
This will open the Windows Recovery Environment (WinRE).
Step 2: Remove problematic memory configuration entries
- In Windows Recovery, select Troubleshoot.
- Select Advanced options.
- Select Command Prompt.
- When the Command Prompt opens, enter the following commands one at a time, pressing Enter after each:
bcdedit /enum badmemorylist
bcdedit /deletevalue current badmemorylist
This step clears invalid memory configuration entries that can prevent Windows system components from starting correctly.
Step 3: Repair Windows system files (offline)
While still in Command Prompt, run the following command:
sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows
Allow the scan to complete. Once finished, run:
dism /image:C:\ /cleanup-image /restorehealth
These repairs restore corrupted Windows system files and services, including those related to the Settings application and Bluetooth functionality. No personal files or installed applications are removed.
Step 4: Restart and verify
- Type exit and press Enter.
- Restart the computer normally.
- After startup, verify whether:
- The Settings application opens correctly
- Bluetooth devices can be connected
- Recovery or Reset options are accessible
If the problem remains after completing these steps, I recommend performing an in‑place Windows 11 repair install. This process reinstalls Windows system files while preserving all personal data, installed applications, and user accounts. It is a standard method used to resolve persistent system corruption when other repairs have been unsuccessful.
*Disclaimer: Let’s try performing an in-place install or in-place upgrade which will refresh your Windows files and operating system without removing files or applications. That being said, we always recommend that if you have important data, you should back it up before making large system changes. If you want to back up your data first, please do so. Once you are done backing up, you can follow the steps in the following guides: How to run In-place upgrade in Windows 11 - Microsoft Q&A
If you need further assistance with any of the steps above, please let me know and I will be happy to assist.
