I worked on some Windows app that registers a Windows service with a C++ code like this:

SC_HANDLE hService = ::CreateService(
    hSCM, m_szServiceName, _T(SERVICE_NAME),
    SERVICE_ALL_ACCESS, SERVICE_WIN32_OWN_PROCESS,
    SERVICE_AUTO_START, SERVICE_ERROR_NORMAL,
    szFilePath, NULL, NULL, _T("RPCSS\0"), user_name, password);

where user_name and password are strings that are provided by the app user during the app install. Assuming the service name is MyService this creates a registry key HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\_SC_MyService that is hidden by default and even administrator does not have a permission to read it and regedit does not show the content of HKEY_LOCAL_MACHINE\SECURITY key by default. But fortunately the access can be allowed by right clicking on HKEY_LOCAL_MACHINE\SECURITY and selecting Permissions or alternatively by running

Enable-TSDuplicateToken

in PowerShell. To list the content of the key I used the following command:

dir HKLM:\SECURITY\Policy\Secrets\_SC_MyService

My Windows 10 PC started to glitch a little bit and I scanned its disks with the following commands:

chkdsk C: /f /r /x

The type of the file system is NTFS.
Cannot lock current drive.

Chkdsk cannot run because the volume is in use by another
process.  Would you like to schedule this volume to be
checked the next time the system restarts? (Y/N) y

This volume will be checked the next time the system restarts.
