In response to a DIF code supplied by SetupDiCallClassInstaller, class installers and co-installers might perform operations that require the system to be restarted. In such situations, the installer or co-installer should do the following:
- Call SetupDiGetDeviceInstallParams to obtain the SP_DEVINSTALL_PARAMS structure.
- Set the DI_NEEDREBOOT or DI_NEEDRESTART flag in the structure's Flags member.
- Call SetupDiSetDeviceInstallParams, supplying the updated SP_DEVINSTALL_PARAMS structure, to save the revised Flags member.
After__SetupDiCallClassInstaller__returns, the device installation application that called it should callSetupDiGetDeviceInstallParams, check the flags, and request a restart if necessary.
I'd like to know when the installer or co-installer will set DI_NEEDREBOOT, thanks.

For NT-based operating systems, this flag is set if the device requires that the computer be restarted after device installation or a device state change. A class installer or co-installer can set this flag at any time during device installation, if the installer determines that a restart is necessary.
And A successful installation includes, but is not limited to, the following steps:
- Create a driver key in the registry and write appropriate entries (such as InfPath and ProviderName).
- Locate and process the INF DDInstall section for the device. The section might be OS/architecture-specific. The DDInstall section's AddReg and DelReg entries are directed at the device's software key. Locate and process the DDInstall__.HW__ section whose AddReg and DelReg entries are directed at the device's hardware key. Locate and process the INF DDInstall.LogConfigOverride section, if present, to supply an override configuration for the device. Locate and process the INF DDInstall.Services section to add services for the device (and potentially remove any old services that are no longer necessary).
- Copy the INF file to the system INF directory.
- Possibly perform the other file operations, based on flag settings in the device installation parameters.
If the DI_NOFILECOPY flag and the DI_NOVCP flag are clear, perform any file operations specified in the DDInstall section. If the DI_NOVCP flag is set, queue any file operations.
If the DI_NOFILECOPY flag is set, do not copy the files. This flag might be set if, for example, a DIF_INSTALLDEVICEFILES operation was already performed for this device installation.
- Load the drivers for the device. This includes the function driver and any upper or lower-filter drivers.
- Call the drivers' AddDevice routines.
- Start the device by sending an IRP_MN_START_DEVICE I/O request packet (IRP).
So, when some of these steps require that the computer be restarted, the installer or co-installer will set DI_NEEDREBOOT.

2023-09-14T07:27:19.8866667+00:00 A scenario is that if there are any changes that cannot take effect in running processes, it will be necessary to restart. @Ligang LG2 Guo, any update?
