Avoid Reboot and DDInstall Reboot flags does not work .

Question

I was trying to make my device driver updates have consistent behavior when it comes to the restart of the Host PC. Tried either avoiding reboot using the COPYFLG_IN_USE_RENAMEc, but it works and sometimes does not.

Tried another approach with flag DDINstall reboot flag, and the inconsistent behavior is observed here too.

And Last tried with SERVICE_BOOT_START also still same inconsistencies with reboots.

Can you please share if something is missed in configuration or what is correct way to achieve it

Hello there,

If the files in the driver package are not run from the Driver Store, assign a new file name to each new version of a class installer or co-installer, or a service DLL. This avoids the need for a system restart if an older version is in use. (In fact, if a new file name is not used for an updated class installer or class co-installer, these new files will not be used for the installation.)

To avoid system restarts during device installations, use the following rules from the article.
