Hello,
If it's a device driver it will more than likely use setupapi to install.
you can look in the c:\windows\inf\setupapi.dev.log for entries recorded at
or close to that time.
Some applications can use setupapi as well.
So you may want to check c:\windows\inf\setupapi.app.log for entries
recorded at or close to that time
If there was an OS update installed, most of those should be recorded in
one of the following logs
First look at c:\windows\windowsupdate.log to see if any updates were
pushed down, their install may have been pended awaiting the reboot.
More detailed and quite noisy however but most OS updates are recorded in
here.
C:\windows\logs\cbs\cbs.log
If it's not an OS update or a driver update then the OS may not log the
installation.
Thanks,
Darrell Gorter[MSFT]
