5562	Windows installation is slow because of anti-malware checks?	Francesco Casella	Adeel Asghar	"I have uninstalled and reinstalled OMC for Windows a zillion times in the last few years. After I switched to a laptop with a SSD, the time for uninstallation was cut drastically, to about one minute, because the bottleneck there was the physical HDD. Conversely, installing the software still takes about 20 minutes, which is quite a pain if you do it almost daily.

By looking at the process monitor, it seems that the bottleneck is {{{Antimalware Service Executable}}}, which runs around 12% - this is one full core on my 8-core i7-8550. The installation program hovers between 4 and 10%, which means, it is not running as fast as one core would allow. Transfer to disk is a few MB/s at most, and is never reported to be more than a few percent of maximum.

Is there any way to avoid the Windows anti-malware protection to scan each and every file that gets installed, so that installation goes as fast as possible? Is this perhaps related to #4829? If so, it may be a good reason to get a certificate to skip some of the safety checks during installation."	defect	closed	high	2.0.0	Installation program		wontfix
