The scheduled tasks in the SideShow folderWhen a user logs on to a user account, the scheduled tasks in the SideShow folder determine whether a Windows SideShow-enabled device is connected to the computer. If a Windows SideShow-enabled device is not connected to the computer, the scheduled task immediately exits. If a Windows SideShow-enabled device is connected to the computer, these tasks perform the specified functions to make sure that the Windows SideShow-enabled device works correctly.
The CrawlStartPages scheduled taskThe CrawlStartPages task is part of Windows Search. The CrawlStartPages task determines whether any locations that are not notification based must be indexed. For example, the CrawlStartPages task runs if you add a universal serial bus (USB) flash drive to the index by using the Indexing Options item in Control Panel. The task runs when you add the USB flash drive if the USB flash drive uses the FAT file system, a FAT partition, or a CD-ROM location. If you have not added a location in the Indexing Options item, this task will start and then be completed immediately.
Note On hard disk drives that use the NTFS file system, Windows Search uses Update Sequence Number (USN) journaling and notification to determine when files are added, deleted, or edited. However, on hard disk drives that use the FAT file system or on other locations that are not notification based, the file timestamps must be verified against the index to determine whether the file must be indexed again.
The UPnPHostConfig scheduled taskThe UPnPHostConfig task changes the startup type for the UPnP Host service. This task changes the startup type for the UPnP Host service from "manual" to "automatic" when the service is needed.
