I'm running Windows 10 Pro on an SSD. Whenever I turn on my computer, File Explorer opens up. It's a nuisance and I'd rather not have it open at every startup. I've checked article upon article and everything seems normal. My registry keys for Userinit are normal, Shell is normal, and restore folders upon startup is not on. It's almost like Explorer is being told to open twice, but I can't find where the problem is. The Startup folder doesn't contain explorer.exe either.
The programs I have running in the Startup folder: Killer Network Manager; and the programs I have running on boot are: Delayed launcher (Intel), IAStorIcon (Intel Rapid Storage Technology), Java Update Scheduler, NVIDIA Backend, NVIDIA Capture Server Proxy, System Control Manager (SCM), and Xear Audio Center.
Any ideas? If anybody needs more info about my PC, ask in a comment. I do have a secondary drive (an HDD.)
