Service Host: Superfetch-A pox on Windows 10 users

Windows 10 Service Host: Superfetch brings the PC to a crawl for many minutes after booting.

I rarely use my Windows 10 PC (laptop) after buying a Samsung Chromebook Plus earlier this year (see MobileViews Podcast 199: Samsung Chromebook Plus discussion w/guest Paul Lawler). Generally speaking, I boot it up once a week to post-process audio files for the MobileViews and/or ComicsViews podcast (which are recorded on a Mac). Recently, the laptop is abysmally slow and nearly unusable for 10 to 20 minutes after booting (really resuming from hibernation).

I took a look at what was going on and saw that “Service Host: Superfetch” appeared to be the culprit.

Windows 10 Services utility

This item in the Microsoft Community forum explained that Superfetch preloads applications based on usage patterns to speed up launching: What is superfetch? Its in my Window sTask Manager and it uses up a lot of CPU power …do i need it and what is it? Since my PC was essentially unusable for many minutes after booting, this seemed like a useless service to me. So, I stopped the service and disabled it using the Windows 10 Services app.

Windows 10 disk I/O returned to normal after stopping Superfetch.

End result: The PC became responsive and usable again after disabling Superfetch. Am I recommending that other people take these steps? NO. This happened to be a useful workaround in this instance. Your mileage may vary.
