Windows 10 introduced a feature called 'Fast Startup' which allows the computer to start faster and Windows recommends to have it enabled however there are problems occurring due to the 'Fast Startup' feature.
Among the problems Windows 10 'Fast Startup' brings is the incorrect loading of device drivers. Windows 10 'Fast Startup' does NOT load drivers properly and that is a fact.
So, if you are using Windows 10 and your network keeps dropping or your printer does not work or your video cameras and virtual video cameras don't work with applications like Skype for example then you should disable Windows 10 'Fast Startup' and everything will go back to working properly again.
I believe Microsoft's idea is valid but the technology is not ready yet so I recommend to turn it off on your Windows 10.
Note also that important Windows 10 updates re-enable 'Fast Startup', so make sure to check your 'Fast Startup' settings after a Windows 10 update.
You can use the following steps to enable or disable fast startup.
1. Type Control Panel in the search box.
2. Click Control Panel.
3. Click Power Options.
4. Click Choose what the power buttons do.
5. Click Change settings that are currently unavailable.
6. Scroll down to Shutdown settings and uncheck Turn on fast startup. Click Save changes.
