Thanks to an update of Windows 10 'Fast Startup' is turned on again. And I have problems with turning it off, as the 'Turn on fast start-up (recommend)' setting is selected AND greyed out 1). That selection box should be accessible when you change your 'User Account Control Settings' 2). That is a setting that is NOT changed. However, it is on the suggested setting that should make it possible for me to turn off fast start-up. But that is still greyed out. A Catch 22 situation. Does anyone have a suggestion?
