Windows 10 randomly goes blank and lock screen displays on wakeup

So this is a strange one.  You set all the power settings correctly and yet every now and again the system goes into suspend mode.  This can be terribly annoying because you have to put in your credentials to unlock the screen after coming out of suspend.  And worse yet, this can happen in as short of a time as two minutes!  Yes, 2 minutes.

Turns out the standard time out when a computer is left unattended with no user logged in is two minutes.  But, here’s the rub, you can’t change that by default!  Now you may ask why in the world would that setting even come in to play if the user is still logged in?  That’s a good question and likely a bug (or feature if you are a Softy).  In any case one fix for this annoying situation is to uncover the unattended timeout setting via a registry setting change.

Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0
Double click on Attributes
Enter number 2.

Now go back to advanced power settings in the power control panel/power plan.  You should see the “system unattended sleep timeout” setting which will be set to 2.  change it to something longer or zero which will disable unattended sleep.

This bug/feature is present in windows 10 up through 1803 at least.

More on this.  Why does this appear to be random?  Well, it’s not really random.  There is another hidden setting that has an affect on this.  Its called “Allow sleep with remote opens”  and by default it is set to On under battery power and OFF when under AC power.  So what is a remote open?  Terminal emulation?  Nope.   Outlook Email?  Nope.  Web browsing?  Nope.  A document that is saved on a server?  YES.   So the user may not realize what they have open when the mysterious sleepy time hits.  And good luck in getting an accurate answer when you ask them about what they do or don’t have open.

Windows 10 and when shutdown isn’t really shutting down.

Windows 10 is soooo stable it doesn’t ever really need to be shutdown.  Or that appears to be the belief at Redmond these days.  Well we all know that is a big pile of manure.  In their infinite wisdom MS has set the default action of shutdown in windows 10 to turn the machine off, but not really.  The machine goes off but it saves the state  of memory so that when you turn it back on, it just picks up where it left off.  Pretty much like the old Hibernate behavior from the Windows 7 and earlier days.  But here’s the thing, they don’t tell you that’s what is happening or any obvious way of changing the behavior.  In fact the only way you find out that windows never really shuts down is that when you look in the system log, you never see an event log event stating that it was started, which means it never shut down.  Turns out this is a behavior caused by a power setting in Windows 10.  Find the Settings page for Default power buttons. (It’s under the “Chose what the power button does” heading on the left side in the power options section of control panel - at least until they move it again)  On that page the first shutdown setting item is “Turn on fast startup (recommended)” .  By default that is checked.  Uncheck that setting and from now on, when you tell your system to shutdown, not only will it power off, but when you start up, windows will actually start from scratch instead of the state it was in when you shutdown.  Off is now really off.
