This from another forum fixed this issue for me.

Got to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0\DefaultPowerSchemeValues


Edit each of the sub-keys. Each corresponds to one of the power plans. If you choose ACSettings (Decimal value is 3600 seconds for 1 hour) you are choosing a behavior for when the machine is plugged in, DCSettings are for battery power.

Mfaklis: but my system had no problem sleeping with an opened window (Outlook) prior to make the registry changes Tommy1997 suggested. And even now it has no problem sleeping with Outlook open when I manually initiate sleep.
With the changes to the registry, the system doesn't seem to honor the settings in my Power plans (Balance, Power saver, High performance nor Stable Mode), which have different times than what I entered via the registry ? Interestingly it does honor the Power settings (or did prior to making the registry changes) when I only used my laptops monitor, but ignored them and went to sleep in 2 minutes when I only use my external monitor.

You can correct this issue in the Screen Saver options. windows 10 lockscreen - Microsoft Community

Andy,

Sincerely thank you for your post on this. I was literally losing my ****ing mind lol. Your directions were spot on and were simple to follow. I created this account just to say thank you, cheers bro.

1. Click on the windows icon
2. Type regedit
3. Right-click on regedit icon, click Run as administrator
4. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0
5. Double click on Attributes
6. Enter number 2.
7. Go to Advanced power settings (click on Windows button, write power options, click on Power Options, in the selected plan click on the Change plan settings, click on the Change advanced power settings).
8. Click on the Change settings that are currently unavailable
9. Click Sleep, then System unattended sleep timeout, then change these settings from 2 Minutes to 20 for example.

Only been using Windows 10 for a week & yes, this little bug was starting to annoy me... The fix 'post above' worked for me perfectly for around 2 minutes! Turns out in the end to be VERY simple...
My screen saver was set to blank @ 2 minutes. Clicked/ selected screensaver to (none), Done, problem solved! Thanks all for taking the trouble to share!

Hi everybody with a blank screen problem my problem was of the past when i just changed my screensaver to none and rebooted

The most simplest way..

Right-click on desktop > Personalize > Lock Screen and turn this off: "Show lock screen background picture on the sign-in screen" 👍🏼

Just to be sure, enter below on Cortana lock screen settings and make sure the Lock Screen option is switched also off!!

Don't mention it, I switched to macOS for good! 😂👍🏼

Hi forum! Thanks for the above Andy and Blessa,

For me, none of this is working.

Windows 10 64-bit. The system still sleeps the screens after 3-5 minutes of inactivity, no matter what the power plan is. Even set to 45 minutes screen power-down and the screens power down betweeen 3-5 minutes!

The computer locks after about 1-2 minutes of inactivity and the screens power down at 3 minutes.

Here is my configuration:

2x nVidia gfx cards running on SLI
3x screens plugged in to gfx board #2 and none plugged in to gfx board #1.
Power and sleep:
High performance profile
When plugged in: Screens turn off after 20 min. Sleep: Never.

Here is a screen of my Regedit HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\
Notice how I do not have the following key: "238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0"

Thank you.

Thank you.

you probably have solved your issue but just in case...your screen capture showed the regkey but you had to go further into the directory by choosing to expand on the left side to get to the final 7bc4a2f9-... directory. thats where you will see the Attributes value that you can change.

i actually didnt have to do this because i just changed my theme back to the default one, and it stopped sleeping after 2 minutes ... this started after i messed with the themes and turned on screen saver after 10 minutes.
