How to set Windows 11 to hibernate automatically (hibernate after) hibernation

Just to be clear, Windows has two low-power modes:

Sleep - All non-essential activities and drivers are stopped and the processor goes into power-conservation mode

Hibernate - The current system state is stored to hard drive, and the system powers off

Sleep is enabled OOTB and can be controlled by control panel.

You can enable hibernate from the advanced power settings in control panel.

In Windows 10, you can set the timeout so that after sleeping for a certain duration, the PC automatically hibernates to go to deep power saving.

Windows 11 seems to be missing the UI feature to set that time out and by default it's set to a very long time (like 16 hours)

Here's how to enable hibernate and set the timeouts by the command line.

如果要从UI上enable：Control Panel | Power | 选择电源按钮的功能 | 休眠显示在电源菜单

Open an elevated command prompt (run as administrator)

Enable hibernate:  powercfg /HIBERNATE ON

Query the current hibernate idle settings: powercfg /Q

Look for a section that looks like:

Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e  (Balanced)

  GUID Alias: SCHEME_BALANCED 

  Subgroup GUID: 238c9fa8-0aad-41ed-83f4-97be242c8f20  (Sleep) 

    GUID Alias: SUB_SLEEP 

    Power Setting GUID: 9d7815a6-7ee4-497e-8888-515a05f02364  (Hibernate after) 

      GUID Alias: HIBERNATEIDLE 

      Minimum Possible Setting: 0x00000000 

      Maximum Possible Setting: 0xffffffff 

      Possible Settings increment: 0x00000001 

      Possible Settings units: Seconds 

    Current AC Power Setting Index: 0x00000000 

    Current DC Power Setting Index: 0x00000e10

0x00000e10 = 3600 seconds

To set the DC power (battery power) timeout: powercfg /x  hibernate-timeout-dc 60

This will set it to 60 min or 3600 seconds or 0x00000e10 seconds

You can even make it work when on AC power (plugged in): powercfg /x  hibernate-timeout-ac 60 

Windows Virtual Desktop / Session / Workspace

 This program was made for people who are using Windows 10's built-in Virtual Desktops, but who don't like the default key-binding, don't like how you can't cycle through your desktops (If you are on your last one you don't want to hotkey over to the first one 8 times), and don't like not knowing what desktop # they are on.

Firefox monospace font is not used

Today I found that my Firefox 57 doesn't render the monospace font correctly anymore. It should render Consolas font, but for some reason it renders as Serif font.

After a little debugging, I found that this was caused by the Windows 10 language & region formats. I set it to Chinese (Simplied, China).

How to fix:
Instead of modifying the Latin font settings in Firefox, change the Chinese, Simplied font settings to Consolas instead. My problem was fixed by that.
