Re: PSA: Somehow, without action from me, hyberfile.sys got turned on

To continue to add value to this thread topic for everyone, one option for
those who turn hibernation off is to check the status when the disk usage
suddenly balloons.

1. CHECK SUPPORTED POWER STATES:
   C:\> powercfg /a
   (Identifies if "Fast Startup" or "Hibernation" is currently active.)

2. CHECK ACTUAL FILE SIZE ON DISK:
   C:\> dir /as C:\hiberfil.sys
   (If this file is close to your total RAM size, it is in "Full" mode. 
   If it is roughly 40-50%, it is likely in "Reduced" mode.)

3. OPTION A: THE COMPROMISE (Keep Fast Startup, but shrink the file)
   C:\> powercfg /h /type reduced
   (This limits the file to only what is needed for booting, 
   stripping out the bulky "user session" data.)

4. OPTION B: THE NUCLEAR OPTION (Kill it and reclaim all space)
   C:\> powercfg /h off
   (Note: This also disables "Fast Startup" in Windows 10/11.)

5. VERIFY THE DELETION:
   C:\> dir /as C:\hiberfil.sys
   (You should see "File Not Found." If it's still there, a 
   system process or "Maintenance Task" is likely locking it.)
