so in the following python script, we have:

Code: 
def process_data(byte_array):
    process_is_on = False
    ch = byte_array[18]
    size = len(byte_array)

    if ch == 0x15:
        process_is_on = True
        for i in range(10, 15):
            ch = byte_array[i]
            if ch != 0xff:
                byte_array[i] += 1
                break
        byte_array[18] = 0x13
        for i in range(24, 22, -1):
            for j in range(i, size - 2):
                byte_array[j] = byte_array[j + 1]
    elif ch == 0x13:
        process_is_on = False
        for i in range(10, 15):
            ch = byte_array[i]
            if ch != 0xff:
                byte_array[i] += 1
                break
        byte_array[18] = 0x15
        n = 0
        while n < 2:
            for j in range(size - 1, 23, -1):
                byte_array[j] = byte_array[j - 1]
            n += 1
        byte_array[23] = 0x10
        byte_array[24] = 0x00
        # extend array
        ba = bytearray(1)
        ba[0] = 0x00
        byte_array.extend(ba)
        byte_array.extend(ba)
    return process_is_on


def write_data_to_registry(byte_array, process_state):
    size = len(byte_array)
    retval = False
    try:
        hKey = winreg.OpenKey(winreg.HKEY_CURRENT_USER, STATUS_PATH, 0, winreg.KEY_SET_VALUE)
        winreg.SetValueEx(hKey, STATE_VALUE_NAME, 0, winreg.REG_BINARY, byte_array[:size])
        winreg.CloseKey(hKey)
        retval = True
    except:
        pass
    return retval


The above numbers are corresponding to these REG_BINARY Keys (which obviously change ever time the toggle is flipped, but the mathematics work despite the changes as they are absolute)

Code:

SO.. given this template and seeing how it got the byte_array numbers, what are the correct numbers to plug in for the following keys?:

[Epoch filetime in UTC... 82,03,63,78,79,9c,db,01]... null separated bytes... terminated by double null's.

Rule #1 of reverse engineering:

Collect as many data samples from different PC's and users. Compare and contrast. Just because you know a set of bytes changed, doesn't mean you understand what the rest of the bytes actually do. "...,9c,db,01" is always a sequence that strongly implies its a stored UTC timestamp.

[Epoch filetime in UTC... 82,03,63,78,79,9c,db,01]... null separated bytes... terminated by double null's.

Rule #1 of reverse engineering:

Collect as many data samples from different PC's and users. Compare and contrast. Just because you know a set of bytes changed, doesn't mean you understand what the rest of the bytes actually do. "...,9c,db,01" is always a sequence that strongly implies its a stored UTC timestamp.

had a hunch you'd be the first to respond lol. so i can get data from 3 PCs in the morning to add to this. just so you know, this is in reference to the Do Not Disturb toggle in settings.

Turn it on, refresh the below reg entry. then off and refresh reg again:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount\$$windows.data.notifications.quiethourssettings\Current\Data

Those hex bytes were strangely familiar...
I stopped working on this script a year ago. Except for the "wtf does this unexplained byte sequence do?", this code kinda makes the recipe's ingredients more obvious.

Code: 
function QuietMoment {
    param (
        [ValidateSet('Presentation','Game','Fullscreen')]
        [string]$Rule,
        [ValidateSet('Priority','Alarms')]
        [string]$Focus,
        [ValidateSet('on','off')]
        [string]$Enabled
    )

    $DateValues = ([System.BitConverter]::GetBytes((Get-Date).ToFileTimeUtc()) | foreach { ('{0:x2}' -f $_).ToUpper() }) -join ','

    if ($Enabled -eq 'on' ) {
        $EnabledValues = ',01,C2,14'
    }
    else {
        $EnabledValues = ''
    }

    $UnknownByte = switch ($Rule)
    {
        game { '28' }
        default { '26' }
    }

    if ($Focus -eq 'priority' ) {
        $PriorityOnly = (('Microsoft.QuietHoursProfile.PriorityOnly' | Format-Hex).Bytes | foreach { ('{0:x},' -f $_).ToUpper() }) -join '00,'
        $FocusValues = $PriorityOnly
    }
    else {
        $AlarmsOnly = (('Microsoft.QuietHoursProfile.AlarmsOnly' | Format-Hex).Bytes | foreach { ('{0:x},' -f $_).ToUpper() }) -join '00,'
        $FocusValues = $AlarmsOnly
    }

    '[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount\$quietmoment{0}$windows.data.notifications.quietmoment\Current]' -f $Rule

    $DataValues = '02,00,00,00,{0},00,00,00,00,43,42,01,00,C2,0A{1},01,D2,1E,{2},{3}00,C2,28,01,CA,50,00,00' -f $DateValues, $EnabledValues, $UnknownByte, $FocusValues
    '"Data"=hex(3):{0},\' -f (($DataValues -split ',')[0..19] -join ',')

    $ByteCount = ($DataValues -split ',').Count

    for ($i = 20; $i -le ($ByteCount - 24); $i += 25) {
        '{0},\' -f (($DataValues -split ',')[($i)..($i + 24)] -join ',')
    }
    '{0}' -f (($DataValues -split ',')[($i)..$ByteCount] -join ',')

    ''

Sorry. Refresh the page, I had to shuffle two string constructs inside the function instead of existing outside of it. My bad.

haha way more than i was trying to do. i was literally only trying to get this toggle to trip on and off:
1742795133841.webp

the python script used in the Night Light toggle uses the same styled script (hence my snippet in the first post). once the math is figured out, it literally flips the toggle in real time (live view when .py is ran)

*finally found the original source. it was a github cli. i added the url to the nightlight thread (had a stackoverflow link where someone shared it but wasnt the original source).

not sure if you're interested in this topic or not. if not i can quit tagging you lol.

update - played with it for an hour or so today. figured out how to toggle Notifications on/off with powershell.
also how to add/remove apps from the Priority list of allowed & calls/reminders via powershell.

1742876580793.webp

what else i've found is that when the binary data changes (in my original post), it is changing the default profile, which i knew but didnt know the reg naming for it offhand:

1742876663176.webp

OFF = Microsoft.QuietHoursProfile.Unrestricted

1742877076936.webp

so instead of messing with the binary, as it will take me forever to figure that out, i'm going to shift focus to figuring out how to change the profile via Data name instead. any ideas?

When I was playing around a year ago, 23H2(?) only had two profiles:
Microsoft.QuietHoursProfile.PriorityOnly​
Microsoft.QuietHoursProfile.AlarmsOnly​

I imagine you do a switch() and pick one of the three strings to inject into the byte array.

I tried that (unless i did it incorrectly... possibility). i'll keep playing with it

also - just compared the data for the 2 on a different machine. may help me try to figure out the python attempt, but i'm just leaving these here for completion's sake

Isnt it easier to just disable toasts for "DnD" behavior?

The first block is the UTC timestamp, written in big-endian bytes. 9D,DB,01 never changes as the preface (right to left). Think of it as an anchor.

I just finished watching "The Imitation Game" last night on streaming. Break out your ASCII table...

U-n-r-e-s-t-r-i-c-t-e-d
P-r-i-o-r-i-t-y

Dude, it's a data structure flattened into a byte array. Some items are just number value bytes, some are strings. What's not obvious is how the function reads back the data stream and delimits the different struct fields. And since it's supposed to be a data struct, the size (length) of each field can widely vary so you have this shifting of relative positions. The numerical fields are probably fixed in byte length, representing a specific word size (uint, uint16, etc.)

yeah i figured out how to do that one already. just a 2 line ps script. i want to figure the dnd out just because.

time for me to do some more homework. there is a method to the madness and it will be found! if not for any other reason than to control what Microsoft doesnt want us to control :lmao:

also - check the breakdown the OG for the nightlight posted on his git. great insight, and i cant imagine the toggle for
Code: 
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount\$$windows.data.notifications.quiethourssettings\Current
would be TOO different (obv the factors invovled with light effect, etc - but similar layout)

It's really simple. When someone asks "What's the time?" You reply "well it's 35,82,76,c9,4a,9d,db,01".

progress! little google (brave), tons of stackoverflow & reddit and lack of sleep lmao. got the python to TURN OFF Do Not Disturb when it is on. works live, no reboot or explorer restarts necessary (it restarts the WpnUserService to force the change). i CANNOT for the life of me get it to toggle DND ON when it is off...
