Samsung Galaxy Book laptops screwd over a Windows update?
Posted by Ok-Net428@reddit | sysadmin | View on Reddit | 124 comments
Yesterday a few laptops at the company I work at started showing an "C: drive not accessible. Access denied." message. Took a look and find some reports pointing at Galaxy Book Experience app. Noticed that it started after those laptops installed KB5079473 Windows security update.
After a while some drivers seem to stop working, like the trackpad, cannot even open powershell because the binary is within the C drive.
Any facing the same issue and if so, only samsung's? Found other solution rather than clean install?
Note: The laptop is within an Active Directory domain and it won't even let me modify NTFS permissions of the C drive using the administrator credentials.

Here to share my experience... Had same issue so I visited Samsung authorised store in motinagar but they just blamed Windows and said they have no information about it. Also they asked for 1000+ rs to fix it... Contacted customer care they told me to add "Everyone" with Full Control on C drive. It did solve the issue but it obv gave all the apps the permission to messup everything (as if they are not doing enough already lol). So I tried reset ("keep files" and "remove everything" both). Still "Everyone" had "Full Control" so chatgpt told me that it's not safe. So the final solution was full clean Windows install using USB. Took so long had to install drivers later. But finally the issue is solved.
I've seen ppl here fixing it using WinRE, permission edit etc etc, that do solve the issue but it's not safe if you don't know what you are doing. So if you wanna skip all that just do clean USB install and live a new life.

Has this yet been fixed? Still going through this on my book 3 360

Same thing happened to 2 Samsung laptop on my company yesterday. Fixed it logging as admin, taking ownership of The C disk and manually restoring default disk permissions using another laptop as a model.
No_Lingonberry_4313@reddit
can u walk me through a bit more in detail ?
it would be really helpful :)
Threepwood70@reddit
Sure. You need to log in in Windows with an admin user. Then right click on the C disk icon, then click on "Properties", select the Security tab and then click on the "Advanced" button. From there you must click on the "Change ownership" link and set your user as the disk owner. After you did this, you must re-add the correct groups back on the permissions list (like SYSTEM, "Users", "Authenticated users"). To know wich groups to add and The correct permissions you must to use another computer as a model. After you did this, you will click o the "Apply" button. A lot of error messages will show up, but in the it will work. The disk C will vexame accessible again.
berynoicememer@reddit
You're a lifesaver man 😭🙏🏻 It works. It wasn't letting me change ownership tho. Had to use cmd to reset ownership by icacls C:\ /reset /t /c /q Then added my normal user to the principals. Works just fine now.
No_Lingonberry_4313@reddit
thankss :)))
Retax7@reddit
It doesn't let me change ownership of drive, nor I can even open task manager even with a power user. Any other fix?
Threepwood70@reddit
You need an admin user to do it. A power user nowadays is almost the same as a standard user. Only an admin user can take ownership of a disk. You can also set a group as the owner (like "Administrators")
Retax7@reddit
I tried enabling power user via command mode, but it wouldn't let me. Anyway, found the solution by entering safe mode via command mode and disabling lua and user behaviours.
Foreign_Worry_8869@reddit
Everytime I tried to get into anything it was like windows was locking me out more. The quickest and easiest fix is to use Samsung Recovery. Turn the PC off and back on but keep pressing F4 before the Samsung logo appears.
NecessaryTradition70@reddit
Sou técnico dos notebooks da Samsung no brasil e para resolver esse problemas sem a necessidade de formatação basta:
Abrir o gerenciador de arquivos > clicar com botão direito na unidade "C\" > Propriedades > Segurança > Avançadas > Alterar > Digitar o objeto que quer selecionar que nesse caso é "Todos" > confirme > marque a opção de substituir o proprietário em subconteiners e objetos > Clique em Alterar > Escreva e selecione a opção "Todos" novamente > confirme e aplique.
Após isso apenas dê "Enter" em todas mensagens de aviso, enquanto isso o sistema fará uma varredura completa no seu disco C:\, quando finalizar reinicie apague os arquivos da lixeira caso solicite.
Asleep-Road5830@reddit
This might be related Quick share not working recently and tried everything even after reset not working do you think it's because of Bluetooth drivers not upto date or this Same as C problem?
KN1GHTM4R5@reddit
Agradeço, funcionou e consegui as permissões de volta, mas é normal que depois dessa atualização, ele estar extremamente lento, travado e usando muita memória RAM?
HevertonFreire@reddit
Aqui está exatamente assim. Páginas travam por exceder o uso de ram. Basta alternar entre 2 ou 3 abas e o notebook chora, trava, fecha tudo. Prejudicando demais meu trabalho, fui totalmente pego de surpresa. Gosto demais da Samsung e utilizo todo ecossistema, mas esse tipo de erro não devia acontecer, muito menos demorar tanto tempo pra ser resolvido.
ExpertNext2523@reddit
Eu também consegui resolver o problema dos aplicativos, mas o notebook continua extremamente lento, travando e dando erro em páginas do Google. Vocês conseguiram resolver essa parte?

Parece que é um problema geral nos Galaxy Book 4. Entrei em contato com o suporte da Samsung pelo aplicativo pré-instalado no note e o atendente disse que estão cientes já desse problema e que é para esperar uma nova atualização que será lançada corrigindo o problema (não há previsão de tempo). Ele disse para eu fazer tudo menos reinstalar o windows por pendrive (acho que perde todos os recursos da Samsung e depois é muita dor de cabeça para conseguir de novo).
ImportantInfluence29@reddit
Mas isso seria a parte boa. "Todos os recursos da Samsung" foi o que quebrou com as maquinas.
Assim que eu recuperar meu PC farei questão de desinstalar todos os softwares desta empresa irresponsável.
PersonalGuarantee122@reddit
duro é que eu tenho todo o ecossistema Galaxy, daí eu amo alguns recursos (como o app notes, usar o tablet como segunda tela, etc)

2 weeks ago my Samsung Galaxy Book 4 laptop had many problems after "KB5079473 Windows security update" such as Unable to access C drive, No fingerprint sensor detected, unable to open some of my store apps, Doesn't Boot properly and can't even shut down properly. Fortunately i backed up my files and went for a clean install and updated my windows except "KB5079473 Windows security update". I paused that update for 5 weeks. Its annoying that i need to remember myself to pause it after 5 weeks. But now my windows is working fine and fixed all my problems. I'm afraid to update "KB5079473 Windows security update". Is there any thing i could do?
No_Lingonberry_4313@reddit
I hit the same issue on my Galaxy Book - C:\ access denied right after a Windows update.
Looks like it’s tied to Samsung’s own apps, not Windows itself.
What’s worse, Samsung support quoted me Rs.1100 for a fix because it’s “out of warranty,” even though this seems to be a known issue caused by their software.
Didn’t expect to pay for something like this, which is infact like paying for their fault just to get my laptop in place ?!!

follow these! and if you already recovered c drive access you can skip to the commands.
this basically pushes you back to the previous version, so make sure to pause updates after you log back in to avoid installing the faulty update again

Hello, I got my c drive back but fingerprint, bluetooth, and microsoft services are not working. I tried fixing the drivers by uninstalling and installing, but the same error symbol appeared (yellow exclamation near the driver name). And additionally, chrome is not working properly. Has anyone experienced the same issues? If so, how do y'all fix this?
Rich_Percentage_7492@reddit
How did you get your c drive back Please explain
Thenerdy9@reddit
idk if this is why I was spared, but I had Bitlocker on. When I entered the key, it unlocked my C drive. But, I still couldn't use my PIN or biometrics to sign in -
Instead I clicked to reset my pin, completed 2FA, then clicked cancel so I didn't reset the PIN and I was in every time.
Thenerdy9@reddit
I had Bitlocker on and so I was just annoyed that I'd have to do 2FA every time I signed in to Windows Hello.
I don't really need Bitlocker, so I was gonna turn it off to see if that helped..... But did that somehow save access to my C drive?

Isso é um problema de perda de permissões.
O caminho pra resolver é esse. Vão em Alterar > Avançado > Localizar agora:
Vocês vão dar permissão de Controle Total para "Administrador" e "Sistema" dando dois cliques e dando OK
Procurem por "Usuários" e dê controle de Ler & Executar, Listar conteúdo da pasta e Leitura.
Marquem a caixa "Substituir todas as entradas de permissão de objetos filho por entradas de permissão herdáveis de desse objeto."
O Windows vai dar acesso para todas as pastas dentro do sistema.

Enable the built-in Windows Administrator account (if it isn’t already enabled):
Start Windows in Safe Mode with Command Prompt → type
net user administrator /active:yes→ restart the PC.Then log in with the Administrator account → right-click the C: drive (or wherever Windows is installed) → go to the Security tab → Advanced → change the Owner to Administrators → add Users and Administrator to the permissions for the C: drive → Apply → restart the PC.
That should fix it.
Emgguitar@reddit
Isso resolveu pra mim. Galaxy Book 4 NP750XGL-XG2BR
Porém o windows não reconhece o leitor biometrico por nada, já atualizei, reinstalei.... nada resolve
dragon3025@reddit
Thank you. This sort of fixed it for me, but there's still something wrong.
I could use everything fine, but after restarting my PC I couldn't. After some testing, I've realized that I have to sign into Administrators, sign out, then sign into my Profile (the only one on this PC) for everything to work. I don't want to have to keep doing this, and it sounds like there's something buggy still.
It seems like all fingers are pointing to Samsung right now, but I'm not using a Samsung PC. My PC, which didn't mess up until this update, is a HP Victus 15L. I also searched my apps for Samsung and found nothing.
DefinitionNatural218@reddit
I tried this, but they say that even as an administrator I can not access the drive. What should I do?
National_Baker_9506@reddit
I did this on three Samsung Galaxy Book 3 laptops and it worked. I just realized I didn't mention that when you right-click, you have to go to Properties and then follow the remaining steps. Did you do that?
DefinitionNatural218@reddit
Yeah I did. It didn't give me any permissions
Firminossauro@reddit
I had the same issue here with my personal notebook. It’s a galaxy book4, and my solution was to start with cmd and: Diskpart - List Disk - Select Disk 0 (in my case was zero) - clean disk. Only then I was able to reinstall everything. I tried a lot of things but o my this worked
Regards
Zealousideal_Eye553@reddit
Does it wipe all the data?
Firminossauro@reddit
Yeah, in this case as soon as you get into the disk park and list the disk, you’ll see that will show your disk have 0bytes available… So when you clean it it will swipe everything and you have to reinstall the OS and so on. My only recommendation is to have either a lan cable to connect in the modem, because for some unknown reason while reinstalling it wasn’t finding my WiFi network. In general it’s like you just picked up the notebook and unboxed
nkbyhisgrace@reddit
This worked and this is the only solution available that fix the problem completely. Thanks for your support and help to resolve this as many samsung galaxy book users are facing this issue.

I did that, but when the computer gets to the login screen, there's no way to switch my user to the Admin user.

Eu tive o mesmo problema e consegui resolver criando um novo usuário criado pelo administrador...
Mas eu estou tendo problemas com o leitor biométrico
O windows não reconhece por nada. O chat da Samsung disse que a engenharia já sabe desses problemas e estão fazendo uma atualização para solucionar.
Mas meu usuário eu tive que excluir

Right-click C: Drive > Properties > Security tab. Click Advanced.
2. Change the Owner Next to "Owner," click Change. In the white box, type your Windows username or email. Click Check Names (it should auto-fill the full name) and hit OK. Click Apply and OK on all windows to save.
3. Set Full Permissions Re-open Properties > Security. Click Edit. Select your username from the list. Check the box for Full Control under "Allow." Hit Apply and OK.
4. The "Error" Trick (Important!) You will likely see a bunch of "Error applying security" pop-ups. Keep clicking OK. * Windows is just skipping system files it can't change. Keep going until it finishes, and you’ll have your access back.

O erro está nas propriedades do C: logo quando vc tenta acessar aparece ACESSO NEGADO, nisso vai ter quer colocar novamente todos os usuários que estavam em Propriedade - Segurança- Configurações Avançadas, vc colocar seu login como Administrador do C, ou seja mudar o proprietário do C para seu login (Administrador) e depois vai entrar novamente nas configurações avançadas e colocar 3 usuários importantes que são Usuários autenticados (deixar todos ativos exceto controle total), SISTEMA (ativar todos COM controle total) e Administradores.
neko_smooches@reddit
My c drive access got denied. I made the mistake of asking chat gpt for solution and executed various commands in cmd. And the problem got even worse. I had no other option but to reset the system completely wiping all the files.
I don't think the problem is completely solved even after completely wiping the system. I am able to access c drive but in c drive properties along with my current username it also shows few accounts as unknown accounts. Also I am not able to create a restore point, it shows error.
Zealousideal_Eye553@reddit
i think in this case install a clean windows
Nachito206x@reddit
You should login with Administrator account, go to C drive, go to properties, Security TAB and ensure that Authenticated Users and Administrators are present in the list. If not, you should add them and give full control.
Foreign_Worry_8869@reddit
I tried all that and was continually blocked even though I am the administrator , the more solutions I tried the worse it got so in the end I used Samsung recovery using the F4 method and reset it. Now I've got a new issue and Samsung apps are not functioning properly
neko_smooches@reddit
I too have reset the my book 4. For me everything functions properly but when I tried to create a restore point it shows error.

Had this since yesterday, and I thought I had malware. Thankfully someone on cybersecurity reddit told me about this bug, since only a few hours ago I realized I couldn't access my C drive (and all my problems were likely caused by that). I’m already making a back up of important files that I can access in case I need to install a clean version of Windows 11. Tried to use safe mode to check for corrupt files but it can’t even open the cmd. I really thought I had downloaded some horrible virus or something. HOW does a Windows update even do this!!??? Today I updated It when I didn’t know this was the issue but nothing changed. Hopefully they fix it soon before I keep trying to fix stuff myself and break everything for good.

Last_Inevitable_5548@reddit
You have to factory reset it with samsung recovery. That is the only option. Keep pressing F4 key while powering on to get into samsung recovery. And then reset it from samsung recovery environment. Before that you can backup your data on D drive. Since it will only format C drive
Foreign_Worry_8869@reddit
Thats what I did but it created another issue with Samsung apps
Ok-Net428@reddit (OP)
Honest suggestion, wipe and install windows with no samsung software at all. Some solutions on the thread worked as fix, as I fully recover one of the laptops that had the issue, but I'd rather get rid of samsung apps. Windows fncks it up every now and then, If I can take anyone (Samsung) out of the disaster equation then good bye Samgung

geraldoazv@reddit
For everyone struggling with the C: drive access denied error on Samsung Galaxy Book 4 after KB5079473, I found a technical solution that might work without factory resetting. It seems to be a corruption of NTFS permissions caused by a conflict with Samsung Galaxy Connect. Since the Windows UI blocks you from changing permissions, you have to do it via a WinPE bootable drive (like Sergei Strelec). I watched this video by Juliano Lopes Info (in Portuguese, but the visual steps are clear) that shows exactly how to restore the System and Administrators groups: https://www.youtube.com/watch?v=COwDr0pYny4
Windows Defender might flag the WinPE tools as false positives during USB creation. I'm waiting for an official fix myself, but this is the most solid technical path I've seen so far.

I tried taking ownership of the C drive using the details provided here but some programs just don't work.

This afternoon, March 12th, I've already seen that it's some kind of update they released, and that an "epidemic" of this problem is coming. I feel like I'm going to be screwed tomorrow!!!

You CAN get access back to c: by taking ownership of the drive in properties security... search around the best way to do it.
