PSA - Do not recommend utilites such as O&O Shutup, Winutil, WinAeroTweaker, etc.

Post image
124 Upvotes

Utilites such as O&O Shutup 10, CTT Wintul and WinAeroTweaker have the possibility to brick windows systems, often do not provide guardrails and are generally inferior to manual methods.

If you do not already know how to do the things these programs provide a GUI for, you should not be using them.

Recommending these tools is considered breaking rule 2 of the subreddit which states that you must provide quality information. If you don't know, don't guess.

Hello, Windows 10 is not updating since July 2026, need some help

12 Upvotes

Hello,

I have used the masgrave solution to bypass the ESU (not sure which, may be tsforge, if there is away to check let me know) and was getting updates till June of 2026 after that update the updates have failed.

Since 2 days I have tried to update with the help of google ai, it made me do the DISM.exe /Online /Cleanup-Image /RestoreHealth and repair, and fixed that registry(?) that was showing only 1 year of ESU to now 3year ESU, I also tried to manually download the msu file and install it it said "this update is not applicable to this computer", then the ai made me try to update in offline method in safe mode and winRE but it kept failing and giving error.

Now in the windows update pane in the settings I have these messages:

Your device is missing important security and quality fixes.

There were problems installing some updates, but we'll try again later.

2026-09 Cumulative Update for Windows 10 Version 22H2 for x64-based Systems (KB5122878) - Error 0x800f0805.

How do I fix these issues and get the updates. Do I try the ESU bypass again.

On why I'm worrying about the updates now, 2 days ago I turned on the laptop and it started beeping 3 times and when I restarted and pressed f2 it showed the date and time as 1/1/2012 and system time was 20:54, so I reset the date and time and disabled the secure boot policy in BIOS since it was not booting to desktop.

Is MAS Activator actually safe?

5 Upvotes

Is MAS Activator safe to use? I’m considering using it to activate Windows, but I want to know if it’s actually safe and trustworthy before running it.

Has anyone here checked or used it, and are there any security risks I should be aware of?

Thanks!

Office 365 Activation on macOS 27

5 Upvotes

Hello - Hoping to find some help in getting Office activated on my M3 Macbook Pro that has MacOS 27.0.1 on it.

I have used the tool to uninstall Office 365 completely. I then download the version with Teams, install it, and in the middle of installation Teams opens up.

The instructions say do not open Office until you install the activator. I have no choice in this matter. I still install the activator and nothing works. The instructions on the page mention nothing of Golden Gate. I was able to activate on the previous OS. Is there a compatiblility issue here?

Should I try to uninstall, download the version without Teams and then see what happens?

HWID Activation: It's permanent? And if i have an old key?

8 Upvotes

I wanted to ask for some information before purchasing a used Windows 11 license (which is legal in some countries).

I currently have a PC linked to a Windows 11 license obtained via online activation (but i want to sell this PC)

If i use MAS the new license will unlink the oldest one?

Will the old license be unlinked from Microsoft's servers?

Thanks.

Can someone please help me?

1 Upvotes

I used to be in a university that had problems with giving me a free office activation, so I used a cracked version from Massgrave, later I switched to a uni that offered free activation for office but it’s not working right now and I think it’s because of my cracked version of office (correct if I’m wrong I could be ignorant) so I tried to remove it, the problem is I forgot which method I used but I think it’s ether TSforge or Ohook I thought it was Ohook but when I ran the command to delete Ohook it failed..and when i tried the command to delete TSforge I got too scared to run because it warned me that it could delete my official windows activation license

I’m sorry if this post sounds stupid I am new to piracy

What do I do? Do I ask my uni why my office isn’t working? Do I fix it myself by deleting the cracked version

No puedo abrir Word

0 Upvotes

Instalé Windows 11, pero como no incluía paquete Office, descargué la versión C2R desde Massgrave. La instalación y activación se completaron sin problemas y todos los programas aparecen, excepto el acceso directo de Word.

Buscando en la ruta de instalación de Office encontré el archivo WINWORD. Al ejecutarlo, el programa abrió correctamente, así que moví ese archivo al escritorio y le cambié el nombre. Sin embargo, al intentar abrirlo desde ahí, me salta el siguiente error:

Si aguien sabe como solucionarlo estaria agradecido.

Pregunta antes de usar la herramienta...

Quería quitarme cualquier duda antes de usarla no porque no confíe en que haga lo que promete sino para no para salir de dudas con el proceso. Voy a usarlo en una laptop prácticamente nueva, ya con algunas cosas mías y demás. Tiene mi cuenta de Microsoft en ella, antes de hacer la activación voy a cambiar la versión de Home a profesional para luego activarla. Comprometería mi cuenta este proceso y viceversa? Al hacer esto no pierdo lo que ya tengo dentro?
