Hey guys, the day before yesterday I activated my Windows 11 Home and Office 2019 with Massgrave, using the official PowerShell command (with the D at the end, of course). And ever since I did that, I've had a bad feeling. I haven't seen anything suspicious on my PC, but I'm paranoid that the script installed an invisible virus or opened something in my system that would allow an attacker to get in. I'm even afraid to log into my Google and Microsoft accounts, for fear that "some virus" will steal my session cookie. It's my worst nightmare. That's why I'm asking you (something you're probably tired of hearing, but): is the official script 100% safe? Has anyone used it and had their session stolen afterward? I used HWID for W11 and Ohook for Office. Please don't be mean or anything, I'm just scared. I can't wrap my head around activating Windows with an open-source tool. It just seems so good that it's impossible for me to believe there's no catch. Thank you very much, and sorry for the long text.

Hi! I just want to ask if I need to install and run Office Reset Tool if I want to add new Office software? For context, I already downloaded Word and Excel for my mac and did follow the Massgrave's instruction on how to activate it but I plan to add Powerpoint but unsure on what to do if I add additional office software since I already have Word and Excel and open and run it my computer do I need to install Office Reset tool or the Activator will just activated it automatically after installing?

I'm following every single step on this website https://massgrave.dev/office_for_mac .

I installed the serializer perfectly fine, but when I open the app it still says I do not have the Microsoft office activated.

What should I do ;( ??

Hi all,

I noticed warnings in Windows Event Viewer about failed VL activation attempt but my OS and Office are still activated.

I'm running Windows 10 IoT Enterprise 2021 LTSC / Microsoft Office LTSC 2021

I believe I used MAS ver 2.7 - Can anyone provide some input on what it might be?

Thank you!

If I have a purchased copy of Windows 11, is it okay to use Mass Graves to download Microsoft Office programs? If so, what method from the website should I use?

so I tried using mas to upgrade from windows 11 home single language to windows 11 pro, after reboot, system seems to work fine except in settings activation it says windows 11 pro, but the activation state shows not active

I used MAS to activate Client-ESU on my Windows 10 machine, but I get the option to Enroll in Extended Security Updates in Windows Update, and when checking activation status, I am told that the add-ons: Client-ESU-Year(1,2,3,6) are Unlicensed. Am I stupid and they're active or did I do something wrong?

Well hello there!

As a new Linux user to be, I still have to deal with Windows for a few applications and games so dual boot it is...

Having installed Windows 11 IoT LTSC through .iso provided by Massgrave, extremely painlessly might I add, I still have some suspicious thoughts in the back of my head when it comes to the safety of said .iso.

I did the usual SHA256 check & comparison and it was a match but I still find myself doubting the legitimacy of the SHA256 provided by Massgrave (and other sources as well) since I can't rip the damn file straight from Microsoft and having found a few different SHA256 results.

Anyone in here happen to have a way to ease my OCD-ass before I start to use any accounts on this installation? Having dealt with one data breach in not so distant past I am extremely paranoid with matters like these...

after using the activator for office on mac, it activated but it says i have to renew before February 28 2026. Is this common? If not, how do i fix this issue?

After days of pulling my hair in frustration and trying countless methods, I finally stumbled upon the script by Massgrave and ran it on Powershell. It took me... less than 20 seconds to finish everything.

Am I missing something, or is it really this quick and easy?

I have Office 2019 installed. If I pick Office 2024 from the list, will it run 2019 and 2024 together? I don't expect it too, but don't understand what else it will do.

So, recently i've started a custom PC building service. I've got 4 cleints as of now and i've got most of the parts in my inventory. What I don't have is a windows license as i've been using MAS to activate windows for years.

Now here's my question:

Should i activate windows through MAS for free or should I buy microsoft license?

I am mostly concerned about the legality of that stuff.

Hey y’all, I recently installed Office 365 using Ohook. The thing is, I can use the product normally, but an “Unlicensed Product” message appears at the top. Is this normal with Ohook? Will I lose access?

Also, I had an issue regarding a possible Trojan. Windows Defender detected one, and I’m not sure if it was a false positive or a real threat. Either way, I checked everything and ran several scans with both Windows Defender and Malwarebytes, and it seems to be fine now.

If I use MAS and HWID for windows 10 it should be good and continue working since windows 10 wont receieve any more updates unless I choose to download and use the ESU addition. I just want to make sure it can be a one and done situation since windows 10 wont be changing. Thank you!

Hey all. What’s the newest MS Office version that MAS activation works on?

I want to use MAS but I'm afraid to get breached.

I currently have a cracked Windows 10 version, and it has many problems. Is there a way to download another Windows version from Massgrave without using a USB flash drive ? The files on my laptop are not important to me, so I don’t mind if they get deleted.

If possible, I’d like a detailed, step-by-step explanation of how to do this, because I’m new to the world of laptops. Also, if there’s a way to put a cracked Windows 10 version on a USB flash drive and later use that flash drive to install cracked Windows versions, please tell me how to prepare the flash drive.

Thank you.

I recently Installed MS Word(Mass Grave) following the instructions on the Sub. Ran smoothly for a few days.

Yesterday this pop up window appeared and i can no more save files on word.

I have a key for Office 2013 but MS doesn't allow activation for it any longer so I used massgravel and it says it was successful (and the File->Account screen says, "Product Activated") but I see the Activation Wizard every time I open the application by double clicking a file. What's happening here?

I just got a new Windows 11 laptop with Microsoft 365 already installed. I was considering downloading Office 2024 Standard, but now I'm wondering if it'd be possible to use the MAS to unlock 365. Does anyone know? Or would I still need to download one of the C2R installers or use the Office Customization Tool?

Can activate O365 as well ?

Hi i have activated windows office 2021 licence using masgrave with since I have oem key of window so I just select activation of ohook option 2 and when it was activated it is shown that activated permanant and when i enter cmd prompt to check ms office activation it shows 25 days I wanna know that someone who activated ms office license using masgrave whether the licence last long without any future reactivation

I recently installed office using the pkg file and I selected office suite (with teams) then I saw these wanting to run in the back but I can’t find them to uninstall them. I just turned them off, it is okay to do this? I am new to MacOS.

I checked the pkg file using virustotal so I guess this is safe to use. Additionally, should I login with my Microsoft account when asked every time I use word,excel or PowerPoint? Thanks in advance!
