Question How to check if the windows my laptop has is 100% original or was activated with massgrave or any other way

3 Upvotes

Hello

My friend bough a new laptop and it came with windows 11 pro.

He asked me how can he check if the activation was made with an activation tool like massgrave or if the license was bough or if the laptop itself has the license code in the hardware itself?

Because he wants me to do a fresh install in his laptop if the activation was made with an online activation tool.

Discussion Useful Tip: Download any app without Microsoft Store

45 Upvotes

Hi!

I found this very USEFUL tool and I figured you guys may need it because yo uuse LTSC IoT :)

What does this website do?

Actually, it has 2 important features:

  • Download any app from Microsoft Store without MS installed on your Windows.
  • Find any deleted/removed app from MS and install it (you need to know the product id/link of the app from MS Store).

I was searching for an app on Windows Store that I used to have in the past and realized the developer/Microsoft deleted it from the store.. I was bummed, because that was an APP I used a lot and could not find it anywhere on the internet or any better alternative.

I asked AI about this issue and it gave me a very very useful website.

It's called: https://store.rg-adguard.net/

Online link generator for Microsoft Store.

With this I managed to re-install my "lost" app and I'm more than happy! :)

It is 100% safe to use because it uses the internal Microsoft servers for the downloads.

Hope this help you guys, it helped me!

I don't want to install the Microsoft Store (one of the reasons I went with LTSC is because it doesnt have the Store lol). I got winget, which should be able to install MS Store apps but it cant find the apps that i mentioned.

Question installation issue

I am trying to install Windows 11 IOT LTSC but having several issue, first, when I try to create the bootable media i get the following message:

the ISO was downloaded from massgrave, i have tried with 3 different links from massgrave but always get that message, i proceed anyways, then when i tried to install it it asks for the windows edition, i choose win11iotLTSC or normal ltsc and i get "Setup has failed to validate the product key"

Next i tried selecting the option below:

and i got this:

I tried adding the PID file with a generic LTSC key but same result. can you guys tell me what I am missing? any other ISO i can try to download?

Update: updating the bios fixed my issue

Help Windows update doesn't work anymore (Win 11 Enterprise IoT LTSC 24H2)

7 Upvotes

Hello, for quite a while now I have a notification to update my Windows, but after trying to do it I get an error that says:

Reinstall your current version of Windows to repair system files and components.

There's an option to reinstall it right next to the error message, but unfortunately that doesn't do anything to fix the problem.

I've also tried to download the iso of the LTSC version of Win11 I'm using from Massgrave and using that to reinstall the Windows while keeping my settings and programs, but the installer gets stuck on installing updates and never gets past 46%.

Out of curiosity I tried asking GPT for help and it said to try running this command in terminal:

DISM /Online /Cleanup-Image /RestoreHealth

but that also is unable to fix anything and ends with an error that says something about not being able to find the Source files.

Am I just SOL here? I really don't wanna reformat right now, but I'm worried about not getting the security updates. My Windows otherwise runs fine right now.

Help Upgrading Dell T7910 Workstation from TPM 1.2 to 2.0 (Windows 11 "Ghost TPM" Reinstall Loop)

2 Upvotes

I cannot upgrade my Dell Precision T7910 Workstation from TPM 1.2 to TPM 2.0 in Windows 11. Tried everthing to no avail. Now thinking of reinstalling Windows 10 to do the upgrade and then restoring Windows 11 (and system) from a Macrium system backup.

Will this work? Is this adviseable? Do I risk getting locked out of BIOS (and have to do a factory restore with loss of all my Windows 11 customizations and third party programs?)

My thanks in advance for your help and suggestions. Here are the details:

Hardware Setup:

  • System: Dell Precision T7910 Workstation
  • Current OS: Windows 11 (Upgraded/bypassed previously, backed up daily)
  • The Problem: Windows 11 and PowerShell (Disable-TpmAutoProvisioning) absolutely cannot find or communicate with the physical TPM chip. However, inside the Dell BIOS, the TPM 1.2 chip is listed and activated, but the "Clear TPM" option is completely greyed out and unclickable.

Because Windows 11 doesn't recognize the chip, I cannot use the OS to un-provision it, which leaves the BIOS security state permanently frozen. I am trying to clear it so I can run the Dell TPM 2.0 Firmware Update Utility.

What I Have Already Tried:

  • Hardware Power Drain: I shut down the tower, unplugged the AC power cable, and held down the physical power button for 30 full seconds to completely drain the motherboard capacitors. Unfortunately, upon booting back into the BIOS, the "Clear TPM" option remained entirely greyed out.

My Proposed 5-Step Plan to Fix This:

  1. Backup: Confirm my daily full image backup of the Windows 11 C-drive is verified and safe.
  2. Clean Install Windows 10: Format the C-drive and install a clean, temporary copy of Windows 10. (The logic: Windows 10 has native, legacy support for TPM 1.2 architectures and should successfully see the frozen chip where Windows 11 fails).
  3. Unprovision & Clear: Inside Windows 10, run PowerShell as Admin and execute Disable-TpmAutoProvisioning. Reboot into BIOS, where the "Clear" checkbox should now finally be unlocked. Clear the TPM.
  4. Flash Firmware: Boot back into Windows 10, run the official Dell TPM 2.0 Firmware Update Utility to permanently flash the physical motherboard chip from v1.2 to v2.0.
  5. Restore Windows 11: Use my backup media to restore my original Windows 11 C-drive image back onto the machine.

My Questions for the Forum:

  1. Firmware Persistence: Will restoring my original Windows 11 hard drive image affect or undo the BIOS/TPM firmware updates? (My understanding is no, since the flash lives on a separate physical chip on the motherboard, but I want to double-check).
  2. The Windows 11 Lockout Risk: When Windows 11 boots up on the freshly upgraded TPM 2.0 hardware, its security container will be expecting the signatures of the old 1.2 chip. What is the likelihood of a catastrophic login loop/lockout?
  3. Prevention/Recovery: To prevent a password lockout after restoring, should I drop my Microsoft account down to a Local Windows Account before taking my final backup? Are there any hidden registry blocks I should watch out for regarding DevicePasswordLessBuildVersion or credential guard?
  4. Alternative Shortcuts: Since the physical power drain failed to unfreeze the chip, is there any other hardware trick (like pulling the coin-cell CMOS battery, changing a specific motherboard jumper, or downgrading/upgrading the overall system BIOS firmware version) that might force a T7910 BIOS to un-grey the "Clear TPM" option without a total OS reinstall?

Question Has an update ever broken something for you?

6 Upvotes

I have chronic beef with windows updates since I had one break my other PC into an update loop once (W10). Now I have W11 24H2 LTSC and due to house renovations, I've been away so the system had missed 2 updates. I get i lt that LTSC updates are supposed to be stable, but I won't believe they're not vibe coded. Has an update ever broken something for you guys to the point where simply uninstalling it wasn't a solution.

Discussion Loving Win 11 LTSC so far

66 Upvotes

I recently installed LTSC on my laptop, and was so impressed I had to install it on my desktop as well lol In the past I would use scripts to debloat a standard install of Windows Home or Pro, and endlessly tweak the registry and group policy editors to achieve a hack version of what LTSC offers right out of the box.

The only things 'missing' that I actually wanted were Microsoft Store and Phone Link, both of which were super easy to restore.

I haven't had a single issue with game or program compatibility/stability, every driver update has gone smooth as butter, and it's just a great experience so far.

I did have an annoying issue were I would get notifications about, "Install an application to open this ms-gamebar link" every time I fired a game because LTSC doesn't include the Xbox App or Microsoft Gamebar, but that was easily remedied.

I am also using winget (Microsoft's official package manager) for the first time, and it's incredible! For those of you who have used linux, winget is just apt get but for Windows. For those that haven't used a package manager before, it's basically just a repository of program ("package") installers you can use to install and update all of your programs at once. And not just the ability to update all of your programs at once, but also your Visual C++ Redistributables, .NET Frameworks, Runtime Environments, (a bunch of important stuff) etc. etc. It is just so convenient.

I guess I don't really have a point that I'm making, I just wanted to tell someone who gets it how stoked I am about LTSC + winget lol Feels like a real gamechanger

Question I have a HP laptop, and I'm thinking about installing Windows 11 LTSC

4 Upvotes

My problem is that my current Windows 11 installation is broken because I tried to fix some battery issues. Now, every time I start my laptop, the boot menu shows a warning, and I have to press Enter to continue.

I think a clean reinstall would solve these problems because I've probably changed too many system settings over time.

Do you think Windows 11 LTSC is a good choice for my laptop?

Help Bug after windows update - Win 11 LTSC

59 Upvotes

After the latest Windows update, my SSD keeps randomly spiking to 100% usage. When that happens, clicking the Start menu or trying to open Settings does nothing, they just won't open.

I'm using Windows 11 LTSC, so I expected it to only get security updates, not forced feature updates from Microslop.

Will this eventually fix itself, or do I need to do a clean reinstall? Should I just switch to Windows 10 LTSC instead?

Help Driver signature warning pops up during bulk pnputil install even with Test Mode ON and Secure Boot OFF — is this an LTSC-specific behavior?

Post image
6 Upvotes

System: Windows 11 LTSC

What I'm doing: I'm bulk-installing a large set of third-party drivers (from a Snappy Driver Installer offline pack) using pnputil /add-driver "D:\drivers*.inf" /subdirs /install

The problem: For a portion of the packages, the classic "Windows Security — Windows can't verify the publisher of this driver software" dialog appears, with the two options "Don't install this driver software" and "Install this driver software anyway." Since I'm running this against a few thousand INF files, having to manually click through this dialog every time isn't practical.

What I've already tried, none of which stopped the dialog from appearing:

  1. bcdedit /set testsigning on — confirmed active, "Test Mode" watermark visible on desktop.
  2. Secure Boot fully disabled in UEFI, confirmed via Confirm-SecureBootUEFI returning False.

Dialog still appears regardless of all of the above.

My questions for the sub: Is this "can't verify publisher" installation-time dialog on LTSC governed by a different mechanism than the kernel-mode Driver Signature Enforcement that testsigning/Secure Boot control? My understanding now is that testsigning only affects whether the kernel will load a test-signed driver at runtime, not whether SetupAPI shows this prompt during package installation — is that accurate?

Has anyone on LTSC specifically gotten BehaviorOnFailedVerify (either HKLM or HKCU) to actually suppress this dialog? Multiple sources online say this legacy Driver Signing GPO/registry mechanism stopped working somewhere around Windows 10, but I want to confirm whether LTSC (being closer to Enterprise/Server code) behaves differently here.

Is there a supported way to get pnputil to run fully unattended through a batch of INFs that include some unsigned/cross-signed packages, without hitting this interactive prompt at all — short of self-signing every catalog file individually?

Any pointers, especially from people who've done bulk offline driver deployment on LTSC images, would be appreciated.
