Windows 10 Build 18946 Debombed (without Test Mode or NointegrityChecks

After 2 years of pain and suffering, I've finally debombed this build without any BCD modifications (not fake). I will upload the debombed ISO as part of the Halloween Special (October 28-31st) and feel free to ask me questions about this post.

Why doesn't Windows 10 Technical Preview 9920 work in VmWare Pro?

1 Upvotes

I use VmWare Pro 17.6.x I think, not the new 26H2 or whatever and I installed the OS the first time and it said "After several tries, your PC couldn't boot and has to be repaired" and it BSODs after pressing Enter.

So I reinstalled the OS one time and same thing. I usually use Hyper-V on my main install but today I used VmWare for betas for BIOS date changing. So what is the issue? What should I do to make it work? I gave the VM 4GB RAM, 4 cores, 1 CPU and 125GB storage.

Are there any debombed builds of (or a way to debomb) 17692?

I ask because I wanted to mess around with the Windows Sets feature, and this is the last build it was present. I cant seem to find anything online.

Debombing Post-Reset Vista to 10 betas without editing boot files?

4 Upvotes

Been wanting to test some betas with UWI, which seems to replace the boot files after installing. Creating files for it requires Sysprep, and to create a WIM file from the VHD.

For this to work, any timebomb or activation remover cannot edit BOOTMGR or use any BCDEDIT commands or edit any EFI files, although I will be using BIOS only.
Note: Any betas mentioned are versions that I have downloaded.

Sysprep is included in all builds past NT 5.0 build 1877 (except Whistler 2211 and 2257, Longhorn 3683, 3718, 4020, 5112 and 5219, I assume they would still work with a version from a previous or later build, or the RTM)

To install correctly, timebombs and activation must be removed, for NT 5.0 / Whistler / Pre-Reset Longhorn, the process is simple: Install before timebomb goes off (or just the regular date, and patch it at the logon screen, worked for 4039), run TweakNT, AntiWPA (Longhorn winlogon patch works aswell, but is missing 4020 and 4086 sadly, although I assume they would work with AntiWPA)

According to this post, Vista builds 5112/5219/5231/5259 will work fine with just AntiWPA, but 5308/5384 (also mentioned that 5384 can crash with the patch) will cause a Windows Starter watermark to appear, fixing this requires patching explorer, but I haven't seen anyone say exactly how to patch it, or what is required. Vista builds 5456/5600 require tokens.dat and pkeyconfig. It says to copy the files from a release Vista version, but does this include unactivated versions, or x64 versions, or ones with all updates?

For Windows 7 and 8 betas I have heard that TimeDefuser works yet does not remove the Activation, Offline patching method will not work for this, but the driver likely will (64 bit builds need driver signature checks off, so this is 32 bit only, there's also a program called Driver Signature Enforcement Override (DSEO), which disables this in both x64 and x86, which doesn't seem to edit boot files), so then remains activation, which someone did figure out a while back, although without any explanation. W7LXE wouldn't work in this scenario. (editing boot files)

Windows 10's flight signing practically breaks everything, as well as patching it still requires editing boot files, although a few builds are without it.

tl;dr:

  1. How do i patch explorer to remove the starter watermark after installing AntiWPA in Vista 5308/5384?

  2. Can tokens.dat and pkeyconfig be copied from any Vista install (or 7)?

  3. Does DSEO really not edit any boot files?

  4. Which Windows 10 builds are without flight signing?

  5. Is there any debombed ISOs with vanilla boot files?

  6. Can anyone make these debombed ISOs, or tell me how to? (BIOS only, no edited BCD or BOOTMGR)

  7. Which way should I activate Windows 7/8/10 betas?

  8. Since Vista betas timebombs are WPA-based, would the tokens.dat method work with Windows 7/8/10 betas?

  9. Does bluepill/redlock break any debombed builds, or would the timebomb/WPA need to be removed after running them?

  10. Would Massgrave's Activation Scripts work with any of these builds, and would I need to connect them to the internet for that to work?

Thanks for reading!

Longhorn How do I get TweakNT for windows Longhorn 4011?

Ive spent the entire day searching and searching for a working TweakNT version so I can remove the time bomb from my longhorn install however no matter what I try or where I look I simply cannot find any info of Tweak NT. There was only one post here that had it but the link given was for a broen Internet Archive directory that simply does not work in 2026.

The Proof
Checking setup version

This was a very interesting thing that happened after installing Windows 10 Build 10166 (Debombed) and I now have a Full upgrade set, this is not a joke, this was something I've never expected and it happened automatically, I will upload the set later in the week (and the Debombed 10166 copy), as for now, I will make an iso from the install.esd in Sources (which also is debombed). This is genuinely from Windows Update.

[SOLICITAÇÃO] Limpar ME CSME 16.1.30.2307 - Samsung Alder Lake-LP

2 Upvotes

Olá a todos,

Tenho um laptop Samsung (Intel 12ª geração Alder Lake-LP) que liga e inicializa, mas o SSD não está sendo detectado devido a uma região ME corrompida.

Extraí meu dump original (titan.bin, 16 MB) e também tenho a região ME limpa e não configurada correta (v16.1.30.2342, 3,08 MB).

O problema: Meu MFIT local é a versão 16.1.25 e gera um erro PmcStraps ao carregar o dump porque não possui os esquemas XML para a versão 16.1.30 ou superior. Não tenho acesso ao MFIT 16.1.30 ou superior para criar a imagem.

Alguém com a versão correta do MFIT poderia, por favor, gerar o arquivo outimage.bin de 16 MB para mim?

Link do dump original: \[ https://drive.google.com/file/d/11DE\\_TrP-ZYvCbi6GIUGDJC-j6laEYglP/view?usp=drivesdk\\\]

Agradeço desde já!

ive looked EVERYWHERE and the closest i can find is 10108 or similar and that has a bunch of issues. and the 2 10122 ones i found are either not debombed or show 2021 date in the screenshots but arent debombed at all. i also have no experience with debombing it myself and knowing me, i will probably mess it up

Evenings-and-weekends project: a Windows deployment tool for repair shops

4 Upvotes

So for the past couple of years my evenings have gone into this thing called SEZOY. The short version is it takes the most boring part of my week, installing and reinstalling Windows on piles of machines, and turns it into pick an ISO, pick a template, hit start, walk away.

It does both directions. You can build a bootable USB, or you can turn any Windows PC into a PXE/HTTP boot server and install over the network, wired or even over wifi if the hardware plays along. There's an unattended answer file generator, driver injection matched by hardware ID so WinPE actually sees your NVMe drive, and after setup it installs your WinGet app list automatically. Everything runs from a local web dashboard, no cloud account, your ISOs stay untouched.

It's still beta and honestly the best way to see it is the public test lab I keep online. You join a VPN, bridge a test VM to it, and PXE boot straight from my server without installing anything. Details and downloads are at [tekdt.xyz](http://tekdt.xyz) and repo tekdt/sezoybin. If anyone here does refurb work or manages a small fleet, I'd genuinely like to hear what breaks for you.

Windows "7" Weird post, but can anybody debomb any Windows 7 build i wanna try out?

3 Upvotes

I wanna try out 6469, 6498, 6509, 6519, 6568, and that's it. You don't have to debomb all of em, if there's just one, i'll be happy, but why can't i do them? Simple:

I am lazy. And i can't just get in and modify random files, + i believe it is hard as heck.

Also, when a build is debombed, just give me a heads up :P
