Vista OEM Activation Crack: Hack to Modify BootMgr to Activate Vista
To activate Windows Vista with OEM activation hack, the BIOS of the system must support and have an ACPI_SLIC table in the system BIOS that also has a corresponding valid Windows marker in the same ACPI table. To achieve this objective, there are plenty of ways to crack the BIOS to activate Vista, such as boot loader based BIOS emulator Vista Loader, driver based BIOS emulator Paradox OEM Emulation Toolkit or physically modify the BIOS by flashing SLIC-included BIOS mod. You can now also perform Vista OEM activation crack by directly modifying BootMrg, the boot loader for Windows Vista, to emulate OEM BIOS.
Features of Vista BootMgr OEM Activation Hack
- Does not modify and change the MBR (Master Boot Record).
- Better support OEM brand like DELL where BIOS can’t be modded to including the SLIC hack. As long as the memory where the RSDT table resided can be used and written, then it’s possible to crack Vista activation. (It’s possible to use HWDirect to test if the RSDT table can be written.)
- Support 32-bit and 64-bit Windows Vista versions (x86 and x64).
- No actual physical flashing of BIOS needed. This hack is another software based BIOS emulator.
Guide to Modify Vista BootMgr
A Chinese hacker, gkend, has wrote a program that will modify the BootMgr to add in SLIC of the manufacturer brand you selected, and install the corresponding Vista OEM product key for automatic activation of OEM editions.
Download VistaBoot.rar where inside contains VistaBoot-en.exe V07.0526 (replaced V07.0519 with compatibility patch) and SLIC data from various OEM vendors and respective OEM digital license certificate.
Installation Tutorial
- Install Windows Vista.
- Run Vistaboot-en.exe with administrator privileges by right clicking of VistaBoot-en.exe and select “Run as Administrator”. Else you will get the “Cannot modify the file attributes.” error.
- In the Vista Boot window, select a SLIC file for the brand you prefer, and system boot drive where the Vista is installed.
- Click ‘Modify BOOTMGR’ button.
- Restart the cmputer.
- If the Windows Vista is not installed from an OEM DVD (mean the Vista version if not of OEM type), run Command Prompt (cmd) as administrator.
- Type the following command:
slmgr.vbs -ilc oem_brand.XRM-MS
Replace oem_brand for the actual OEM vendor name that you use in emulated SLIC table, such as ASUS, Dell, HP, Lenovo, Sony, Acer and etc. For example, when emulating an ASUS SLIC, and the ASUS certificate file is named ASUS.xrm-ms, then type the following:
slmgr.vbs -ilc ASUS.XRM-MS
Ensure that the path to the file is correct too.
- Verify the activation status. It should b activated.
If you having problem to modify the BootMgr due to permission error, try to take ownership and grant full control permissions to yourself. To see BootMgr file which is hidden by default, click on “Organize” in Windows Explorer, then select “Folder and Search Options”. Click on “View” tab, then select “Show hidden files and folders” setting under Hidden files and folders section, and also clear the check mark (unselect) on “Hide protect operating system files (Recommended)”. Click “OK” when done. To clear the Read-Only property on BootMgr, right click on BootMgr and then select “Properties”, unselect the “Read-only” attribute and finish by clicking “OK”. If you still having error, try to use other tool such as WinHEX to remove the system, hidden and read-only attributes from BootMgr, or you can run the following command in elevated command prompt:
attrib -r -s -h c:\bootmgr
Replace C (drive) with appropriate boot drive letter.

April 21st, 2008 09:35
same error as Korn
“the file size not ok”
is this because of sp1?
April 15th, 2008 14:09
It Doesn’t work.
It said “The file size not ok”.

Follow up to my comment.
Nah… don’t bother with this method. It worked, sure. Then, I tried by running autoupdate and the next day, it’s deactivated and it seems MS has patched the boot manager to a new size. So, this method does not work anymore.
I’m now back to the grub method… hate the text but hey, it’s the most reliable. Frankly, I hate Vista but had no choice bcoz there’s no bug-less drivers fro this HP lap… So, had to crack vista just to run vmware and opensuse on it.. haha.

will this method outstand sp1 as well, or do i have to flash a moded bios?

Where can I get the SLIC for am Abit mother board?
March 18th, 2008 03:15
It worked!
Before following the steps in the installation tutorial above, first, install Vista with the appropriate OEM key. If already installed, just change the key. You’ll get error but just ignore.
Get into elevated command – right click cmd and run as administrator.
Type “CD \”. Then, type “takeown /a bootmgr”. Then type “cacls bootmgr /p BUILTIN\Administrators:F /e”. Leave the cmd window open.
Then follow the instructions above up to number 8. Don’t follow the “attrib” part – not needed. Then, do the following from the elevated cmd, type “cacls bootmgr /p BUILTIN\Administrators:R /e” to restore back.
Make sure you have no CD inside the cdrom and type “shutdown -r -t 0″ to reboot now.
Should be ok now. I got it to work as Home Premium as well as Ultimate for the HP version.

Just a follow-up,
By saying in the 3rd paragraph in the last post:
“Although vistaboot did successfully modified bootmgr, the Dell machine couldn’t load Vista.
It looks like that the bootmgr was not proparly recognized and then XP’s ntldr ran instead.”
I mean that XP booted without going through the selection window, as you always see “Earlier version of Windows” or “Windows Vista” at running.
Hopefully it makes myself understood

I tried this on my Dell Optiplex GX620 with XP Pro and Vista Ultimate x64 dual-booted.
As happywithcrack pointed out, I had to go through “takeown” and “cacls” to let vistaboot modify bootmgr.
Although vistaboot did successfully modified bootmgr, the Dell machine couldn’t load Vista.
It looks like that the bootmgr was not proparly recognized and then XP’s ntldr ran instead.
One possibility is that at the end of the modication of bootmgr by “takeown” and “cacls”, I was not able to change ALC of Administrators from “F” to “R”, while all the other entities were correctly modified back to their original status of access authority.
Anyways, I suspect that the Dell Optiplex GX620 does not have SLIC2.0 table within the BIOS. (Maybe because it’s pre-VISTA era PC?)
I suspect so because I as first tried installing VISTA ultimate x64 by using genuine Dell OEM DVD.
Or simply Dell’s pre-vista era PCs are not possible to alter BIOS, let emulate OEM table or allow any workaround??
The last thing I can is simply buying Retail VISTA….

Just run DBAN CD and re-install Vista afterwards from your Vista disk after backing up your Ubuntu, Redhat and other GNU-based wonderful partitions you have residing on your hdd. You will have your Vista right back to factory install. The annoying thing is: Now you have to go and add GRUB to the master boot record again so you can boot all of those other real bug free operating systems again what a damn mission. Vista is like the rainforest it looks so nice but it’s full of deadly bugs and nasty surprises.

I had access denied errors for bootmgr and the attrib command did not work
However,
use the “takeown” command, followed by cacls.
Using x64, this gave me access to bootmgr. I tried a ridiculous amount of techniques before finding this, even going into safe mode (which did not work)

put a windows vista cd in the cdrom then boot the computer..but don’t boot from cd. Computer will start up.

Hello
I’ve followed the instructions. The operation is “success”.
But when I restart the computer, Vista doesn’t boot. The screen stays black.
Some idea?
