If you’re using Acer computers, and the Acer motherboard or BIOS supports and contains SLIC and RSDT tables in ACPI module, and you can use the following hack or crack SLP 2.0 patch to activate Windows Vista installed with the leaked product key. You can check if the BIOS contains SLIC (Software Licensing Description Table) and RSDT tables by using Everest. If your BIOS if not currently supported, try to upgrade and flash the BIOS to latest version from Acer website.

SLIC in Everest
Once you confirm that your Acer motherboard and BIOS has SLIC table in ACPI, install Windows Vista with the following Windows Vista OEM product key:

Windows Vista Home Basic OEM: 762HW-XXXXX-XXXXX-XXXXX-XXXXX
Windows Vista Home Premium OEM: 2TYBW-XXXXX-XXXXX-XXXXX-XXXXX
Windows Vista Business OEM: 72PFD-XXXXX-XXXXX-XXXXX-XXXXX
Windows Vista Ultimate OEM: 6F2D7-XXXXX-XXXXX-XXXXX-XXXXX

After install, boot up and log onto Windows Vista, download the following file:

acerslp2.xml or Acer.xrm-ms.

Then, right click on Command Prompt icon and select “Run as Administrator”, or press Windows + R keyboard shortcut to launch command prompt window. Type the following command and press Enter:

slmgr.vbs -ilc <path>\acerslp2.xml

or

slmgr.vbs -ilc <path>\Acer.xrm-ms

Replace <path> with the location where you place the acerslp2.xml or Acer.xrm-ms file downloaded.

If you have already installed Windows Vista, change the product key with the following command to the above product key:

cscript \%windir%\system32\slmgr.vbs -ipk 6F2D7-XXXXX-XXXXX-XXXXX-XXXXX

or

slmgr -ipk 6F2D7-XXXXX-XXXXX-XXXXX-XXXXX

This will activate OEM version of Windows Vista (or Windows Vista as OEM edition) once the digital certificate is loaded.

Note that you can use any Windows Vista DVD media to perform the installation, be it retail or OEM DVD, as the only different between them is additional 2 files for OEM release where one of them is XrML Digital License file, an OEM certification file, which will be installed by slmgr -ilc command.
