Determining the UEFI BIOS OEM Embedded System Locked Preinstallation Key

The OEM product key (SLP key) is hidden within the UEFI BIOS. In order to determine your product key, the RWEverything utility is recommended as it looks at the systems hardware to determine the Windows product key and not at the registry, meaning it does not give bogus results like other utilities:

To find out the OEM BIOS Embedded System locked Product Key, install RWEverything and then select ACPI Tables and the MSDM tab, copy down your product key.


Note no MSDM tab = No Windows 8.0/8.1 BIOS Embedded SLP key.

This key is classified as hardware (part of the motherboard) and so Microsoft will not be able to help you if this tab is missing.
Systems which shipped with Windows XP, Vista or 7 have no MSDM tab as these versions of Windows used a generic key for OEM SLP; you need to purchase a retail product key for these systems. Note if you have purchased a retail license for such systems there will be no MSDM tab.
If you have a systems which came with Windows 8.0/8.1 and no MSDM tab then you need to contact your OEM for a motherboard replacement or purchase a retail license. Its extremely rare for an OEM motherboard to lose its Windows 8.0/8.1 key but I have seen a few examples.
While this utility gives your product key. It should be noted that it does not give you the Edition of Windows 8.1 this product key is for however at least you can confirm you have an OEM product key. If you have tried the 5 “Editions” and they all reject your product key then it is likely you have a Bing Edition which Microsoft chose not to support with this tool.

How to Repair a Windows Corrupt Profile

How to Repair a Windows Corrupt Profile

By Chris Hoke, eHow Contributor – Original Post

When logging in to your Windows 7,Vista, or XP operating system, you may be creating a new temporary profile instead of logging in with your regular user profile. If so, Windows has a profile list error, caused by an error in your profile settings. The system attempts to fix the problem by loading a temporary profile. Fortunately, Windows typically backs up your profile settings so you can restore them by using the Registry Editor program.


  • 1 Click the “Start” menu button after logging in as the temporary profile. Type “regedit” into the “Search” field; then press “Enter”.
  • 2 Double-click to expand the “HKEY_LOCAL_MACHINE” key in the left pane.
  • 3 Double click “SOFTWARE”, “Microsoft”, “Windows NT”, “CurrentVersion”, and then “ProfileList”.
  • 4 Locate the two SID (Security Identification) keys that correspond to your user profile. Both keys are named “S-1-5-21-S” (where “X” is your security profile identification number), but one key has “.bak” at the end of the name. If you have more than one user on your computer, you can identify your SID keys by clicking on each key in the left pane and checking the user name data column located to the right of the “ProfileImagePath” field in the right pane.
  • 5 Right-click on your SID key name that does not end in “.bak” and click “Rename”. Type “_corrupt” at the end of the key name and press “Enter”.
  • 6 Right-click on your SID key name that ends with “.bak” and click “Rename”. Remove the “.bak” from the key name and press the “Enter” key.
  • 7 Close the “Registry Editor” window.
  • 8 Click the “Start” button, “Shut-Down” menu, “Log Off”.
  • 9 Log back into Windows with your regular profile to restore your user profile.
