Activation: Not Genuine, Windows Update Failing to Install (Errors)

Try this...

Please first try recreating Licensing Store.

Recreate the Licensing Store
Go to Start > All Programs > Accessories
Right-Click on Command Prompt and select Run as Administrator - accept the UAC prompt
Run the following commands in the Command Prompt window, using the Enter key at the end of each

net stop sppsvc
(wait until the service has stopped before entering the following lines)

CD %windir%\ServiceProfiles\NetworkService\AppData\Roaming\Microsoft\SoftwareProtectionPlatform
REN tokens.dat tokens.bar
net start sppsvc
slui.exe

After a couple of seconds the Windows Activation dialog will appear.
You may be asked to re-activate and/or re-enter your product key, or Activation may occur automatically.
If you are asked for your Key, use the one on the COA sticker on the machine's case

Reboot and Post back with a new MGADiag report.

(Note: the Line 'CD %win......\SoftwareProtectionPlatform' is all on one line - it may be broken in the Forum listing)

That almost always means that the tokens.bar file already exists - use the following command instead, at that point...
REN tokens.dat tokens.bar3 (change the character to a 5 if that also give the same error)

What error code is it giving you?

0xC004F050 usually means that you've misread a character - either C/G/6 or B/8 or Y/V are the most common, an O/0 is almost always a Q

Note that the following characters cannot be used - A E I L N O S U Z 1 0 - so don't bother trying unless you like the noise it makes :)

The current Key is the OEM_SLP Key - the manufacturer's 'master' key...


Computers that come pre-installed with Windows from large manufacturers usually come with two Product Keys.

OEM SLP: This is the key that came in Windows (from the factory). It works by connecting to a BIOS flag (the SLIC table) found only on computers from that Manufacturer. It also checks for the existence of proper matching licenses in the OS itself. Once it sees both, it self-activates every time the machine is rebooted.

COA SLP: This is the key seen on the sticker located on the side, bottom or in the battery compartment of your machine. This key is for use if the OEM SLP self-activation stops working for whatever reason.

In your case, the 0xC004F063 from the report indicates that the self-activation system can't find the built-in licenses that should be in the OS from the Recovery media - this is usually caused by doing a repair install or a clean install with retail media without also using the COA key from the sticker.
This should not affect the ability of the COA Key to activate the system normally.
I can't think why the system is not allowing you to even attempt activation unless either
1) there is a typo in the Key entry
or
2) the Key is for a different edition or version of Windows.

In the second case, we would normally see a message to that effect - but please check that the sticker is for Windows 7 Home Premium.

What is the full Model Number of the machine? (I know the Satellite S875D bit - but there should be some other codes after it)

In that case, I'm stumped
All I can suggest is that you ring your local MS Activation Center, and see if they can help - they may be able to either fix it, or issue you a new Key which works. The list of Centers is here... https://www.microsoft.com/licensing/...n-centers.aspx
