Windows OS Serial Key Lost For HP Pavillion dv6000

[Srikant01]

Hi,

My laptop is HP Pavilion dv6000, purchased in USA, I came back to India, unfortunately my windows serial key at the back of my laptop is lost(worn out) due to usage, so I'm running this on another version of windows vista.

How can I know the serial key that would enable my laptop to be using original windows software that was pre-loaded at the time of purchase, instead of using the counterfeit version of vista.

Can HP team can restore my original windows product key, that was shipped at the time of purchase, if yes can I freely upgrade my OS to windows 10 version since my laptop was shipped with Genuine Product Key?

Please help me in solving this software issue so that I can get back my Genuine Windows Product Key and if possible upgrade to windows 10.

IF the PC is still running the original HP Win7, then you can download this utility to see if it can retrieve the product key: Download Windows OEM Product Key Tool 1.0.0.1 

If that does not work, here is an alternate utility: Showkey - Windows 10 Forums

Hi Team,

I'm able to retrieve the key but unable to install the key and upgrade my software to the genuine/original version.

I'm getting the following message.

Code -

0xc004E003

Description -

The Software Licensing Service reported that license evaluation failed.

Sorry ... I've been out ...

Software that comes preloaded on OEM PCs is nearly always a trial version -- and that has a limited lifespan.

If you try to reinstall that same software after the original trial period is over (typically 30 - 90 days, depending on the prodjuct), you will the error message that the license has expired.

There is nothing that can be done for expired software at this date.
