Windows 10: how re activating windows after changing hard disk

HI,I purchased a laptop with windows 7 Home Prem OA. after that I upgraded it to win 10. Six months ago I changed my systems hard disk. the technician changed hard disk and re installed windows 10. but last few days a massage appearing on screen is "Your windows will expiring soon, please activate". I give my windows 25 digit key. but it is not working. what is the reason. and what can I do for re activating windows. please help me.

:)

 

Windows activation, problem anticipation...

I bought a hard-disk to replace the faulty one in my Pentium 4 rig, which has OEM XP Home.

Now the last time I did a clean XP install I had to call MS and they gave me automated numbers to input to re-activate.

Just in case, that this time I have to speak to a human, will they be accepting to re-activate if I tell them (the truth) that I have changed the hard disk?

Or would you suggest something else? *Oh Well hwell:

Thank you.

 

External Hard disk contents are not visible.

Hi Pranoti,

For us to narrow down your concern with your external hard disk, we would like to know the following:

• Were there any changes made on your computer prior to the issue (e.g., updates, software installation)?
• To make sure that we have not missed on anything, what troubleshooting steps have you done so far?
• Do you hear any clicking sound when connecting your hard disk?

In the meantime, we suggest that you update all your device driver.

We look forward to your response.

 

Windows 10 Enterprise fails to re-activate after hard disk replacement

The system is a laptop where the single hard disk failed and was replaced. Unfortunately, there was no recent, viable backup of the hard disk that could be used to restore it.

A successful clean install was made from en-gb_windows_10_business_edition_version_1803_update_jul_2018_x64_dvd_12613160.iso.

The first login used my Microsoft Work or School account but I was unable to activate it from that account.

I then created a user with my Microsoft Account (which uses the same email address) but was unable to activate it from that account either.

The laptop has a firmware-embedded activation key. It appears in the devices list for my Microsoft Account and also appears in the devices list in the Azure Active Directory which we receive as part of Office 365.

It is a commodity laptop that was supplied with Windows Home installed; upgraded to Windows Pro using Get Genuine; and upgraded to Windows Enterprise with an OS upgrade using a product key. It was regularly updated before the hard disk failure.

I had anticipated that re-activation after the hard disk replacement should have been simple!

Any pointers to where I might be going wrong? Or suggestions as to how to diagnose this? I'm a volunteer systems administrator for a Museum (non-profit / charity) and this is outside my comfort zone.
