Sigh.  That "professional" has not served you well.


The error-message refers to an "activation server" on the local network, but no such server exists on your home network.


The version of Windows that was installed has two methods for "activation":


  • KMS -- communicating with that "activation" S(erver), to M(anage) the product K(eys).
  • MAK -- multiple activation key.

The 'MAK' activation allows all the computers inside a company to be licensed to use the same product-key.

It allows Windows to be installed once, and then "disk-cloning" can be used to make copies for all the other licensed computers.


That version of Windows, with its product-keys, is NOT allowed to be used "outside" of that one company.

Shame on that (alleged) professional, for "leaking" it.

Or, even worse, from downloading from the Internet a "leaked" copy, and then foisting it onto you.



Your computer: HP Pavilion 500-164 Desktop PC Product Specifications

was originally shipped with Windows 8, with RAM:

  • Amount: 8 GB
  • Speed: PC3-12800 MB/sec
  • Type: DDR3-1600

So, presumably, it shipped with the 64-bit version of Windows 8, because the 32-bit version could only use 4 GB.


What should have been done is to reinstall the same version of Windows 10, not the 'Pro' version.


Because your computer was running Windows 10 Home, you were granted a "digital entitlement" to reinstall the same operating system, at any time, at no cost to you, onto the same computer.


Download Windows 10, for free, via:

and follow the instructions to create a "bootable" copy of the Windows Installer, either onto one 8GB USB memory-stick or onto one DVD-recordable disk.


Boot your computer from that media.

When prompted to enter the 25-character product-key, click "I do not have one".

Windows will continue to install.

After rebooting, when Windows connects to the Internet, it will automatically "activate", to become a "genuine" copy of Windows 10.

Then, run Windows Update, to apply the latest security-fixes.


Or, if you want to restore Windows 8, see:  Software and driver results for: HP Pavilion 500-164 Desktop PC


Order Recovery Media-CD/DVD/USB

USB - Windows 8 64-bit Recovery Kit

System Recovery Kit for Consumer Desktop

Order Media

to purchase a copy of the original factory-installed operating system.


Installing from this media will include some extra HP application software.

Then, you can use the above Windows 10 Installer to "upgrade" from Windows 8 to Windows 10, which should retain those extra application software programs.
