Windows 10: Windows 10 pro product key gone after factory reset

Hi, I bought a laptop with Windows 10 Home installed, later I upgraded it to Windows 10 Pro, I bought a digital key from a certified reseller - everything worked fine. Recently I wanted to give this laptop to someone else, so I made a factory reset, using an external pendrive with fresh Windows 10 Pro.After the installation, Windows is not detecting the Pro key, it only detects this old Windows Home key I got together with laptop.If I use a troubleshooting tool, it says I should change to Windows Home and I don't want that, of course.If I try to re-enter the Windows Pro key, get an error say

windows 10 key

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

 

Windows 10 activation problem after factory reset. Error 0xC004C003





See the windows is activated. And this is the screen which asks the product key. I can only skip this step if I boot from the dvd and select the clean install option.

"slmg /ato" returns Activating Windows core single language edition (a string of numbers and alphabets)
Product activated successfully.

 

How to factory reset Cisco 1700 Router

Hopefully I can help you here....its a very common thing to happen.


First, I take it you dont know the passwords for console access or telnet/ssh?

I will assume that these devices belong to you.

step 1. Plug a cisco console cable into a serial port on your pc
step 2. Plug other end into Cisco console port
step 3. Using hyperterm or putty or similar connect to the serial port
step 4. boot router, and make sure you clearly can see the output (this confirms you have good serial comms)
step 5. if this fails, adjust the comm port settings (9600, 8,1,n are the default)
step 6. now you have to do the only hard part...send the break command:

Break command list: Break Commands

Go down the list and match your OS and SW and try the sequence suggested.

If this fails several times do what I do: Install putty (free) and then to send a break so you can get into rommom just hit "ctrl-a b".
