Windows 10: I activated my Windows 10 through [removed]. How do I deactivate it so I'm not longer...

Hi there,As the title says, I activated my Windows 10 through <removed>because I wanted to get rid of the annoying watermark in the corner.Stupidly I checked the legitimacy and safety of the method AFTER running the script to activate windows and connect to their KMS and now I'd rather have the watermark again honestly.I tried to remove the key by opening command prompt as admin, run slmgr /upk, slmgr /cpky, slmgr /ckms, slmgr /ckms-domain and /slmgr ckhc for extra measure.Upon checking Activation settings for windows, the red message "We can't activate Windows on this device as we can't

Windows 10 deactivated after mobo replace.

Yes, he will have to redo activation. And he can do that using a spare HDD. He could even do that with just an empty partition on the existing hard drive.

Sequence of events:

1. Change of MOBO triggered a change in hardware configuration which deactivated WIN 10 on HDD A.
2. Remove HDD A from new MOBO and put blank HDD B on it.
3. Install WIN 8 on HDD B. Ensure it is activated. Upgrade to WIN 10. Ensure it is activated.
4. Now the new MOBO hardware info is stored on Microsoft activation servers.
5. Remove HDD B and reinstall HDD A.
6. The existing Windows 10 on HDD A will activate based upon the hardware info stored on Microsoft activation servers in step 4.

Windows 10 recalculates the hardware configure each time it starts. If it is the same as last time, it stays activated. If it is different than last time it deactivates - and if it doesn't find the new hardware on Microsoft activation servers, it stays deactivated.

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Why has Windows 10 slowed my computer so much?

If you upgraded to Win10 with MBAM installed, it's very possible that the OS upgrade messed up something with MBAM.
(It was/is M$ "best practices" to temporarily uninstall your AV, AM and other security programs before upgrading to Win10, to minimize the chance of such corruption.)

Either way, for starters, I suggest a proper, clean MBAM reinstall.
I suggest carefully following ALL of the steps here: MBAM Clean Removal Process 2x.
Pointers:

• Please be sure you have your license info handy before you start
• Please be sure to deactivate your account before you uninstall (dashboard > "my account" > "deactivate")
• Please be sure to reboot when prompted by the removal tool
• It's a good idea to reboot again after the reinstall

Please let us know if that resolves your issue.

Thanks,
