Windows 10: ACTIVATION LOST/MISSING PRODUCT KEY

Since updating Windows 10 to version 20H2, I have lost product key and Windows no longer activated. I got original product key when purchasing this ASUS laptop about 4 years ago. Also have FLTMGR.SYS error and a host of other problems. Computer is a mess so can barely use it!I joined Windows Insider and updated once. Now it reports an error and won't do anything. I assume this is due to lost product key / Activation.I cannot get anyone at Microsoft to speak with!!!! Very frustrating to say the least. NEED ASSISTANCE

:)

 

Lost Windows Activation Product Key

I recently lost my Windows 10 pro Activation product key and now Microsoft wants me to activate my windows but now i dnt have any product key please suggest me the way i dnt want to lost my all data...

 

Activate windows 10 after re-installing (I have lost my product key)

I own a Lenovo T430 laptop. In 2017, I installed Windows 10 using my original Windows 7 product key. Unfortunately, I cannot find that product key anymore. I need to re-install windows 10. Will it be automatically activated after the installation, if I skip the step of asking the product key during the installation?

In my opinion, I believe that my laptop will have a digital entitlement stored on the Microsoft Activation Servers and this will not be a problem. Is that true?

If not, please suggest me a solution or a workaround.

 

Missing Product key

Thanks

+1 for you

I'd forgotten / lost the old W8.1 key I had on my system after upgrading to RTM - anyway it works fine on W10 too.
