Windows 10: Is my Windows's license key reset after downgrading Windows to 1909?

Hello,

So I've been considering to downgrade to 1909, but I'm not sure if it's a really good decision. Will my license key get reset if I downgrade it? Also, what's the difference between 1909 and 20H2? Thank you.

:)

 

Product Key not valid for downgrade

The problem is Microsoft never handled it.

Downgrade rights is handled by Lenovo, etc.

This is the information I saved before Microsoft pulled it:

Here is the information about Downgrade rights. It is an old Microsoft link which they removed but the information still apples>

Device Partner Center

Downgrade rights for Windows software
The following OEM versions of Windows software are eligible for downgrade rights.

[table][tr][td]Windows 10 Pro includes downgrade rights to:

• Windows 8.1 Pro
• Windows 7 Professional

[/td][td]Windows 8.1 Pro includes downgrade rights to:

• Windows 7 Professional
• Windows Vista Business

[/td][td]Windows 7 Professional and Windows 7 Ultimate include downgrade rights to:

• Windows Vista Business and Windows Vista Ultimate
• Windows XP Professional, Windows XP Tablet PC Edition, or Windows XP x64 Edition

Note Other OEM Windows 7 versions (for example, Windows 7 Home Basic and Windows 7 Home Premium) do not include downgrade rights.[/td][/tr][/table]

Note downgrade rights are only available as long as Microsoft provides support for that earlier version,
as outlined in the
Windows lifecycle fact sheet.

Steps for an end user to downgrade Windows software
To downgrade eligible Windows software, end users must:

• Purchase a PC preinstalled with Windows software.
• Accept the Microsoft Software License Terms.
• Perform the downgrade process to the eligible downgrade product using the media/key from a genuine, previously licensed OEM or retail product.

That's why I advise you to contact Lenovo.

 

Windows XP Downgrade

I'm pretty sure that no key = no Windows. If you want to downgrade, you need to put the Windows 7 disc in, then get up to the point where it asks which HDD to install it to. Format the drive, then shut down. Put in XP disc and you'll be good to go.

 

Question On OEM Windows clean install......

"Flavors" of Windows licenses

Windows can be a little "odd" about license keys. There are at least 4 categories:

• Retail
• OEM
• Volume (electronic download)
• Corporate (no key needed)

For guaranteed success, the license key and media should be in the same category. If you have retail media, you may not be able to install it using an OEM or Volume license key, even though the key is valid for that version of Windows. *Wtf :wtf: Apparently, this is part of Microsoft's anti-piracy scheme (i.e., all customers are guilty until proven innocent).
