When you distribute Version 2019 to your users, in addition to providing them with the installer and the serial number, you must also provide the Product Key request URL as the Product Key is required during license activation.
I have problems to understand what is the difference between the serial number of a certificate and its SHA1 hash.
The MSDN says:
Serial number A number that uniquely identifies the certificate and is issued by the certification authority.
So can I identify a certificate by its serial number, right?
Wikipedia says for the hash:
Thumbprint: The hash itself, used as an abbreviated form of the public key certificate.
So the hash identifies the (e.g. RSA) key.
I currently do some research on Android app certificates and I found some interesting certificates:
And there are a lot more which share the same serial, but have different hashes.
So there can be a certificate with different key? Who is actually creating the serial number when creating a certificate for an Android app? For the hash it is clear, but can I create a new certificate with the same serial number as another cert?
Can I be sure that a certificate with the same serial number was created by the same person?Vilican
In a certificate, the serial number is chosen by the CA which issued the certificate. It is just written in the certificate. The CA can choose the serial number in any way as it sees fit, not necessarily randomly (and it has to fit in 20 bytes). A CA is supposed to choose unique serial numbers, that is, unique for the CA. You cannot count on a serial number being unique worldwide; in the dream world of X.509, it is the pair issuerDN+serial which is unique worldwide (each CA having its own unique distinguished name, and taking care not to reuse serial numbers).
The thumbprint is a hash value computed over the complete certificate, which includes all its fields, including the signature. That one is unique worldwide, for a given certificate, up to the inherent collision resistance of the used hash function. Microsoft software tends to use SHA-1, for which some theoretical weaknesses are known,
but no actual collision has been produced (yet). A collision attack on SHA-1 has now been demonstrated by researchers from CWI and Google.
(The thumbprints you show appear to consist of 40 hexadecimal characters, i.e. 160 bits, which again points at SHA-1 as the plausibly used hash function.)Thomas Pornin

The thumbprint is the sha1sum or sha256sum of the certificate in its binary .DER format. That is, from a Unix terminal you run:
The hexademical output of that command is your thumbprint. It is also called the fingerprint. Try it, and you will see.

You must have a valid product key to install Windows. If you no longer have the product key to your Windows operating system, and it isn't installed and working on your computer, but you still have the original disc, you may be able to request a replacement product key from Microsoft for just $10, so you can install the software on your computer.
Your only alternative is to buy a brand new copy of Windows, so it won't hurt to at least attempt to get an inexpensive replacement from Microsoft.
If you lost your product key, but Windows is still installed and working on your computer, use a free key-finder program to extract the key from your registry.

How to Request a New Windows Product Key
Follow these instructions to request a new Windows product key for Windows 10, Windows 8, Windows 7, Windows Vista, or Windows XP:

Determine if your copy of Windows is a retail copy or preinstalled copy:
Retail: Your copy of Windows is a retail copy if you or someone else purchased Windows as a standalone software package and then installed it on your computer. Your copy of Windows might also be a retail copy if it came on your new computer and your computer came from a small builder. Proceed to Step #3.
Preinstalled: Your copy of Windows is a preinstalled copy if it was already installed when you purchased your new computer. This is likely the case if you have a major brand PC and you've never installed a new copy of Windows yourself. See Step #2.
Other: If you purchased or were given a copy of Windows from your organization, business, or another group, see Step #2 but contact the issuing group instead.
Contact your original computer manufacturer directly to request a new product key if Windows was preinstalled on your PC. If your computer manufacturer is not able to assist in issuing you a replacement product key for Windows, proceed to Step #3. Microsoft may still be able to help.
Call Microsoft at 1 (800) 936-5700. This is Microsoft's Paid Support telephone number. Microsoft's site advises that support calls to this number incur a $40 to $60 charge. However, you are not charged this amount for a call about a new product key.
Follow the auto-attendant prompts appropriately so you can speak to a customer service representative about your missing product key.
The Microsoft representative will take your contact information—your name, telephone number, and email address—and then ask for details about your problem. Tell the representative that you have your original Windows installation CD/DVD but need a replacement product key.
Answer the questions the representative asks. They may include requests for specific details about your Windows installation disc, such as the numbers around the inner circle of the CD/DVD and details about what words or images may or may not be on the disc. Microsoft asks these questions to verify that the installation disc you have is not pirated.
Microsoft takes your credit card information after verifying that your installation media is genuine. This new Windows product key should cost you $10, plus tax.
The Microsoft representative then reads you your new product key and asks that you enter it into the activation window to be sure it creates a new installation code.
The representative then transfers you to the telephone-based activation center to complete the Windows activation process.

If for some reason you're not able to get a replacement product key from Microsoft or your computer manufacturer, and your copy of Windows is not currently installed (excluding you from the product key-finder method), then your final course of action is to purchase a new copy of Windows.
You can buy Windows 10 and Windows 8 directly from Microsoft or popular online retailers such as Amazon and Newegg. Older versions of Windows, such as Windows 7, Windows Vista, and Windows XP, are harder to find, but you can usually find copies at reputable sellers on the internet.
