STATEMENT OF PROBLEM:

I have an old but high end with 17-inch screen (HP) laptop which still runs Win11 25H2 very well.  It has a legally purchased Office 2019 Home & Student Ed. installed and registered officially to my Microsoft user account. For the purposes of this question, let’s call this setup DT-1 (the 17” screen HP laptop) and the Microsoft Account User-1 where it is officially registered with Office 2019.

My friend is running Win11 on a Microsoft Surface laptop with Office 202x – legally purchased and officially registered. For the purposes of this question, let’s refer to this second setup (Surface laptop) and MS user account as  DT-2 and User-2 respectively.

I am retiring DT-1 as the old owner and am giving it to User-2 so he can have a larger screen size and still run the same Office software (mostly WORD and PPOINT).

QUESTIONS:

Q1 – When I give DT-1 to my friend can he (should he) register DT-1 to Microsoft Account as the new owner – using his existing User-2 MS Account -- and continue to use the Office 2019 software on it?

If so, what procedure(s) must he perform to do this properly and legally (as new owner but same device).  Do I (the old owner) have to “Remove device” DT-1 first from my MS Account User-1 BEFORE the new owner can “re-register” it to his MS Account User-2?  What is the proper sequence of actions to do this?  Kindly provide specifics (what program to run, and from where, etc.)

Q2 – After DT-1 is “Removed” from MS Account User-1 and “re-registered” under MS account User-2, can Office 202x be installed on DT1?   The total number of devices that installed Office 202x under User-2 account is only one: the Microsoft Surface laptop.

The intent is to stop using Office 2019 (from old owner) and start using Office 202x (with new owner). The new owner – User-2 – has purchased a legal copy of Office 202x on DT-2.

What are the steps, procedurally to perform in order to achieve the 3 actions described above?

Would be grateful for any tips and guidance.

Thanks in advance.
