PC : Aspire T3-715
OS : Windows 10 home 64b. 1909
Current situation:
The PC starts, & BIOS available, & can rain Win10PE.
Can not login Windows, can not run any option in WinRE, can not run OEM Recovery by hot key or DVD.
The only option now is reinstall OS.

Question 
1. Is product key a MYST for the reinstall ?
2. How to find the product key since the PC can not boot into Windows?

Thank you.

    Yes, ignore them. :) Your system is licensed to run the OS and the key is embedded in the BIOS, so after you do the install it will validate for you as soon as you connect to the internet. The only time you might have an issue would be if you tried to install a different version of the OS, so W10 Pro instead of W10 Home.

    Hi,
    1. Yes, you need the product key but it must be embedded, normally the system activates automatically.
    2. You could find the product key using CMD, please find the method in the middle of the page in this link:https://www.groovypost.com/howto/find-your-windows-10-product-key/

    The link leads to the use of Produkey.  I used it but failed.
    I ran Produkey in a Win10PE since the PC could not boot into Windows.  
    Produkey found the product key of the Win10PE, not Windows 10 on C: d

    I didn't think there is any way to find out now because your window is not working anymore 
    Is it preinstalled window?

    Window is corrupted, there is no other way find out product key.
    Did you have any other window system?
    You need to install fresh new window from Microsoft.

    I don't know about your laptop but in most of laptop product key is attached with motherboard or bios.
    If you are one of them, then your window will automatically activate when you installed new one.

    You don't need the product key  in order to reinstall Windows 10, the BIOS has it embedded and the reinstall will find it for you. Just make sure you are installing the same version of Windows, likely Windows 10 Home 64bit. Create yourself an install flash drive on another system, boot from that flash drive and install a clean Windows. You should be good to go, unless you find you need a driver or two from the Acer support site.

    Thank you, Mr. GAMING6698.

    "Is it preinstalled window?"
    Yes. It is.  I bought the machine with the OS preinstalled.

    Don't worry about your product key, it is embedded in your bios or motherboard.

    When you install new fresh window, window will activate automatically and install Window 10 home.

    Do you have any other window system?

    No. The Produkey did not fail.  The reason that it did not find the product key of my OS was because it was run in a Win10PE system, not in the system of my PC, and it found the product key of the OS of that Win10PE, not the product key of the OS of my PC.

    Produkey is very good APP.  The question is how to use it finding the product key of the OS installed in my PC.

    The possible problem is this :
    Microsoft might consider my OS pirate version since I did not register at Microsoft when I started using the PC.  So said in Microsoft Community.

    Do you know for sure that product key is not required for a clean install?

    Thank you.

    GAMING6698, thank you.

    "When you install new fresh window, window will activate automatically and install Window 10 home."
    It is said in Microsoft Community that Microsoft considers my OS pirate version because I did not register at Microsoft when I started using the machine.
    Is this true?

    "
    Do you have any other window system?"
    Yes. I do.  I bought 2 same T3-715 machines at the same time.
    One is crippled.  The other one is now in use.
    I can make Win10PE on this, the one I am using to do the Win10PE and reinstall.

    I want to be sure that my OS is legal, not to be considered of any terms of piracy.

    Thank you.

    "Download rufus and download windows 10 iso."
    Yes. Exactly what I did.  And had it reinstalled smoothly.  Product key was not even mentioned during the entire process.
    Thank you.

    I used Rufus before for reinstalling my XP many times.  The reinstall of Windows 10 by Rufus was smooth and easy.  Not a word about product key was mentioned during the reinstallation.

    Thank you.
