    Lets Encrypt certificate fix for old OS.reg
    Code:
    Windows Registry Editor Version 5.00
    
    ; a non-convoluted fix for Let's Encrypt certificate f**kup by AveYo
    ; should work instantly, just restart your browser (tested in vanilla windows 7 sp1 with ie8 so it should be fine elsewere)
    
    ; Tho generally, these things are meant to be convoluted, for you to manually do the work of importing a new certificate,
    ; checking if it's digitally signed and valid, all that jazz
    ; Make a habit of familiarizing yourself with these things, it's not rocket science.
    ; The alternative is to trust people on the internet. For example, the below certificate,
    ; while being a verbatim export of isrg-root-x1-cross-signed.der, could very well be modified by a malicious actor

    Just save as reg (also attached) and double-click to import.
    Tho generally, these things are meant to be convoluted, for you to manually do the work of importing a new certificate, checking if it's digitally signed and valid, all that jazz
    Make a habit of familiarizing yourself with these things, it's not rocket science.
    The alternative is to trust people on the internet. For example, the above certificate, while being a verbatim export of isrg-root-x1-cross-signed.der, could very well be modified by a malicious actor.
    [edit: added above disclaimer to the reg file as well]

    I have NO WORDS to thank you! It will be extensively tested in the following days, in case more complaints emerge.
