I tried to upgrade my PC running Win 7 to Win 10. My PC has met all the prerequisites (checked by Win 7 itself) and started to upgrade. The progress circle was progressing. However, all of a sudden, it gave me a error of "PAGE_FAULT_IN_NONPAGED_AREA" and rolled back to Win 7. And the Win 7 said: cannot install Windows 10, found one error C1900101-30018.
Does anyone know how to fix this? I know some of you might suggest me to reinstall Win 7 and upgrade but I just don't want to reinstall all those software installed on Win 7.
