Windows 10: Using clean windows 10 install to remove Expiro root kit

Bought a brand new computer and on start up, windows defender repeatedly popped up saying it was putting various Expiro files in quarantine. Used windows 10 inbuilt reset function to restart/reinstall windows 10 and wipe everything. Windows defender doesn't say anything, but on further inspection it's because windows defender isn't even installed/is disabled.Computer I bought: https://www.amazon.ca/dp/B0DTTL4W77?ref=ppx_pop_mob_ap_shareInstalled an old 1060 GPU I had laying around. No other changes.Tried multiple things to get windows defender back from the below article, nothing worked. Also

Is it time for Windows 10 already?

Clean Install Workaround for Vista

You may remember this news story on techPowerUp! a couple of days ago relating to the lack of clean installs when using the Upgrade Editions of Vista, which required an old OS to be installed. However, Paul Thurrott has managed to find a workaround for this issue, which ironically lets users do a clean install Vista without any previous version of Windows, albeit a little tedious. Here are the steps:

• Boot from the Windows Vista Upgrade DVD as normal
• When prompted for a product code, leave this blank
• Select the version of Vista you have purchased and let Vista install
• When you boot to your desktop for the first time, run the Vista setup from Windows
• This time enter your product key
• When asked whether you want to do an Upgrade of Custom install, select custom and choose a clean install
• Windows will now install for a second time and you should be able to activate it

Remember, these steps are only advised for use in order to achieve a clean install of Vista, it is only legal to use the upgrade editions if you have previously purchased the appropriate version of Windows.
