So, Windows 10 released with all of its pretty new features and you tried to download it, except you couldn't because you kept getting hit with an error that was a set of numbers almost entirely too long to remember (80240020). Well, don't you worry about that pesky error, there's a way to get rid of it!
Redditor Losemind has come to save the day!
Here's how to download Windows 10 after getting hit with installation error 80240020:
1. Go into "C:WindowsSoftwareDistributionDownload" and delete everything in that folder.
2. Now, run the command prompt as an administrator. Type in "wuauclt.exe /updatenow".
3. Go to your Control Panel > Windows Update and your Windows 10 should start re-downloading from scratch, hopefully without flaws this time.
If this doesn't work, which it probably will work, you can always head to Microsoft and try downloading from them (again).
There are different ways of saying thanks, but whatever method you choose going here and sending him a message with the gift below is probably the best way.
