I accidentally clicked an icon in my tray, that is usually for just restarting once an update installed, however this time it consented to 20H2 installing (merely with a single click - I thought it would open the Windows Update Settings screen to ask me to schedule a reboot time, rather than agree to this) because 1909, which I am on, will not be supported. I tried deleting the update directory (C:\WINDOWS\SoftwareDistribution\Download) and it just redownloaded 20H2. I do not want this version as it is still experimental and I have seen on Youtube videos that it is responsible for high CPU usage for some people not to mention [1] (if I could update to 2004 which is known to be more stable, I would do that but it is not available). I know it's possible to revert the update within 10 days, but I'd like to avoid the risk and time involved with that as well as the possibility that it will just restart the cycle of downloading and installing 20H2 once I do that.
