How to Update to Windows 10 21H1 May 2021

Hello guys, I just reset my pc, can you guys suggest me on how to update all my outdated programs.

hey i am not good with computers and i was doing a scan with windows secuirty and it says that it found a trojan vsb mutuodo.a and that it was removed, but is there anything more i have to do, and it says there is one affected item, do i have to do anything about than, or is my computer all good now, i am really worried

I'm using very old version of Windows 10. Whenever I try to update major update I wait couple hours but at the end it says rolling back changes and no update. I thought because I don't have enough space in C:\ but I've used external 1 TB HDD and still no luck. I don't know what to do. I read in some sites what's wrong but I had no luck. I gave up. :P What matters, it's impossible to install other version of Windows (7 or 8) because no drivers, only for Windows 10 64bit and that's bad enough . :P

I have had the update for a week, but when I try and do it, it gets to 98% and then it stops and undid the changes, every time I try and do it

Shalom Tim.
Peace and Grace be to you.
Thank you again for all the tips. Much appreciated.
God bless. Amen.

So why is this update so important, too many Windows updates in the last 2 years.

Cool
