Windows 10: How long does restoring take if it is 4 days earlier ago?

I had quite a lot of viruses that somehow got on my pc at 3/14/2021 but it only this day that it appeared

:)

 

restore to 2 days ago

The only way to restore your computer to exactly the way it was 2 days ago is to restore an image backup of your computer that you created 2 days ago.

If you're experiencing a particular problem, and you don't have an image backup from two days ago to restore, perhaps we can help with the problem you are experiencing?

 

restore to 2 days ago

I want to restore computer to 2 days ago.

 

Is it possible to restore Windows 10 to an earlier restore point and back to current?

I have some issues with an application which was running a few days/weeks (not more than 4 weeks) ago.
As I am not able to get it back to run, I would like to restore my system to a point where the software was running (as a test). Thus I maybe find the reason why the application won't run anymore.

My question is, if I do so, am I able to restore the system back (or "forward" in this context) to the current state after restoring to an earlier state? E.g. if I create a restore point right now.

Side note: I'm asking because, I never did restore Windows systems using restore points before.
