About to Update to Windows 10 version 20H2, How Essential Is It? + WT

Hey all.

It's the regular tech noobie. So about 2-3 weeks ago I was cleaning up storage from Steam games that I don't play, including War Thunder, to make up some spaces for other stuffs. After the cleanup, Windows updater downloaded the 20H2, but it's not yet installed in the regular mandatory "Update and Shutdown". It instead has a separate tab of "Update and Restart", while the "Shutdown" button does not seem to initiate it.

So I let it be. I read some forums that the 20H2 has some issues that makes me hesitant to use it. Some that I found are
1. Legacy Edge's end of support. I only use Edge for opening PDFs or Battery Health Check, so how different is the new Edge?
2. I read that a Control Panel feature is removed.
3. Microsoft Photo Viewer and Start Button not seen.
4. Less-cluttered "Start" options, that I personally kinda dislike. The previews pictures of the update I see makes the "Photo" preview tab on the Start menu disappear. I wonder if that can be reapplied again?

How essential is it to update to Windows 10 version 20H2? If I somehow get myself disappointed in it, is it possible to rollback to the version I'm using now when writing this post, which is Windows 10 version 1909 (OS Build 18363.1440). If so, how do I do it?

I think I'll add another question here too, in case it's somehow related to it.
So when I was uninstalling War Thunder from Steam, I uninstall the launcher from the Steam, and then I deleted the "War Thunder" folder from the "Steamapps" -> "Common" folder. The storage capacity was at 24 GB, and then after I deleted the folder, it gets to 56 GB. Around the same time when I was uninstalling games, Windows updater downloaded the 20H2.
After I was done, I forgot that I either let the lappy on "Sleep" or "Shutdown". The next time I open it, I think it was the next day, I checked the storage, and I'm surprised that the storage is around 24-27 GB. I rechecked the folders, and even checked the "Users" -> "Appdata" -> "Roaming", and didn't find any trace of it. I also made sure to empty the Recycle Bin.
Some questions came to mind.
1. Is this related to 20H2?
2. How do I solve this? I checked "Disk Cleanup" and it didn't show any clutter of files except the ones that I know I'm working on.

I look forward to your answers.

Thank you.

P.S: My system spec is ASUS ROG GA502D with 8GB RAM and 500 GB SSD.

Hi,

Not essential no, for the moment.

Rolling back is simply, Start > Settings > Update & security > Recovery > under Go back to my previous version of Windows 10, click Get started.

Are you saying you have gained or lost GB?

If gained, is it possible you have deleted a Win.old file, they could be large, up to 20gb?

If lost, that's a fair old junk, I would want to know how/where.

Did you misread the GB space?

If I'm understanding correctly 20H2 is just a very large update but would still only require at most 10gb of free space dependent on win build it's updating.

As a raw 20H2 OS, space requirement would be larger.

Like dalchina I to recently installed 20H2, admittedly I'm not as adventurist with Windows as some and make do with what's given me on my plate for the most part.

Pro's Cons, I think there is an improvement with boot times but if there is it's a blink of the eye thing, I don't use Edge, never have.

I have noticed unresponsiveness to mouse clicks, so if I click on certain app' icons on the desktop they don't open, having to click/double click again.

I'm happy enough with 20H2, I think most will be.

20H2 to my mind appears more orderly but that may not suit everyone

- - - Updated - - -

When installing 20H2 does it create a win.old folder as I don't have one in my C, ( OS ), drive?

I do have a 20H2 folder named 20H2 updater but it's tiny, 21.5mb?

Upgrading to 20H2 created Windows.old on mine - it was hidden - I found I had to make it visible. Odd, 'cos it's now permanently visible.

Thanks, how did you make it visible?
