The latest feature update for win 10 21H! is available via Win Updates when you select 'check for updates'

It's a very, very, quick download and install. No issues so far.

Took 55 minutes from start to finish for me using the Windows 10 May 2021 Update utility.

-------------------------------

So far it doesn't look like it broke anything obvious but it did cause some errors that I discovered using command line tools.

These by now should be obvious to run after a major update!

Repair Disk Errors:
1. In an admin Command Prompt or PowerShell run:

ChkDsk /F C:

Or whatever the Windows OS drive is. For me it found and corrected Volume Bitmap errors immediately after updating.

2. Restart the PC after running that command line repair tool.

 

Repair Possible Corruption:
1. In an admin Command Prompt or PowerShell run:

DISM.exe /Online /Cleanup-image /Restorehealth

2. In an admin Command Prompt or PowerShell run:

SFC /scannow

v20H2 caused corruption for me and it was the same situation with the current v21H1 which SFC reported that it repaired.

3. Restart the PC after running those two command line repair tools.

Why did you use the Update utility you linked to instead of Windows Update (just wondering)

That is for the 10th May update plus anything after it.

The 21H1 update itself is just a couple of minutes long and turns on features downloaded in previous updates.

Just done it through 'Check for Updates'

Took 5 mins (download speeds of below 5Mbps) from clicking 'Download and install' to 'Restart'.
3 mins for the restart to get back to the desktop.
Then another 2-1/2 mins for Task Manager to settle down after the restart.

So 10-1/2 minutes overall for the upgrade from 20H2 to 21H1.

For anyone interested data usage shows as 4MB for the download.

Worried about 'Tracking Files'? Worried about why some files come back after cleaning? See this link:

Since 2019 Automatic Updates has never offered me anymore of the upgrades to the newest OS version (could be something to do with the lack of validation from Acer, or whatever else the cause is why they aren't pushed to my laptop). It would've likely never been offered to me just like v20H2 never was just like what came before it v1909 and v1903 all had to be manually invoked to get those upgrades.

Know what you mean, I've got a friends laptop here and that won't go above 1909 using 'Check for Updates'.

I tried using the Update Assistant on it yesterday, but it wasn't having any of going from 1909 to 21H1.
(It looked like it was, and took an couple of hours to finally decide that it wasn't going to play nice).
I'll probably have do do it by creating an installation USB.

My thinking is (without actually trying it) is there's something with the OEM installation that is perhaps causing it, and a fresh install could possibly fix it - that's a big guess. One of these days I might actually get around to doing a clean install, but not today.
