Win 10 20H2 upgrade

[Larry R.]

I have a Lenovo Ideapad 100 (with an I5) that stalls @ 49% of Win 10 20H2 upgrade. I've even re-installed Win 10, with the same problem; I've tried the MS recommended "fixes" with no luck. Any ideas?

When it stalled, how long did you wait before giving up? Some windows updates take hours, seeming to be doing nothing. I guess it's a feature.

Hi,
I let the 20H2 "update" go (on one attempt) for over 10 hours (overnight plus a couple of hours) ; ALWAYS stalled @ 49%. The first 48% went in less than a half hour, (and slowly showed progress.)

Have you tried to update it using the repair upgrade install ISO route from Microsoft instead of installing the update via the Windows Update service?

You should also be able to use the windows 10 update assistant, though the issue could possibly be a hardware problem, like with the drive.

That was the number one issue I used to see when the big update was failing. Number 2 was not enough storage space.

I would start by running disk cleanup including system files. And run crystaldiskinfo to check drive health. Then go from there.

Thanks, Sorry I was away for a while... (personal/family business) A couple of questions/comments:

1. Wouldn't an ISO install "remove" any special software/drivers specific to the Lenovo Laptop?

2. The hard drive has more than 500 GB "free," so THAT (lack of space) shouldn't be an issue. (I don't use the machine for games, or "streaming.") It also has 8 GB of memory.
3. All the other "updates" for Win 10 have gone without a hitch; it's the 20H2 installation that "stalls" @ 49% According to Lenovo, the model laptop IS supposed to be compatible with 20H2.
4. I'll try again, using the Win 10 Update Assistant, but the machine gets the updates through Settings> Update, and (at least seems to) upload the 20H2, it's during the installation of the update that it stops. (Probably won't happen, though, until a day or two after Christmas.)
4. The "firmware/BIOS was upgraded to the latest available.

Yes, which (at least IMO) is a good thing.

Personally, I would wipe the drive (assuming you've backed up your personal data first and you know how to install any non-Windows software you need), do a clean install of Win10 (1803 being the earliest version I'd consider using), connect it to the Internet, do a Windows Update check, it'll install any drivers it feels are necessary, then see what's still in 'other devices' in Device Manager after the first wave of device updates have installed and if need be, install only the drivers you need to from the Lenovo site. If in doubt on that last point, ask for help.

OEM supplied software is generally good for screwing up Windows and slowing it down, not a lot else. Occasionally you'll get say a better video driver from your manufacturer, but that wouldn't be my default assumption; often the laptop manufacturer's drivers are older/inferior to say Microsoft-supplied drivers or the actual component manufacturer's device drivers.
