Windows Upgrade Help and more

So basically, That error code can be a real headache, especially when you know your PC should be compatible. A common fix for that specific one is to temporarily disconnect any non-essential USB devices (like printers, external drives, or hubs) before starting the upgrade again—sometimes they interfere. Let me know if that doesn't do the trick and we can try a few other steps together.

Same here. You could also try creating a Windows 11 installation USB and using the "Upgrade this PC" option from within Windows 10, which sometimes bypasses issues with the built-in updater.

Having a lot of trouble upgrading my Windows 10 PC to Windows 11. The setup gets partway through, then fails and rolls back. The error code I keep getting is 0xC1900101 - 0x30018. My machine meets all the requirements, and I’ve run the update troubleshooter. Has anyone found a reliable fix for this? It’s pretty frustrating after the third attempt.

+1 Yeah, that's a solid approach. One extra tip: if you have any non-essential USB devices or external drives plugged in, unplug them before starting the upgrade—sometimes they can interfere.

Can confirm. You could also try creating a fresh Windows 11 installation USB and using the "Upgrade this PC now" option from within Windows 10, as it sometimes bypasses update cache issues. Hope that helps.

Worked perfectly, thank you!

Agreed, that error can be stubborn. Sometimes temporarily disconnecting any non-essential USB devices, like external drives or printers, before starting the upgrade can help it go through. Hope that helps.

Same here. Also, have you checked if there's a specific driver, maybe for your graphics card or chipset, that needs a manual update from the manufacturer's website?

+1 Yeah, that driver tip is spot on. Also, try temporarily disconnecting any non-essential USB devices before starting the upgrade—sometimes peripherals can interfere.

Yeah, I had the same problem. For me, it was a specific audio driver that Windows Update kept trying to install; I had to manually update it from the manufacturer's site first.
