Why Can’t I Sign In After Reinstalling Windows?

I had a similar problem after I reinstalled Windows! What worked for me was waiting an hour and then trying again. When I finally got back in, I checked my internet settings and made sure everything was connected properly. If you're okay with trying again later, that could be the easiest route. But if you're feeling impatient, definitely give the local account trick a shot—it worked wonders for me!

Honestly, if the error is saying that something went wrong, it could just be a temporary server issue. If you just wait a bit, everything might be fine when you try again.

But, if you need to get this sorted out right now, creating a local account is the way to go. Disconnect your internet and follow the prompts to finish setup. Also, be sure to restart your computer; sometimes that’s all it takes to clear up weird sign-in issues after an installation.

It sounds like you’re running into a snag with Microsoft's servers or possibly your internet connection. A good first step is to wait a little while and try signing in again. Sometimes these issues resolve themselves after a bit. In the meantime, check your internet connection and maybe restart your computer—these simple fixes can often clear up any hiccups.

If you’d rather not wait, there are ways to create a local account. One method is to disconnect from the internet during setup to force a limited setup option. When you get to the network connection screen, unplug your Ethernet cable or disconnect from Wi-Fi, then you should see an option to continue without internet.

Alternatively, if you open the Command Prompt by pressing Shift + F10 on the sign-in screen and type 'OOBE\BYPASSNRO', it should reboot and allow you to set up a local account. If all else fails, some folks have had luck using a fake email (like [email protected]) to trick the system into letting them create an offline account. Good luck!
