I have the same issue after a bios update. No internet access and Microsoft have not sent out the verify code to input. I've borrowed a laptop to get online and checked my online email and no email from Microsoft. This is a new pc with new bios and will have regular updates. I cannot afford this type of hassle. Microsofts answer when speaking to TECH, CLEAN INSTALL.
It's taken me six weeks to install software to this point, I don't have the time to waste to start again. It's all this TPM rubbish.
The only answer if I get ack in is to have no pin and or no password! Not impressed and reinstall appears to be the only answer Microsoft have to any issue.
