Firstly, here is the relevant directions from the release notes of Bitcoin Core 0.21.1:
Note: due to a problem with the certificate authority that provides the code signing certificates for the Windows versions of Bitcoin Core, users on Windows will need to click through an extra prompt to install. It is also expected that there will be a 0.21.1.1 release with an updated certificate when the problem is fixed. If you are planning to upgrade anyway, there’s no reason to delay using 0.21.1 because of this problem.
Entertainingly this will produce shit like this:

Also extra lul points given to this:
If, during that time, 90% of blocks within a 2,016 retarget period signal readiness, taproot will be locked in and this version of Bitcoin Core will begin enforcing the additional consensus rules specified in BIPs 341 and 342 at block 709,632, which is expected in early or mid November.
