Q:

Why this question was downvoted and closed?

Drivers for recent (64-bit) version of Windows must be signed before
  they'll load. Which certificate issuers can supply a certificate
  suitable for this?

http://www.stackoverflow.com/questions/6689758/what-certificate-do-i-need-for-windows-driver-signing
What it misses to be "well written"?

A:

Currently that question is open and positively scored. But take a look at the question's revision history. That question used to be

Where to buy certificate for driver signing?
What are possible choices, which ones are cheaper?

And that is simply off-topic. That caused it to be closed and more than likely explains at least some of the downvotes it received.
