Vista no longer able to access CD or DVD drive

I suddenly had a weird problem with Vista today, that took some valuable time (more sensibly otherwise spent) to fix — here is a quick note if you face something similar. If a CD extracting program (e.g. CDex or similar) starts to complain about a missing ‘wnaspi32.dll’, check whether you are able to see the DVD/CD station in My Computer at all. If not, then you might have a corrupted Windows Registry (yikes!) But the fix to that is actually pretty simple: I followed these Microsoft instructions (the manual version) that relate to Windows XP, but the “delete UpperFilters entry” trick seemed to fix also my Vista Home Premium 32bit just fine.
