WSS Inaccessible after Windows Updates

After a scheduled Windows Update, several WSS sites became inaccessible. The Application Event Log contained events like:Unknown SQL Exception 33002 occured. Additional error information from SQL Server is included below.

Access to module dbo.proc_GetRunnableWorkItems is blocked because the signature is not valid.

I got similar errors when attempting to open any of the tables of the affected content databases in the embedded SQL Server (SSMS to \\.\pipe\MSSQL$MICROSOFT##SSEE\sql\query).
Relatedly, WSS creates copious logs at
C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\LOGS whenever anything goes wrong with one of the WSS services, which fills up the hard drive. This may have had something to do with the failed update.

Anyway, after much googling and trying various solutions, some of which did more harm than good, I followed one suggestion and tried running the following command:

C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN>PSCO
NFIG -cmd upgrade -inplace b2b -wait -force

After some time, the operation completed and all my sites were oparational!
