every time I try to install an update on my son's computer I get this
"setup could not verify the integrity of file update.inf. make sure the
cryptographic service is running on this computer"
Crypto is running so i'm assuming I have to repair/reinstall this file
but I have no idea how!!

Help please!!

What Windows version, edition and Service Pack level?
(For instance, I'm using Windows XP Professional edition, SP3.)

Except for KB973346, Is the computer fully patched at Windows Update?

To check Services:
Click Start, click Run, type or paste next line and press Enter:
%SystemRoot%\system32\services.msc /s

Cryptographic Services should show:
Status: Started
Startup Type: Automatic
Logon On As: Local System

Cryptographic Services
Provides three management services: Catalog Database Service, which confirms
the signatures of Windows files; Protected Root Service, which adds and
removes Trusted Root Certification Authority certificates from this
computer; and Key Service, which helps enroll this computer for
certificates. If this service is stopped, these management services will not
function properly. If this service is disabled, any services that explicitly
depend on it will fail to start.

That service depends on Remote Procedure Call (RPC)
It also should show Started, Automatic and Local System.

The problem you are seeing could be the result of malware. You need to make
