The shlwapi:istream tests and Microsoft Security Essentials

[Paul Vriens]

Hi,

I was wondering why I (out of all those boxes) had several failures for 
these tests on some of my XP and Vista boxes.

Turns out that you get these failures when MSE is active. I just ran the 
tests on a clean XP-SP3 box (up-to-date) and no failures. Installing MSE 
(and downloading the latest signatures) is enough to show a multitude of 
test failures. Turning 'real time monitoring' off or excluding the test 
executable makes the tests succeed again.

Most of the failures are of the E_ACCESSDENIED nature btw.

Does this make sense?

If the test failures are valid, should I change the tests to cope with this?
