Solved: Long delay before context menu shows up

[Robert Kochem]

Hi newsgroup.

The last months I noticed that opening the context menu of shortcuts took
sometimes very long (5-10 seconds). I found out fast that this happens only
on shortcuts that are broken (the executable the shortcut links to does not
exist anymore) - but it only happens on one PC therefore a software (or to
be detailed a shell extension) must have been the cause.

Investigating a problematic shell extension isn't simple but finally I
found today the cause:
Using Sysinternals ProcessMonitor i traced the long delay back to a shell
extension named "CmdLineExt.dll" (located in the system32 folder). The DLL
description named it as "SecuROM context menu for Explorer." from "Sony..."
WTF - why needs a copy protection needs a shell extension?

After deactivating the shell extension via "regsvr32 /U CmdLineExt.dll" the
delay was gone.

Conclusion: Another unnecessary and bogus software brought you by Sony
(also known as the "rootkit publisher"). I can only suggest everybody to
deactivating this useless shell extension.
