Wix\heat.exe strange output

Question

I have a directory with one file there: Iesi.Collections.dll.

When I run the following command:

heat.exe dir D:\MyDir -cg References -srd -o D:\Product.wxs -nologo -gg -g1 -dr INSTALLFOLDER

I got really strange output. May be it is strange only for me so please explain it to me. Why I get these registry values? I get the same result for any third party dll like MassTransit or RabbitMQ.

Expected output:

<?xml version="1.0" encoding="utf-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
    <Fragment>
        <DirectoryRef Id="INSTALLFOLDER" />

            </Component>

Current output:

Answer 1

You should supply heat.exe with -sreg (suppress registry harvesting) and -scom (suppress COM elements harvesting) command line switches. See heat.exe -? for more options.
