WARNING: Intense rant built up over years of raging against boy wonder dickhead programmers who think they're top shit.
Here is a great hint for all those boy wonders who write shit applications that spray their shit applications everywhere - fix your damn applications up.
It pisses me off when I see vendors spray DLL's everywhere, from their own directory to the Windows directory to the user directory and everything in between.
1) Keep your fucking application exe and all the bundled DLL's in your application director - leave the fucking Windows directory alone. It is not for YOU to place YOUR shit into. It is for Windows and Windows only.
2) Don't write shit to your application directory; if it is a universal setting then you should ask the user for permission and write it to the global registry. Is it a user related setting then save it to the user profile. No if's, no buts.
3) Don't use undocumented API's and hacks. You aren't cool, you aren't hip, it doesn't make you gods gift to the world because you're using private API calls never intended by Microsoft to be used outside their operating system development teams. Its private for a reason - private meaning it is not for you to fucking use. Hack away at Microsoft's private api's and I'll hack away at your privates.
Do the fucking job properly the first fucking time and stop turning a clean and pristine Windows installation ito a fucking dogs breakfast because you think you're top shit when clearly you're not.
