not scanning all profiles for issues in appdata, and not removing uninstall info from the reg.
example, all the mindspark tool bars.... it will remove the BHO and the folder, but not any of the reg info from uninstaller, so it "looks" like its still installed
i had to write a script to go back and clean up..
reg query HKLM\software\classes\installer\products /f "Mindspark" /s | find "HKEY_LOCAL_MACHINE" >> %TEMP%\X.txt 2>NUL
reg query HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall /f "Mindspark" /s | find "HKEY_LOCAL_MACHINE" >> %TEMP%\X.txt 2>NUL
reg query HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall /f "Mindspark" /s | find "HKEY_LOCAL_MACHINE" >> %TEMP%\X.txt 2>NUL
reg query HKEY_CLASSES_ROOT\Installer\Products /f "Mindspark" /s | find "HKEY_LOCAL_MACHINE" >> %TEMP%\X.txt 2>NUL
reg query HKLM\SOFTWARE\Classes\Installer\Features /f "Mindspark" /s | find "HKEY_LOCAL_MACHINE" >> %TEMP%\X.txt 2>NUL
for /f "tokens=* delims= " %%a in (%TEMP%\X.txt) do reg delete "%%a" /f
