I'm working with an old weary Windows Vista, I've been using it since four or five years ago, installing many different stuff and uninstalling others. Only recently I tried to tidy up a little bit my system, and I discovered this windows\installer folder, mysterious and lethal and also huge. I searched around to find if there is anything I can do to somehow cut off a bit of that, and best thing I found was Microsoft tools, different versions and names, so I used this Fix it troubleshooter, after Microsoft Installer Cleanup Utility (
msicuu) crashed my computer twice, and started to remove almost anything I thought I should, and along with that, I removed tons of programs using Windows's plain old add/remove program utility. So I thought after all this I would find the installer folder a bit shrunk, but it is still exactly like the first day.
Now I'm totally disappointed and confused, I thought the contents of that folder had something to do with installing and uninstalling my programs, but it looks it's not. So I would like to know what exactly is in there and which parts I can safely delete, and maybe some hint on how to do that would be extra helpful.
P.S: I sure have already checked Is it safe to delete from C:\Windows\Installer?, It only tells me it is evil, stay awy from it; and I found How to safely delete stuff from %SystemDrive%\Windows\Installer? rather irrelevent.
