Windows Interesting little tidbit from the Reddit AMA session with Microsoft's Surface team. One Redditor wondered just how much disk space Windows RT takes up - in other words, if you buy the 32GB Surface RT tablet, how much space is left for your stuff? It turns out that while Windows 8 RT is considerably smaller than its Windows 7 x86 predecessor, it's still huge by mobile standards.

It is also known to grows in size over time.
This can be because of installation files being left over even if the application is uninstalled.


Interesting. Under what circumstances are installers left over after applications are uninstalled?

I've noticed that a lot of installers extract to a temporary directory, and then forget to delete it when the MSI finishes running. But this has nothing to do with uninstall -- they eat up the disk space even if you never uninstall the app.

The \Windows\Installer directory should clean up after itself. It's those pesky temporary directories that bootstrappers extract into that tend to hang around.

Sometimes MSI will leave files to "aid uninstallation". IIRC, Borland did this with Delphi 2005. It was very annoying. Something to do with a catalogue of files installed or similar. I've also encountered at least one installer that did the same so that features could be "installed on the fly" without the original medial being present. Some installers are just crap though and son't clean up properly.

Not just sometimes. Every MSI installer (yes, Microsoft Installer Installer...) you run is copied and stored inside your Windows folder with a cryptic name slapped on it, because the MSI file is also the uninstaller for a program. You run into problems when, even after uninstalling a program, that file doesn't disappear.

As an aside, a problem I have to deal with at work on a semi-frequent basis occurs when some clever fool finds and decides to clean up this dozens-of-gigabytes folder of installers. Pretty much the only programs that seem to have a problem with that are iTunes and Quicktime, which apparently can't update without the old installer there to remove the old program. The solution is to use a Microsoft tool that removes all of the registry entries pertaining to iTunes and Quicktime, so Windows just no longer knows it's installed, and the new version's installer can run unimpeded.
