Windows 7: Windows OS disk always full - /Installer and /winsxs culprits

Windows OS disk always full - /Installer and /winsxs culprits


My SSD OS drive always seems to be full and if not it's always increasing in size very fast even though the only things I install on it are drivers and firmware.

Is there something I can delete to remedy this?

What have you done in the way of disk maintenance?

Have you run Disk Cleanup including the option for system files?

Have you turned off hibernation if you don't use it?

Have you checked to see how much space is devoted to System Restore?

Do you know the size of your page file?

Have you uninstalled applications you haven't used in a year or more?

For your comparison:

My Windows directory is 26.5 GB; yours is 45.1

My Windows/installer directory is 5.8 GB; yours is 20.1

My Windows/software distribution directory is 1.3 GB; yours is 2.3

Your other directories are fairly close to mine in size.

I have a 5 year old Windows 7 installation that currently occupies 40.5 GB.

You apparently have a 64 GB SSD. That's smaller than most people, so you have to take some care about holding down occupied space or else spend say 70 to 100 US dollars for a considerably larger SSD.

Looks like you have a lot of msi installers. You could check and see if there are any duplicates.

Theoretically you could dump all of them, but it would then be tricky to uninstall/repair the programs they relate to.

Winsxs suddenly taking up 80% of disk space
Just today I got a notice my SSD was getting too big. Taking a look further, it seems the culprit is winsxs file. I've had this computer for 4 years and have never seen this. It is 35gb in size, that folder alone. What is going on?

Large installer and winsxs folders
My windows/installer and windows/winsxs folders are 12.7gb and 12.1gb respectively. In fact, my windows folder takes up 40gb of my 68gb of usable space. I've done some reading about this and people seem to say not to clear these out and instead to just uninstall software. However, when going...

WinSXS folder full of compromised files
I've been fixing my friend's laptop (replacing the fan). The user experience is really slow so I've also been doing the kind of maintenance I'd do for my mum/grandmother. His AV and various other stuff has been out of date for a long time so I installed Avast! and it found a whole load of...

Winsxs file already consumes half of my disk space...
I recently replaced a 60GB SSD because my winsxs file was using over 25GB and I was down to about 8GB of usable space. I went out and bought an 80GB SSD and after my install it was already half full before I put any application on it. The winsxs file is already at 11GB and I really do not want to...
