    Deleting of Windows Installer Cache (C:\Windows\Installer\) Files


    Posted: 31 Jan 2012
    Windows Installer Cache, the c:\windows\installer folder by default, is used to store important files for applications installed using the MSI Windows Installer technology and should not be deleted manually.

    I've never messed with that folder, but after reading the article, it makes me wonder about the validity of using Acronis's Universal Recovery procedure to use an image of one machine on another. I've never done that either, but that was the primary reason that I bought the latest version of True Image.

    I found that folder and it has lots of things in it and I will leave it alone. Could something messing with this folder also stop Windows Updates?
    Thanks for the information.

    I once removed that folder ages ago (xp days) just to save some space but I knew it was important years later. Thanks for the information!

    You must untick Hide protected operating system files (Recommended) to see it

    Hmm.. Usually if I see folders with lots of files I delete it immediately to save space. Tried deleting system32 once but it did not finish saying it's in use or something. So when I turned off my computer, Windows would not start anymore.

    Man that error messed things up!

    On a serious note, thank you for the information!

    If people want to save space, turn off the Windows Update service, then go to the Windows folder and delete the contents and folders under the SoftwareDistribution folder, then turn Windows update back on. You can recover up to a couple GB of space that way. The only nuisance is that if you have hidden any updates, you will need to rehide them since it resets Windows update to its default.

    I find my safest way is through disk cleanup and tick all offered file. And of course Office installation cache.
