Hi,

i saw today the folder c:\windows\installer take 160GB space disk.
This server has AD roles and an SQL express for sage application install on it, that s it.
All updates has been install.

I don't understand why this folder take so much place on this server ?
Any one has an answer ? is it a bug ?

Regards

    Hi,

    When applications are installed and updated on the Windows Operating System a hidden directory "C:\Windows\Installer" is used to store the installer (.msi) files and the patch (.msp) files.

    Hi,

    Thank you for your help,
    this is a production server and for now there is now need to perform cleanup.
    But for information : Disque cleanup will free 5Gb ( 4.65G windows updates)
    and their is 12G on WINSXS.

    The day i posted this question, their was than 2100 msi files on the installer folder and they make almost all 80,5mo, this is not normal !
    No install was perform and today, three day after 5G was lost again and their is 66 new msi file. Something goes wrong !
    i need to find a fix before there won't be more free space

    Regards
