    what is aecache.dll doing in the root of my system drive?


    What is aecache.dll doing in the root of my system drive?

    The details tab says it is from microsoft. But the location is very unusual.

    My searches have produced a long list of hits but no concrete info.

    Does anyone truly know what this program is and why it is where it is?

    aecache.dll is the "AECache Sysprep Plugin", so tied in with Sysprep. It is located on my computer in System32, which, according to what I found is the correct location. From TechNet: How Sysprep Works

    Note: aecache.exe is not related, is located in startup and is detected as Trojan.Win32.Obfuscated.gp by F-secure.

    Corrine,
    Thanks for the reply. The only thing that bothers me is I don't remember having installed anything related to sysprep except for installing the WAIK.

    Did that install result in aecache.dll being there? I did rename it to aecache.lld (had to give ownership to administrators first as before I think it was the built-in administrator that had permission by not the Administrator group.)

    The aecache.dll in System32 has a Created date of July 13, 2009, which is also the same as the last modified and last accessed date. I don't recall if that was when I installed Windows 7 on that partition but guess it probably is since there are numerous dll's with the same modified date.

    So, process of elimination, the second copy at the root of your system drive must be from the installation of the installation kit.

    Don't really know. It's just a possibility. That's not the only software that has been installed and I just noticed its presence by accident when I was doing some testing.
