We have a few computers wtih Literally hundreds of 1gb update MSI files downloading constantly

We were able to resolve the issue by creating the following registry entries for Acrobat / Acrobat Reader. Once the registries are applied the next update for the App will remove the old Cache files

For Acrobat Reader (32-bit):
Registry path:
HKLM\SOFTWARE\WOW6432Node\Policies\Adobe\Acrobat Reader\DC\FeatureLockdown

Create the following DWORD value:

• Name: PatchCleanFlag

• Value: 1

For Acrobat Reader (64-bit):
Registry path:
HKLM\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockdown

Create the following DWORD value:

• Name: PatchCleanFlag

• Value: 1

For Adobe Acrobat DC Pro:
Registry path:
HKLM\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockdown

Create the following DWORD value:

• Name: PatchCleanFlag

• Value: 1

I have the same issues and just made a post. I removed a total of 8GB of used install files, (I uninstalled Acrobat and that is the amount the folder went down), and 30GB of old unused install files, mostly .msi. How do I know this, all signed as Adobe files. The whole system used around 2.5GB of install files for all the other programs installed on the computer. It appears there is a bug that no old files are being removed after an update. 38GB of used space is ridiclous. This needs to be addressed as the only solution is to manually delete files out of a directory that you should not have to touch. 

Is there an Adobe connection here? It appears to be a Microsoft question without other info.

BTW, I don't have an Installer folder in my C:\Windows folder. Are these from a company such as Dell that might have a bunch of their own utilities installed?
