Windows 10 Prevent File being deleted in Internet Explorer's temp files

[Jay Ocampo]

Hello,


I have a file on an employee's computer that builds in Internet Explorer's temp files when using an online service. I need that file to not be deleted at random. The file in question is RinconClient[1].xap, pictured below in the Event Viewer, with file auditing.




I have narrowed it down to either dllhost.exe or taskhostw.exe deleting the file. We have antivirus software which has not detected anything malicious in regards to the RinconClient[1].xap file.


In Internet Explorer, I have
Empty Temporary Internet Files folder when browser is closed = Unchecked

Delete Browsing History no exit = Unchecked

Check for Newer versions of stored pages = Never

Allow website caches and databases = Checked


In Task Scheduler

CleanupTemporaryState = Disabled

SilentCleanup = Disabled


I have messed with permissions to the C:\Users\%username%\AppData\Local\Microsoft\Windows\INetCache\Low\IE folders and subfolders.


I have tried a script which copies the file to each folder and subfolder in

C:\Users\%username%\AppData\Local\Microsoft\Windows\INetCache\Low\IE

Did not resolve the issue.


OS Name: Microsoft Windows 10 Pro
OS Version: 10.0.17134 N/A Build 17134



Is there a way to make sure IE's temp files do not get cleared out or to protect that file?


Edit:

I have done these same changes on my machine, and the file is still there and the issue does not occur.

I have made the same changes to the user's machine to no avail.
