Task to increase IE cache vis registry

I am having some trouble setting up a registry task to increase our IE cache to 250 mb for all customers. My basic script is

action uses wow64 redirection false

delete __appendfile

delete wizardedit.reg

appendfile Windows Registry Editor Version 5.00

appendfile

http://HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\Cache\Content

appendfile “CacheLimit”=dword:003EBE8

appendfile

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Cache\Content

appendfile “CacheLimit”=dword:003EBE8

move __appendfile wizardedit.reg

waithidden regedit /s “wizardedit.reg”

It runs as successful but does not make the change on the desktop. Any help getting this to work for me is appreciated. Writing scripts is not yet my strong point as I am learning BigFix.

Cheers, Carroll.

The agent runs as system and therefore does not see the HKEY_Current_user branch. You will have to run it as the currently logged on user.

Changing the HKCU registry

Here is how to change the registry for the logged on user:

appendfile REGEDIT4

appendfile

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main

appendfile “Start Page”=“http://www.google.com/”

copy __appendfile temp.reg

prefetch RunAsCurrentUser.exe sha1:a72371f4e968da7ead24f0f4e68c14b234ac94f6 size:184320 http://software.bigfix.com/download/bes … er-2.0.exe

utility __Download\RunAsCurrentUser.exe

waithidden __Download\RunAsCurrentUser.exe regedit /s temp.reg

Notes:

Only works if a user is logged on.
If multiple users are logged on, the user logged in at the computer’s console will have their registry updated.

Hello Carroll,

I’m not quite sure what the question is. Are you saying it worked on your machine?

What relevance are you using to target machines? It appears that it did not run at all on your asset machine because it says it was not relevant? Is that correct?

Hello Carroll,

Here are a few suggestions.

It looks like it’s failing because runascurrentuser.exe is not being downloaded. Copy and paste the link in a browser to make sure it is a good link.
Make sure you check that the relevance evaluates to true using the debugger on your machine.

It looks like in your relevance you are checking for the setting in HK_USERS

of key "HKEY_USERS\S-1-5-18\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\Cache\Content " of native registry

and in your action you are trying to change the logged on user:

http://HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\Cache\Content

This looks like another situation where my technique of for examining the “Current_User” portion of the registry would help. S-1-5-18 is the well-known SID for the SYSTEM account. Take a look at the code in this thread:

http://forum.bigfix.com/viewtopic.php?id=3757

I know I sound like a broken record bringing this up in thread after thread, but I think it is better than downloading an app to run as another user. It also allows you to check to see if the change is needed with relevance, which is what would really help in this particular situation.

Here is the code that worked for me. Handy to increase cache for a web based app we are using. Bumps it up from 65 to 250 mb.
