Proxy Setting - proxyoverride - proxyenable

Hi.
I have created a fixlet to perform the proxy setting in ie and chrome.
The fixlet works fine, it makes modifications in the registry of windows with the user that is logged.
The incident is when the endpoint user tries to change the proxyoverride setting to add ip or dns addresses.
It also happens when you try to disable the proxy

I would appreciate some help

Here mi fixle

Action 1
regset “[HKEY_USERS{name of key whose ((it = name of current user as lowercase OR it starts with name of current user as lowercase) of (it as string as lowercase) of value “USERNAME” of key “Volatile Environment” of it) of key “HKEY_USERS” of registry}\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings]” “ProxyServer”=“6xx.xx.xx.xx:8080”

Action 2 Proxy-Backup
regset “[HKEY_USERS{name of key whose ((it = name of current user as lowercase OR it starts with name of current user as lowercase) of (it as string as lowercase) of value “USERNAME” of key “Volatile Environment” of it) of key “HKEY_USERS” of registry}\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings]” “ProxyServer”=“xx.xx.xx.xx:8080”

Action 3 ProxyOverride

regset “[HKEY_USERS{name of key whose ((it = name of current user as lowercase OR it starts with name of current user as lowercase) of (it as string as lowercase) of value “USERNAME” of key “Volatile Environment” of it) of key “HKEY_USERS” of registry}\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings]” “ProxyOverride”=“xx.xx.xx.xx;.somesite;;”

Have tried to run it with runas option instead using the relevance substitution?

What you mean by “the endpoint user tries to change the proxyoverride setting to add ip or dns addresses”?

Some users have the need to add to the proxyoverride … ip address or dns of local servers.
Other users like the managers who have laptops, can not disable the proxy.
