Non admin accounts cannot log in after streaming is installed.
Here is the scenario:
Windows 7 SP1
Streaming agent 7.5
Symantec Endpoint Protection 12.1
On a freshly imaged computer if we install the SEP agent prior to installing the Streaming agent only admin accounts can log in to the computer. If a non admin account attempts to log in they only get a black screen and I can open the task manager and it indicates that explorer.exe is at 100% CPU utilization.
If SEP is installed after the streaming agent then users have the ability to log in with no issues.
