I am early testing windows 10. Overall I am liking the OS but it has it quirks and issues. My biggest issue involved the Juniper Pulse client no longer functioning.
I recently upgraded to release 100130 and found the pulse client not working and the OS required activation.
The product key had changed and the new one would not take. The error basically said the wrong product key is in play?
I tried many things and nothing worked. Then, I remembered I was testing the Enterprise version.
A quick check of the site and sure enough there was a different product key. I used it and the OS activated.
The pulse client decided to be a pain again. It would take the token and then sit forever with a message about securing the tunnel.
I installed the latest build of but the problem remained. I removed and installed the client and this time it was able to connect!
