When using 8, I never had to click on the pop-up UAC approval. It loaded quickly without any confirmations.
I've just installed 220.127.116.11 and the UAC pop-up comes up twice for confirmation to let it load, and then it took 93, 91 and 102 seconds on three trials to get my registration data in order to load. This is on a very fast internet connection.
This is certainly NOT an improvement over 8, and to my view, a major inconvenience.
Are other people experiencing similar concerns?
