My experience prior to ISO release as posted elsewhere:
When first available I installed Win 10 on a HD on an older Thinkpad T500 that was running Win 8.1. I had already transferred the 8.1 system to a Samsung SSD. Win 10 on the HD was always really slow. Including yesterday when I updated to 10162. Edge didn't work.
I did a complete system recovery/restore (via Settings) incl. TPM and then later in the process based on my choosing options I was warned I couldn't go back to earlier OS.
Now all is well and no longer slow. Snappy and now happy with this build. It should be really fast when I put Win 10 on SSD. The T500 processor is a T9400 @ 2.53 2.53 Intel Core 2 Duo CPU.
"Get Office" does not get Office but maybe it isn't available yet?????
