Just a PSA and sorry if posted before - as the title says. Suggest not installig it until it is fixed.

If you have, luckily emough there was a recent 11 update which does a system backup. So you can reboot to start mode and choose the last system restore point. Sorry if you don't and have poor system backup discpline. I really do too!

Edit: Wanted to add that after I let Intel do the upgrade, it worked OK for a while but then disconnected me from the AP and wouldn't let me reconnect. Reboot got me back in.

Then me and the fellas were up to our guts in bugs, was preparing to drop some filthy strats on ‘em and kabooey! No network.

Reboot then didn't fix. System restore did.
