Windows 10: Safe to upgrade to Windows 10?

I tried to upgrade my laptop to windows 10 last March, during the upgrade it got stuck at a certain percentage at which it crashed. I had to go to a computer-store to get it fixed, they've put Windows 8.1 back on.

Is it safe to upgrade now? Especially since Windows 10 is only free until the 29th of July. Sorry if a similar issue has been posted before, but I could not find it. My laptop specs are:

Toshiba Sattelite S50-B-12R
i7-4510U
AMD Radeon R7 M260
16GB RAM
Regular 1TB Hard drive

Many thanks in advance!

Rotation Lock button is gone from Action Center

By the way, Acer seems not doing good on their products. This is my second one from Acer, I have a Predator 8 tablet and the same it has problem that need to be brought back to manufacture repair within one year. Lucky that was still warranty. To me that
it is 100% chance product will fail. I would never touch any Acer product again!!!

 

Rotation Lock button is gone from Action Center

I don't when it starts to happen since I am using my tab like a desktop most of the time. Couple weeks ago I started finding my Acer tab Switch SA5-271 cannot rotate the screen at all.

Trying to enable it from Action Center but the button is gone.

I also tried to look for it in the Display setting, the switch button is also gone under the Landscape Orientation.

I looked for it from "Notifications & actions" setting to try to add the button back to Action Center, the Rotation On/Off switch is not available.

So I started to find the latest update from Acer and Microsoft, it is now with everything up to date but it is still no helping. No auto screen rotation at all.

Does any have the same issue and know how to solve it?

Thanks,

Raymond

 

download the windows 10 ISO Tech Bench
and then run the setup.exe file within your current OS to upgrade manually

 

Please post the error you got when the installation crashed and someone may be able to advise. Some installation problems are nothing to do with Windows 10 which sis now reasonably stable. I had a failed Windows 10 installation due to a problem with on of my hidden system partitions in Windows 8.1.
