I've manually installed 9126, however Windows update has just installed a far older driver. What's going on?

 

It seems the most recent Intel drivers for display, wifi and bluetooth (installed from their tool) have been overwritten and older ones put in their place by Windows update.

 

Do I have to block windows update to stop s**t like this happening?

Thats a good point.

I was waiting to write a review about this issue you mentioned regarding the windows updates.

I have experienced this many times and now whenever windows update does something this flickering starts again. Besides, yes it always suggests much older driver versions.

After that i reinstall the latest driver of graphics and issue is getting solved again.

 

I am planning to shut off automatic updates on windows. I can update manually time to time in every few months.

The issue my laptop had was flickering and some sort of shake or shiver of the Taskbar where the clock etc was replicated downwards. Very slightly but flickering. 

Not sure if you can see it on the screenshot I took from the video, cause its not the best quality. The issue wasn't that bad when I shot the video either. 

But actually I sent the laptop back today. I had till the 18th to send it back and trade it for a different one. 

Hopefully the new one doesn't have the same issue... 

Otherwise I want my money back and I'm getting a different brand.

I think they will replace some parts.

Yeah, this issue is probably hardware related... 

Keeping fingers crossed the new one is problem free!

dont worry it will,

Actualy i would like to be sure about our issue also was about hardware. so they could replace whatever it needs and it would be solved without headache.

Instead, we have spent hours and hours for testing and many ways we tried just to understand whats going on you know...

 

Well, some of my friends bought some brand new devices from that "customer service wonder" company and some other companies. They also  having some issues about external display issues, heating etc..

 

Why is it so hard to find a machine without any issues nowadays?

Good luck to us all as customers.

A laptop or pc without any issues is non existent I think. But seeing how much money ppl are paying for these devices you should be able to expect it working properly. 

Hopefully for you guys, these drivers will keep the issue fixed! 

 

Good luck to all!

I can confirm same issue, rolled back automatically to the old driver that I had replaced - that said I haven't had any issues since I upgraded driver earlier this week.
