Windows 7: Very Strange

Hi,

I have a very strange problem. It happened just without any reason. When I try to open folder every time I open this in the new window. It's very annoying. I checked what setup is in "Folder options," and I have "Open each folder in the same window" but when I try to open every each time I open separate window.
I tried "Restore Defaults" button, but it didn't help.
Please give me some solution for this problem.

Have you tried option two in this link?

If the above fails I recommend doing option three in this link if the first two options fail again.

Just remember to backup your registry first.

Have you made this change in Control Panel>Folder options or just the folder in question?

OP says he has tried that Greg but tbh I can see why you suggested that as that was my initial thought.

Right, Mangoh. I was trying to remember if changing it in the Folder Options on the folder Organize tab will change it across the board.

If not then your suggestion to test System Files is spot on as there may be explorer corruption.

Oh I see mb

Forgot that you can change the folders options via control panel

On my PC, I'm positive that it is the same as the Control Panel link.

I set all of my templates/views from the folder I'm currently in, not the Control Panel.
After I disabled "Auto-Discovery", the settings have always worked as expected.

Hi,

I did (or checked) everything what Mangoh said, and it didn't help at all. Everything is set up like supposed to be but still when I open a folder, I open it in a separate window.

Okay please try what Greg said and if... that doesn't work I'd consider a repair install myself unless someone can recommend something better.

Confirm you are saving the choice by clicking OK in the Folder Options box.

If so, did SFC /SCANNOW Command find any system corruption?

Install, update and run a full scan with Malwarebytes.

If you have no infection then try System Restore .

Where did you get Windows 7? How is it activated?
