Windows 10: default folder explorer.exe

Hi,
I have a problem on windows 10... sudenly there was a change to the default program that opens folders from explorer.exe to cmd. So if I doubleclick a folder it says there is no program assigned to it and doesnt open. Still if I rightclick and click open it opens no problem. How can I make explorer.exe open folder as default again?
Thanks.

Windows 10 - File Explorer Association

HKEY_CLASSES_ROOT\Folder\shell\open

MultiSelectModel REG_SZ Document
HKEY_CLASSES_ROOT\Folder\shell\open\command

(Default) REG_EXPAND_SZ %SystemRoot%\Explorer.exe

DelegateExecute REG_SZ {11dbb47c-a525-400b-9e80-a54615a090c0}

Something caught up with my registry. Now what should I do?

 

Random acces denied to files or folders

As I rebooted windows the problem folder dissapeared.

So I tried to reproduce the issue with another folder.

And I think I got the hang of it.

It goes like this:

When I try to delete a random folder or a group of folders sometimes it fails to delete one folder.

The folder is visible in Explorer but not accesible.

So I used task manager to kill explorer.exe process and run explorer.exe again.

After this, Explorer does not show the folder.

So it seems like a random delete issue. As the folder it is actually deleted but Explorer keeps showing me a non existing folder. Therefore the access denied issue.

As I killed Explorer.exe process or reboot Windows, the folder does not appear anymore.

Any thoughts?

 

Hi, if you have no restore points or disk images to back up your system so you can recover without technical help, please try this
Default File Type Associations - Restore in Windows 10 - Windows 10 Forums

and find 'Folder'

Follow the instructions and post back the result. Good luck!

 

I already tried this and it didnt work :-/

 

Ok, good, is there anything else you've tried?

Technical fixes here.
Windows 7 Double Click on Folder opens Command prompt
Granted, these are for Win 7, but I'd guess these should be applicable.
Therefore, before you try this, make sure
- System Restore is enabled
- set a manual restore point.

Another option (I can't tell you if it's any different to what you've tried, of course) but useful to know:
Tweaking.com's Repair tool.

Cautious, helps you back up before a repair, select only the repair you need. (Folder assocation)

 

Just in case. Please check the following settings..............
Open File Explorer Options > General tab .
Under Click items as follows heading, is there a dot at Double click to open an item ?
If not, dot it > OK when done.

 

Thank you that windows 7 types really helped. So if someone else have this problem: Just go to regedit andin HKEY_CLASSES_ROOT\Directory delete folders with "cmd" name
or just call your friend with same system and get his Directory regs.
