Hi Goran Culibrk,
Welcome to Microsoft Windows.
I will suggest you to follow the steps mentioned below:
- Reset the folder options view
Organize > Folder & search Options > General > Browse Folders > Select “Open each folder in same windows”
- Organize > Folder & search Options > View > uncheck Launch folder windows in a new process.
- Open Registry editor by typing “regedit” in Run dialog box and hit enter.Navigate to the key “HKEY_CLASSES_ROOT\Directory\shell”. On the right hand side pane there is a value named “Default” double-click on this value & Set the value to “none“. Once you make this change, your folders should instantly be back to normal.You must start explorer (Restart/Logoff) for changes to take effect.
- Get your AntiVirus updated and thoroughly scan your computer as Virus may create an Autorun.inf file in each folder which may cause this problem as well.
Important : This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
