Well, I do not care if someone will ever going to read this article, but I just wanna share the fix that I dd that really worked fir this error or bug.

FIX: Clicking folder always open New Window

I really do not know the culprit why this happened, but again, thank you Google for the fix. There are 3 fixes that you might wanna try to solve this problem.

Clicking folder always open New Window.

First solution:

1. Try opening a Folder, any folder will do.
2. Find and click Organize > Folder and search options. You can also go to Control Panel > click View by > Small icons > Folder Options.
3. In the General tab, under the Browse folders section > select Open each folder in the same window.
4. Click Apply, and then OK.

Second solution:

1. Copy the code below and paste it in a Notepad. Save the file as anyfilename.bat

@echo off

:: 32 bit and 64 bit
IF EXIST "%SystemRoot%\System32\actxprxy.dll" "%SystemRoot%\System32\regsvr32.exe" "%SystemRoot%\System32\actxprxy.dll"
IF EXIST "%ProgramFiles%\Internet Explorer\ieproxy.dll" "%SystemRoot%\System32\regsvr32.exe" "%ProgramFiles%\Internet Explorer\ieproxy.dll"

:: 64 bit only (32bit on 64 bit)
IF EXIST "%WinDir%\SysWOW64\actxprxy.dll" "%WinDir%\SysWOW64\regsvr32.exe" "%WinDir%\SysWOW64\actxprxy.dll"
IF EXIST "%ProgramFiles(x86)%\Internet Explorer\ieproxy.dll" "%WinDir%\SysWOW64\regsvr32.exe" "%ProgramFiles(x86)%\Internet Explorer\ieproxy.dll"

Third solution:

1. Scan your PC or laptop computer for file errors or corrupted files.
2. Go to Start > type cmd and press Enter. Run Command as Administrator.
3. Inside cmd, type sfc /scannow and hit Enter.
4. Just wait for some time until scanning finishes.
5. Done!

The third solution worked for me, and it really stops making opening a new window when clicking a folder to open a subfolder.
