Recently, I installed and tested the QTTabBar software by hand. After regular installation and uninstallation, I was really confused. After uninstalling, various problems appeared in the system. First, double-clicking files and folders automatically opened the cmd window. I finally fixed it. Then, when opening the file explorer explorer.exe, I was stuck with various fancy prompts "This file does not have an application associated with it to execute. Please install the application. If the application is already installed, please create an association in the "Default Application Settings" page."
Serious warning: QTTabBar This software is really poisonous. It tampered with and replaced a lot of explorer registry entries during installation, leaving a bunch of junk registry entries after uninstalling. If you use the cleaning and optimization tool to scan and clean it, congratulations, I hope you will solve all kinds of strange problems. Friends, please do not try it on non-test systems~
Repair Process:
1. Copy the following code into txt text, save it as a .bat file, double-click to run:
taskkill /f /im explorer.exe
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Icons" /v 29 /d "C:\Windows\system32\imageres.dll,154" /t reg_sz /f
reg add "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Icons" /v 29 /d "C:\Windows\system32\imageres.dll,154" /t reg_sz /f
reg add "HKEY_CLASSES_ROOT\lnkfile" /v IsShortcut /t reg_sz /f
reg add "HEKY_CLASSES_ROOT\piffile" /v IsShortcut /t reg_sz /f
start explorer
According to the prompts, if some table entries fail to be imported, you need to open the regedit registry, then expand the corresponding path and add it manually.
After completing the above registry repair actions, you can open the File Explorer normally by using the Win+E shortcut key and directly double-clicking the C:\Windows\SysWOW64\explorer.exe program, and the prompt "There is no application associated with it..." is no longer displayed.
However, when I click on the File Explorer icon locked to the taskbar, it still cannot be opened normally, no matter how many times I try to unbind and rebind it, it doesn't help.
**2. Based on the retrieved public information, save the following code to the .reg file and try to import the registry: **
Windows Registry Editor Version 5.00[[HKEY_CLASSES_ROOT\Folder\shell\explore\command]"DelegateExecute"="{11dbb47c-a525-400b-9e80-a54615a090c0}"[HKEY_CLASSES_ROOT\Folder\shell\opennewprocess\command]"D elegateExecute"="{11dbb47c-a525-400b-9e80-a54615a090c0}"[HKEY_CLASSES_ROOT\Folder\sh ell\opennewwindow\command]"DelegateExecute"="{11dbb47c-a525-400b-9e80-a54615a090c0}"
It’s no use~
Then I tried to modify the various registry key values and group policy rules mentioned in the information, but to no avail~
**3. When I felt that I would never fall in love again, I suddenly remembered the 36X digital series family bucket protection software I used when I first came online. Although the computer has been running naked for many years, it has become a dead horse: **
After a one-click scan and repair, it was amazing. The file explorer locked to the taskbar could be opened smoothly. As expected, only magic can defeat magic...
Postscript:
In the end, I didn't figure out which registry key corresponded to the file explorer on the taskbar, so I left it at that. I was tired and didn't want to worry about it anymore. Just because I installed and tested QTTabBar with a cheap hand, I wasted most of my rest time on Saturday!
