Time and again it is possible that icons in Windows 10 that shows up on programs, documents, pictures, etc. may get messed up and corrupted, and as a result you could see icons mismatched and distorted. The problem is more prominent in cases where the PC was upgraded from earlier version of Windows to Windows 10.
Before proceeding to fix it, let me quickly brief why this happens at first place. Windows 10 saves the icons in a cache section so that it can be quickly loaded. It would take lot of time to just display the files and their icons if Windows digs out each item from hard disk. That’s the reason Windows builds icon cache every now and then you launch explorer and things like that. But sometimes this cache can go haywire due to script errors and memory overruns and as a result icons get cross-linked and you will see wrong icon for a extension. The easiest fix to this problem is to rebuild icon cache. Let’s get started.
Tip: Before proceeding make sure to save all documents and close everything because at last step your PC will restart instantly. Also, if you are copying or moving any large files in the background, make sure to finish them before proceeding further as explorer will be killed in the process and copy/move will be terminated.
Type Command Prompt in the taskbar search box and select Command Prompt from the list.
Copy and paste ie4uinit.exe -ClearIconCache in the command line tool and hit enter.
Copy and paste taskkill /IM/F and hit enter. This will kill explorer.exe process.
Copy and paste DEL /A /Q “%localappdata%\” and hit enter.
Copy and paste DEL /A /F /Q “%localappdata%\Microsoft\Windows\Explorer\iconcache*”
Finally, copy and paste shutdown /r /f /t 00 and hit enter. Windows will immediately restart and icon cache should be flushed and ready to reload. That’s it. Did icon rebuilding work for you? Do let is know in comments below.
