Fix Explorer.exe application error in Windows

Microsoft's first fix for File Explorer failures is to bring Windows fully up to date. Several Explorer crashes on Windows 11 were caused by update bugs that later updates corrected.

1. On Windows 11, go to Start > Settings > Windows Update.
2. On Windows 10, go to Start > Settings > Update & Security > Windows Update.
3. Select Check for updates and install everything offered.
4. Restart the PC when prompted, even if Windows does not ask, so pending updates finish installing.
5. Sign in and use File Explorer as normal to see if the error box returns.

What causes the Explorer.exe application error?

Explorer.exe runs the taskbar, Start menu and File Explorer windows, so an error in it can blank the desktop as well as close a folder window. The error box names Explorer.exe, but the fault often sits in something that loads inside it.

Likely cause	Typical sign	Fix to try
Missing or damaged system files	Error appears at random, sometimes with a memory address	DISM then SFC
Third-party shell extension or startup app	Error on right-click, on sign-in, or in one folder	Clean boot
Known update issue	Black screen at sign-in, missing taskbar after an update	Install the latest cumulative update
Damaged startup files	Explorer never loads after sign-in	Startup Repair
Wider Windows damage	Nothing above helps	Reset this PC

How to repair explorer.exe in Windows 11 with DISM and SFC

DISM repairs the Windows image first, then System File Checker uses that image to replace damaged system files, including Explorer's own components.

1. Select Start, type cmd, right-click Command Prompt and choose to run it as administrator.
2. Select Yes in the User Account Control prompt.
3. Type DISM.exe /Online /Cleanup-image /Restorehealth and press Enter. Wait for it to finish.
4. Type sfc /scannow and press Enter.
5. Leave the window open until verification reaches 100%.
6. Restart the PC once the scan reports its result.

If DISM cannot reach Windows Update, Microsoft documents a version that uses a repair source: DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess, with the path replaced by your own repair source.

What the sfc /scannow results mean

Message	Meaning	Next step
Windows Resource Protection did not find any integrity violations.	System files are intact	Move on to a clean boot
Windows Resource Protection found corrupt files and successfully repaired them.	Damaged files were replaced	Restart and test Explorer
Windows Resource Protection found corrupt files but was unable to fix some of them.	Some files are still damaged	Run DISM again, then SFC, or use Reset this PC
Windows Resource Protection could not perform the requested operation.	The scan could not run normally	Run SFC again in Safe Mode

To read what SFC changed, run findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt" in the same elevated window and open the file on your desktop.
