Symptoms
- Taskbar and desktop icons briefly disappear then reappear
- Screen flickers as Explorer restarts itself
- Happens repeatedly, sometimes every few minutes
- May coincide with specific actions like opening certain folders or using certain software
Likely causes
- CommonFaulty or conflicting shell extensionThird-party add-ins to Explorer are a very frequent cause of repeated crashes.
- CommonCorrupted system files related to the shellDamage to core Windows components that manage the desktop and Explorer can cause repeated crashes.
- PossibleOutdated or corrupted graphics driverSince Explorer renders visual elements, a driver problem can cause repeated crashes.
- PossibleMalware interfering with system processesSome malicious software specifically causes instability in core Windows processes.
- Less commonCorrupted user profileProfile-level corruption can cause repeated Explorer crashes specific to that user account.
What to do
- Open Task Manager and check the Windows Logs section of Event Viewer (search 'Event Viewer,' then Windows Logs > Application) for Explorer-related crash entries, noting any specific module or file mentioned.
- Use a tool like Microsoft's Autoruns (from Sysinternals) to review and disable non-Microsoft shell extensions one at a time to isolate a conflicting one.
- Update your graphics driver directly from the manufacturer's website.
- Run 'sfc /scannow' and 'DISM /Online /Cleanup-Image /RestoreHealth' to repair damaged system files.
- Run a full antivirus/anti-malware scan to rule out malware as the cause.
- Try signing into a different or new user account to see if the crashes are specific to your profile.
- If crashes are isolated to your profile, back up your files and create a fresh profile to migrate into.

If disabling shell extensions and repairing system files doesn't stop repeated Explorer crashes, a technician can perform a deeper diagnosis using crash logs.
