Download free Shell Extension Manager

Disable all thumbnail and preview handlers, restart Explorer, and then re-enable them one by one. ShellExView makes these invisible extensions visible so you can manage them. A single badly coded extension can slow down your entire file browsing experience or cause Explorer to crash. The issue is that Windows loads these extensions every time you interact with Explorer. A shell extension is a small piece of software (usually a DLL file) that plugs into Windows Explorer to extend its functionality.

Understanding the Interface

On Windows Vista, 7, 8, 10, and 11 — yes, administrator privileges are required for full functionality. ShellExView simply writes a registry value that tells Windows to skip loading them. For static entries, use NirSoft’s companion tool ShellMenuView instead. Removing unwanted items from the Windows right-click menu is ShellExView’s primary use case.

Classic Shell

Windows has no built-in interface for viewing or managing shell extensions. The problem with shell extensions is that they accumulate over time. It scans your Windows installation and displays a complete list of every shell extension registered on the system. Fix slow right-click menus, stop Explorer crashes, and take control of every context menu handler on your system. You can plug the drive into any Windows PC — even one without internet — and immediately diagnose shell extension problems.

• This re-enables every extension in the list, including ones that were already enabled (pressing F8 on an enabled extension does nothing, so it is safe).
• A single badly coded extension can slow down your entire file browsing experience or cause Explorer to crash.
• The 64-bit version of ShellExView (shexview-x64.zip, ~140 KB) runs natively on 64-bit Windows and can display both 64-bit and 32-bit shell extensions.
• The only native option is manually navigating the registry with Regedit, which requires you to know the exact CLSID keys and is both tedious and risky.
• The only traces ShellExView leaves on a system are the disable flags it writes for extensions you chose to disable.
• ShellExView needs to read and write to registry keys under HKEY_LOCAL_MACHINE and HKEY_CLASSES_ROOT, which are protected areas that require elevated permissions.

The only native option is manually pokies online navigating the registry with Regedit, which requires you to know the exact CLSID keys and is both tedious and risky. When a right-click takes 5 to 10 seconds to appear, the usual suspect is a misbehaving shell extension. The tool is popular among IT professionals, system administrators, and advanced users who need to troubleshoot Explorer-related issues.

Re-enabling an extension removes that registry entry, restoring the original state. It reads shell extension data from the Windows registry and displays it. This is faster when you have many third-party extensions to test. The first thing most users do is hide built-in Windows extensions. This is the fastest way to group extensions by company or type. On a typical Windows 10/11 machine, you will see 200 to 400 registered shell extensions.

If Explorer crashes immediately when you open certain folders, the problem is likely a thumbnail or preview handler extension. Explorer crashes and the “Windows Explorer has stopped working” error are frequently caused by a faulty shell extension. Sort by Type and check how many “Icon Overlay Handler” entries are active.

Batch operations let you disable multiple extensions at once. Select any extension and press F7 to disable it or F8 to re-enable it. Nothing hides from this scan — even disabled or broken entries show up.
