# WinObjEx64
[](https://ci.appveyor.com/project/hfiref0x/winobjex64)
## Windows Object Explorer 64-bit
WinObjEx64 is an advanced utility that lets you explore the Windows Object Manager namespace. For certain object types, you can double-click on it or use the "Properties..." toolbar button to get more information, such as description, attributes, resource usage etc. WinObjEx64 let you view and edit object-related security information if you have required access rights.
# System Requirements
WinObjEx64 does not require administrative privileges. However, administrative privileges are required to view much of the namespace and to edit object-related security information.
WinObjEx64 works only on the following x64 Windows: Windows 7, Windows 8, Windows 8.1, and Windows 10/11, including Server variants.

1. Requires driver support (see "Driver Support" section).
2. Administrator privileges may be required.
3. Windows internals features unavailable on Wine/Wine-Staging.
4. Administrator privileges required for some named pipes.
### Driver support
WinObjEx64 supports two types of driver helpers:
1. **Helper for read-only access to kernel memory**:
- Default version uses the **Kernel Local Debugging Driver (KLDBGDRV)** from WinDbg.
- Requires:
- Windows booted in debug mode (`bcdedit -debug on`)
- WinObjEx64 running with administrator privileges
- **Custom helper driver versions** do **not** require Windows debug mode.
- Multiple third-party drivers can be used as helpers, though only the **WinDbg-type** driver is included by default.
2. **Helper to access object handles**:
- WinObjEx64 (any variant) **supports** Process Explorer driver v1.5.2 for opening processes/threads.
- Enable by running **both** Process Explorer and WinObjEx64 with administrator privileges.
**Note**: All driver helpers require WinObjEx64 to run with administrative privileges.
