Windows 7 and Windows Server 2008 R2, while lauded for their stability and user-friendliness, were not without their occasional quirks. One such issue that plagued some users was a random crashing of Windows Explorer, the file management interface integral to the operating system. This article delves into the details of this problem, its cause, and the Microsoft-provided solution, Hotfix KB2638018. We will also explore alternative download sources for the fix, ensuring users can access the necessary patch even if the primary source is unavailable.
The Problem: Random Windows Explorer Crashes
Users experiencing this issue reported that Windows Explorer would unexpectedly close or become unresponsive. This could happen while simply browsing files, copying data, or performing other routine file management tasks. The unpredictable nature of these crashes was particularly frustrating, disrupting workflow and potentially leading to data loss.
The specific scenario in which this issue was observed involved computers running Windows 7 or Windows Server 2008 R2 within a network environment. While the crashes appeared random, a common factor was identified: Network Discovery.
Network Discovery and Its Role
Network Discovery is a Windows feature that allows a computer to detect and interact with other devices and resources on a network. When enabled, it actively searches for shared folders, printers, and other network services, making it easier for users to access these resources. However, in certain circumstances, this feature could inadvertently trigger the Windows Explorer crashing issue.
The Root Cause: Faulty Module Unloading
The underlying cause of the problem was traced to the Fdwnet.dll module. This module is responsible for handling certain network-related functionalities within Windows Explorer. The Microsoft Windows Explorer Crash in Windows 7 Hotfix KB2638018 addresses a flaw in how this module was being unloaded, leading to instability and the subsequent crashes. Specifically, the Fdwnet.dll module was being incorrectly unloaded, causing a system error that manifested as a Windows Explorer crash. This incorrect unloading process was directly linked to the presence of Network Discovery being enabled.
The Solution: Hotfix KB2638018
Microsoft recognized this issue and released Hotfix KB2638018 to address it. This hotfix specifically targets the faulty unloading of the Fdwnet.dll module, resolving the instability and preventing the random Microsoft Windows Explorer Crash in Windows 7 Hotfix KB2638018.
The hotfix was initially made available through the Microsoft Knowledge Base. The standard process involved checking for a "Hotfix download available" section within the Knowledge Base article. If present, users could directly download and install the patch. If the download link was missing, users were instructed to contact Microsoft Customer Service and Support to obtain the hotfix.
Applying the Hotfix
Before applying Hotfix KB2638018, it’s crucial to ensure that your system meets the prerequisites. The hotfix is specifically designed for computers running either Windows 7 or Windows Server 2008 R2. Applying it to other operating systems may lead to unexpected behavior or system instability.
The installation process typically involves downloading the hotfix package, extracting its contents, and running the executable file. It’s recommended to close any open applications and restart the computer after the installation is complete to ensure that the changes take effect.
Important Considerations
While Hotfix KB2638018 effectively addresses the described Windows Explorer crashing issue, it’s essential to understand its scope. The hotfix is specifically designed to correct the problem caused by the faulty unloading of the Fdwnet.dll module. It may not resolve other issues that could also lead to Windows Explorer crashes.
If you experience persistent Windows Explorer crashes even after applying the hotfix, it’s recommended to investigate other potential causes, such as:
- Corrupted system files
- Conflicting software
- Outdated drivers
- Hardware issues
Availability and Download Links
As an older hotfix, directly obtaining Microsoft Windows Explorer Crash in Windows 7 Hotfix KB2638018 from official Microsoft channels might be challenging. However, it can often be found on third-party driver download sites.
Original Microsoft Download Link: The original Microsoft download link is likely unavailable due to the age of the hotfix. You may need to contact Microsoft Support to inquire about its availability, although this is unlikely to be successful.
Alternative Download Link:
While directly linking to a specific third-party download site carries risks (potential malware, outdated versions), a web search for "Download KB2638018" will yield several options.

Mitigation Strategies (If Hotfix Is Unavailable)
If obtaining the hotfix proves difficult, there are a few mitigation strategies that users can try to minimize the occurrence of Windows Explorer crashes:
-
Disable Network Discovery: While disabling Network Discovery limits the ability to easily access network resources, it can prevent the faulty unloading of the Fdwnet.dll module. To disable Network Discovery:
- Open Control Panel.
- Go to Network and Sharing Center.
- Click "Change advanced sharing settings" in the left pane.
- Under your current network profile, select "Turn off network discovery."
- Save changes.
-
Clean Boot: Performing a clean boot starts Windows with a minimal set of drivers and startup programs. This can help identify if a third-party application or driver is conflicting with Windows Explorer and causing the crashes.
-
System File Checker (SFC): The System File Checker is a built-in Windows utility that scans for and repairs corrupted system files. Running SFC can help ensure the integrity of the operating system and potentially resolve issues related to Windows Explorer crashes.
-
Check Event Viewer: The Event Viewer logs system events, including errors and warnings. Examining the Event Viewer logs can provide clues about the cause of the crashes and potentially identify specific applications or drivers that are involved.
