- Frequently Asked Questions
- Conclusion
After Microsoft released Windows 10 October 2018 Update (Windows 10 1809), cloning Windows 10 1809 to a USB drive and booting from it will result in the following blue screen error: Stop Code: DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS What failed: dump_WppRecorder.sys

To fix this issue, download and install the latest version of Hasleo WinToUSB, and use it to clone Windows 10 1809 to an external hard drive or a USB flash drive. Then you can resolve Blue Screen Errors (e.g., dump_WppRecorder.sys) by "Driver Unloaded Without Cancelling Pending Operations".
The dump_WppRecorder.sys BSOD was a well-known compatibility issue specific to Windows 10 version 1809 when deployed as a portable Windows To Go workspace. This error occurred because the Windows 1809 boot process attempted to unload the WppRecorder driver without properly cancelling pending I/O operations, a timing-related bug that Microsoft addressed in subsequent Windows 10 releases. Understanding this history helps contextualize why later Windows 10 versions (1903 and newer) provide a more reliable Windows To Go experience without requiring workarounds.
Below we will detail how to use Hasleo WinToUSB to clone Windows 10 1809 to a USB drive as a Windows To Go workspace.

Step 2. Click "Select installation source" and then select "Current Windows OS" from the pop-up list.
