	"plain_text": "DebugView - Sysinternals\r\nBy markruss\r\nArchived: 2026-04-05 21:32:40 UTC\r\nBy Mark Russinovich\r\nPublished: March 26, 2026\r\n Download DebugView (1012 KB)\r\nRun now from Sysinternals Live.\r\nDebugView is an application that lets you monitor debug output on your local system, or any computer on the\r\nnetwork that you can reach via TCP/IP. It is capable of displaying both kernel-mode and Win32 debug output, so\r\nyou don't need a debugger to catch the debug output your applications or device drivers generate, nor do you need\r\nto modify your applications or drivers to use non-standard debug output APIs.\r\nNote\r\nDebugView v5.0 requires Windows 10 version 1809 (build 17763) / Windows Server 2019 or later.\r\nDebugView will capture:\r\nWin32 OutputDebugString\r\nKernel-mode DbgPrint\r\nAll kernel-mode variants of DbgPrint\r\nDebugView also extracts kernel-mode debug output generated before a crash from Windows crash dump files if\r\nDebugView was capturing at the time of the crash.\r\nDebugView has a powerful array of features for controlling and managing debug output.\r\nFeatures new to version 5.0:\r\nDark mode and modern UI: DebugView now features a completely redesigned interface using Windows\r\nXAML Islands technology. The UI automatically follows the system-wide light or dark theme setting, with\r\ndark mode applied consistently to the title bar, menus, toolbar, dialogs, and the output list view. The\r\nmodernized toolbar and menu bar provide a visual style consistent with other Sysinternals tools such as\r\nProcess Monitor.\r\nAutomatic crash recovery: When DebugView detects that the previous session ended due to an ungraceful\r\nshutdown (such as a system crash), it automatically scans the Windows crash dump file, recovers pending\r\nkernel debug traces from the previous session, and displays them in the output window. This enables post-mortem analysis of kernel-mode debug output that was captured right up to the moment of a system failure,\r\nwithout any manual intervention.\r\nhttps://docs.microsoft.com/en-us/sysinternals/downloads/debugview\r\nPage 1 of 4\n\nUI virtualization for large captures: The output list view now uses owner-data virtualization, which\r\nmeans only the visible rows are rendered at any time. This allows DebugView to efficiently handle captures\r\ncontaining hundreds of thousands or millions of debug messages without excessive memory consumption\r\nor UI slowdown.\r\nDedicated PID column: A new Process ID column is displayed by default, making it easier to identify\r\nwhich process generated each debug output message. The PID column can be toggled on or off from the\r\nOptions menu.\r\nOn-demand UAC elevation: DebugView no longer requires administrative privileges at launch. It starts as\r\na standard user and requests elevation via a UAC prompt only when you enable kernel-mode capture or\r\nother operations that require elevated privileges.\r\nDPI-aware rendering: Menu icons, toolbar buttons, dialogs, and the output list all scale correctly on high-DPI displays.\r\nFeatures new to version 4.6:\r\nSupport for Windows Vista 32-bit and 64-bit\r\nFeatures new to version 4.5:\r\nSupport for log-file rollover: To better support long-running captures, DebugView can now create a new\r\nlog file each day, optionally clearing the display when doing so.\r\nFeatures new to version 4.4:\r\nSupport for Windows Server 2003 64-bit Edition and Windows XP 64-bit Edition for x64:DebugView\r\nnow captures kernel-mode debug output on 64-bit versions of Windows.\r\nClock-time toggle: you can now toggle between clock time and elapsed time modes.\r\nFeatures new to version 4.3:\r\nSupport for Windows XP SP2:DebugView now captures kernel-mode debug output on Windows XP SP2.\r\nMore highlighting filters: Many people have asked for more highlighting filters.\r\nLog file wrapping: A new log file option has DebugView wrap around to the start of the log file when the\r\nspecified size limit is reached.\r\nLarger buffers: Larger Win32 and kernel-mode buffers lessen the chance of dropped debug output.\r\nClear-output string: When DebugView sees the special debug output string \"DBGVIEWCLEAR\" it clears\r\nthe output.\r\nClient minimize-to-tray: You can now run the client minimized in the tray.\r\nFeatures new to version 4.2:\r\nKernel-hook bug fixed:DebugView sometimes mistakenly report that it couldn't hook kernel-mode debug\r\noutput on Windows XP and Server 2003.\r\nClient global-capture option: A new option allows the client to capture console Win32 debug output on\r\nTerminal Server systems when run from a non-console session.\r\nhttps://docs.microsoft.com/en-us/sysinternals/downloads/debugview\r\nPage 2 of 4\n\nFiltering improved: Filters can be much longer and now apply to Win32 process IDs when process IDs\r\nare included in the output.\r\nCrash-dump support improved: Several bugs related to extracting kernel-mode output from crash dumps\r\nare fixed and DebugView now loads resulting log files.\r\nMore highlight filters:DebugView now has 10 highlight filters, up from 5.\r\nInsert comments: A new menu item lets you insert comments into output.\r\nNew switches: New command-line switches allow you to specify history depth and load log files.\r\nBetter balloon tips: If an output line is wider than the screen its mouse hover balloon tip word wraps.\r\nFeatures new to version 4.1:\r\nSave and load filters: You can save and load filters, including the highlighting colors.\r\nLoad saved logs: You can now load a log file back into the DebugView output window.\r\nCapture boot-time kernel-mode debug output: Under Windows 2000, you can use DebugView to\r\ncapture debug output generated by drivers from the earliest point in the boot process.\r\nHere is a list highlighting some of DebugView's other features:\r\nRemote monitoring: Capture kernel-mode and/or Win32 debug output from any computer accessible via\r\nTCP/IP - even across the Internet. You can monitor multiple remote computers simultaneously. DebugView\r\nwill even install its client software itself if you are running it on a Windows 2000 system and are capturing\r\nfrom another Windows 2000 system in the same Network Neighborhood.\r\nMost-recent-filter lists:DebugView remembers your most recent filter selections, with an interface that\r\nmakes it easy to reselect them.\r\nDedicated PID column: A separate Process ID column shows which process generated each debug\r\nmessage, toggleable from the Options menu.\r\nClipboard copy: Select multiple lines in the output window and copy their contents to the clipboard.\r\nLog-to-file: Write debug output to a file as its being captured.\r\nPrinting: Print all or part of captured debug output to a printer.\r\nOne-file payload:DebugView is implemented as one file.\r\nCrash-Dump Support:DebugView can recover its buffers from a crash dump and save the output to a log\r\nfile so that users can send you the output your Windows driver generated right up to the time of a crash. In\r\nversion 5.0, this recovery is performed automatically on startup when an ungraceful shutdown is detected.\r\nThe on-line help file describes all these features, and more, in detail.\r\nDebugView v5.0 requires Windows 10 version 1809 (build 17763) or Windows Server 2019 or later. The modern\r\nUI is built on Windows XAML Islands, which requires this minimum OS version. Users on older versions of\r\nWindows should use DebugView v4.90.\r\nSimply execute the DebugView program file (dbgview.exe) and DebugView will immediately start capturing\r\ndebug output. DebugView starts as a standard user; you will be prompted for elevation via UAC only when you\r\nenable kernel-mode capture or other operations that require administrative privileges. Menus, hot-keys, or toolbar\r\nbuttons can be used to clear the window, save the monitored data to a file, search output, change the window font,\r\nand more. The on-line help describes all of DebugView's features.\r\nhttps://docs.microsoft.com/en-us/sysinternals/downloads/debugview\r\nPage 3 of 4\n\nIf a previous DebugView session was active during a system crash, DebugView will automatically detect the\r\nungraceful shutdown on the next launch, scan the crash dump file, and display any recovered kernel debug traces\r\nfrom the prior session.\r\nThis is a screenshot of DebugView capturing debug output. Note the modern dark mode interface with the\r\ndedicated PID column and highlighting filter.\r\n Download DebugView (1012 KB)\r\nRun now from Sysinternals Live.\r\nSource: https://docs.microsoft.com/en-us/sysinternals/downloads/debugview\r\nhttps://docs.microsoft.com/en-us/sysinternals/downloads/debugview\r\nPage 4 of 4",
