Troubleshoot Windows startup/shutdown with Bootlog Analyser

Bootlog Analyser allows troubleshooting of Windows startup and shutdown with Windows 95/98/Me/NT4/2000/XP.

Bootlog Analyser uses the Windows generated startup log file (bootlog.txt or ntbtlog.txt).
Bootlog.txt file records the progress of the Windows startup (boot) process. It is created if you request a logged boot, and is also created automatically by Windows if Windows detected that the previous boot was unsuccessful.
You can create a new Boot Log file by choosing option [2] "Logged (\BOOTLOG.TXT)" from the Windows 95 Startup Menu. You can display this menu manually by pressing the F8 (or CTRL) key during system startup, just after the system beep and before the Windows logo appears.

Bootlog Analyser

Press on the tick button to read current Bootlog file. Usually it is located in the c:\bootlog.txt (Windows 9X/Me) or in the c:\windows\NTBTLOG.TXT(Windows NT4/2000/XP). Choose File-Open to open file from another location. You can see used file name and its date in the status bar at the bottom of the window. Boot duration parameter determines how long the Windows startup process runs. To analyse the failures click on the Failure column and go to the top of the list. The failed items are marked by "!!!" signature.

What failed? Why? How to resolve the problems?

Bootlog.txt may contain the following lines, even though your computer is running properly:

  • LoadFailed = dsound.vxd
  • LoadFailed = ebios
  • LoadFailed = ndis2sup.vxd
  • LoadFailed = vpowerd
  • LoadFailed = vserver.vxd
  • LoadFailed = vshare
  • InitCompleteFailed = SDVXD
On a computer that is running Windows 98 may also contain the following lines: Deviceinitfailed = MTRR SysCritInitFailed = JAVASUP DeviceInitFailed = MTRR These load failures do not necessarily indicate a problem. It is common for some, if not all, of these load attempts to fail, depending on your system configuration. You may get more information about the causes of specific types of load failures in the Microsoft Knowledge Base Article - Q127970.

Other errors may be very important for Windows startup. If you have LoadFailed error check that the file is really exists. The core drivers is located in the \WINDOWS\SYSTEM\IOSUBSYS\ folder. Also check the \WINDOWS\SYSTEM\VMM32\ and C:\WINDOWS\SYSTEM.

Optimizing startup

To optimize your startup check the delays. Click on the Delay column to sort this table by delays. Inspect the delays. Be careful. If you see a large delay on the item "Enumerating ..." this doesn't mean that this action caused the delay. This delay is caused by the previous item. Below the "Enumerating" event you should find the associated "Enumerated" event. The enumeration delay is printed on the "Enumerated" event.

Useful Tips

To quckly restore the original sort order of Bootlog.txt file click on the "Show in Unsorted Order" button. To analyse bootlog file in spreadsheet software click on the Save button to export this file to the CSV file format. This file format may be easily opened with Microsoft Excel and other software.

To search the list press CTRL+F or click on the Search button.

Bootlog Analyser is included in the RegRun Suite Gold version only.

They say
"RegRun Security Suite is one of those very rare tool kits that no one who is serious about protecting their PC should ever be without. This toolkit covers all the bases when it comes to eradicating the attempted security threats from malware that we all face - daily. The near real time tech support, direct from Greatis, is nothing sort of superb, something that can be rarely said these days! I have no hesitation in recommending this suite to anyone."

You guys are awesome!!!!

Bob Schmulian:
Absolutely love it and have recommended to many people!

Ian Robinson:
It is FANTASTIC! It has saved my life on more than one occasion since I purchased it less than 6 months ago. I now would not run my system without it... it's worth many times the cost! The service and support are terrific. Helpful - friendly - and accommodating; and generally a reply is received within 12 hours. Just great.

Theodore Soucie:
Since RegRun was installed my system is more stable. I use to experience freezeup daily. I have not had a crash.
