Task List





(j2 Global Communications)

eFax Messenger DLL support utility.  Background task which provides background fax conversion, fax sending, and fax status reporting when you use  eFax Messenger  to view or send your faxes via the eFax.com service.

Recommendation :
Down to end-user requirements.  This task goes hand in hand with  eFax Messenger  itself (J2GTray) and is usually started automatically through the  Startups  tab of  The Ultimate Troubleshooter.  Read our notes on  eFax Messenger  – if you decide you do want to have  eFax Messenger  automatically starting at Windows boot‑up, then also leave this task alone on the  Startups  tab of TUT;  if, on the other hand, you choose not to have  eFax Messenger  starting up automatically at Windows boot‑up, then disable this task as well.  This task normally uses between 3Mb to 7Mb of memory.

Javaw Javaw.exe

(Sun Corporation)
Part of Sun’s Java for Windows.

Recommendation :
Leave alone – Sun’s Java is used by all Internet browsers (Netscape, Internet Explorer, Mozilla, Opera) and is essential to their ability to display many websites.




Microsoft Debugger Registrar for Java.  You will most likely never see this file in your Task List.  The only reason for inclusion in these pages is that there is a  hoax  virus warning message going around the Internet asking users to delete this file if they find it on their hard disk.  Do no such thing if you receive the message – this file is a legitimate Microsoft file which you should keep.




Intel Dynamic Application Loader Host Interface Service.  Service installed by the  Intel Management Engine  drivers.

The  Intel Management Engine  is a microprocessor, separate from the main Intel CPU, which is embedded in most Intel Core, Intel vPro and Intel Xeon processors.  It continues to be active even after your PC/laptop has been turned off (but it must still be connected to the mains or, in the case of a laptop, the battery must have some life in it).  The programming code which powers this microprocessor is called  “Intel Active Management Technology”.  The prime purpose of this separate microprocessor :  to enable communications with your system regardless of the operating system it runs, or whether it is turned ON or powered off.  Applications of this technology would include being able to identify, keep track of, or monitor devices on a network regardless of whether they are turned ON or OFF (using special remote management software), remotely starting devices (e.g. on a factory production line, or the remote starting every morning of all computerized tills in a major multi-floors department store), remote troubleshooting and recovery, and general management of computer systems, such as remote pushing of updates, whether they be BIOS updates or operating system updates, or, even, remote installation of a new Windows/Linux/other-OS setup (image) on the PC.  In the more recent versions of this technology, there is even the possibility of remotely “killing” the computer if it is stolen.

To make use of this feature, one either uses some of the Intel tools, e.g. the Intel Management Engine suite of software tools, or the tools that the motherboard manufacturer may have developed themselves.

This particular service is part of the Windows drivers for the  Intel Management Engine  which allows two things:  your PC to communicate with some of Intel’s remote asset management and remote configuration and troubleshooting software;  but, also, the ability to use the tools provided by your motherboard manufacturer to modify BIOS settings without having to try to catch the BIOS entry screen with the DEL, F1, or F2 key at boot‑up.

Recommendation :
Down to end-user requirements.

As you may have guessed by now, most of the features of the  Intel Active Management Technology  are, typically, for corporate networks spread over either many floors, or a large areas, or many offices, where it can prove a massive time saver in terms of remote management and diagnostics, remote fix, and remote troubleshooting.

So, unless you are on a large corporate network where your IT department actively uses this technology, or you are supported by an IT Technician/Firm which uses this technology  and  you are quite happy to make modifications to the BIOS via the BIOS interface rather than from within Windows, then and only then you can safely  uninstall Install Management Engine Components  from your PC.  Note, however, that if you do so you will end up with one device with a question mark against it in Device Manager, but on the plus side you will in the process get rid of a number of background processes that you will never use and which simply consume [small amounts of] your computer’s resources.  If that question mark in Device Manager really really bothers you, then you can go to this Intel page to download  only the driver  (as distinct from downloading the entire Management Suite) - https://downloadcenter.intel.com/search?keyword=intel+management+engine .

If you have any doubts, if you are unsure, simply leave the software running – the software does use resources, unnecessarily on most PCs, but not so extensively that it is worth risking having to re-install it.




Sun Java Update Checker task.  If JUSCHED below is running, and the time has come in its schedule for the PC to check for updates to the Java Runtime, then JUSCHED starts JUCHECK.  In turn JUCHECK checks the Sun website for updates to the Java Runtime.  If there are updates available, an icon appears in the System Tray to let you know.  Double-clicking on the icon enables you to download the updates, or cancel the reminder, or set the reminder to remind you again at a later date.

Recommendation :
As this task will only appear if JUSCHED is itself running, read our recommendation for  JUSCHED.




Sun Java Runtime Update Scheduler.  This task will appear in your Task List if you have Sun Java runtime installed and it is configured to automatically look for updates.  This task was first introduced in version 1.4.2 of the Sun Java Runtime and at the time of writing, 25‑Mar-2005, runs only on Windows NT4/2000/XP/2003.  For the layman :  Java is nowadays an essential piece of software for your browser as there are many web pages which use Java to display information.

Recommendation : 
We always recommend against having any software updating itself automatically, even if it prompts the user before applying updates.  Stay in control of your PC and disable this task as follows :  double-click on the  Java plug-in  icon in the Control Panel, go to the  Update  tab and uncheck  “Check for updates automatically”,  click  APPLY – this will disable  JUSCHED  from starting at boot-up.  If you want to update Sun Java at a later stage, simply go back to the same  Java plug‑in  icon in the Control Panel, to the “Update” tab, and click the  Update Now  button.

All of the tasks below, and many more, although not detailed on this page, are explained in full in The Ultimate Troubleshooter.
