Question concerning HDMP files

Hello all,

I wonder if anyone can explain the ReportQueue files that I have located in a Windows Temp folder for Vista (Ultimate 64bit). I have an HP 9500 Pavillion laptop and have had a great deal of trouble today with Ad Aware 2007 by Lavasoft totally freezing during scans and then crashing my computer. I eventually uninstalled it and ran a cleanup and defrag only to find that I have a new 2GB file (evidently created today) in C:\ProgramData\Microsoft\Windows\WER\ReportQueue\Report1ecfd905\WERD945.tmp.hdmp

I am denied access to the file, so I have no idea what it is, how I got it, or whether it caused the problems with the Ad Aware scans. I'd love to know if it can be deleted and... if all of the other so called report files in the Windows temp folder that contains them can go, too. In addition, if I am denied access exactly how can they be removed??
 
To resolve this problem simply click:

Start --> ControlPanel -->> Problem Reports and Solutions
and then click: Clear solution and problem history
cleans up all the content of ReportQueue folder.

Delete of C:\$Extend\$UsnJrnl:$J:$DATA



Delete C:\$Extend\$UsnJrnl:$J:$DATA safely 1 command!!!

Have you ever noticed when you run O&O Defrag and there's always those pesky files named: C:\$Extend\$UsnJrnl:$J:$DATA that just will not defrag no matter what you try?

Well now you can just remove it!!! Right click command prompt, run as administrator:
fsutil usn deletejournal /n c:

Below is a FAQ item from the website:

How do I defragment "C:\$Extend\$UsnJrnl:$J:$DATA"?
  This huge file is used by Windows to track changes in other files and cannot be defragmented. You can delete it by entering the following on the Run commandline (Windows 2003/XP/Vista, not Windows 2000), it can take several minutes to finish.

How do I defragment "C:\$Extend\$RmMetadata\$TxfLog\$Tops:$T:$DATA"?

How do I defragment "C:\$Extend\$RmMetadata\$TxfLog\$Tops:$T:$DATA"?
 
This is a special NTFS system file used by the Windows Transactional Resource Manager. MyDefrag cannot move or defragment this file. It can be cleaned with the fsutil command, see below. Do not try to delete this file by hand.
Use the following commandline to see information about the TOPS files: fsutil resource info c:\

The following commandline will instruct Windows to clean (not delete) the TOPS file at the next reboot: fsutil resource setautoreset true c:\

Device Manager Does Not Display Devices Not Currently Present in Windows

http://support.microsoft.com/kb/241257

Devices that are installed but are not currently connected to the computer (such as a Universal Serial Bus (USB) device or "ghosted" devices) are not displayed in Device Manager, even when you use the Show hidden devices command.

WORKAROUNDTo work around this behavior and display phantom devices when you use the Show h...To work around this behavior and display phantom devices when you use the Show hidden devices command:

Click Start, point to Programs, point to Accessories, and then click Command Prompt.

At the command prompt, type the following lines, pressing ENTER after each line

set devmgr_show_nonpresent_devices=1

cd\%SystemRoot%\System32

start devmgmt.msc

where %SystemRoot% is the folder in which Windows 2000 is installed.





Troubleshoot the devices and drivers in Device Manager, as required.



NOTE: You must first select show hidden devices on the Device Manager View menu before you can see devices that are no longer present in the system.

When you are done troubleshooting, quit Device Manager, and then close the Command Prompt window. Closing the window clears the variable you set in step 2 and prevents ghosted devices from being displayed when you use the Show hidden devices command.

NOTE: When you quit Device Manager and close the Command Prompt window, the set devmgr_show_nonpresent_devices=1 variable is turned off so you cannot see the phantom devices.



An alternative approach, for developers or power users who need this feature enabled constantly, is to set this environment variable globally. To do so, perform the following steps:

Right-click My Computer.

Click Properties.

Click the Advanced tab.

Click the Environment Variables tab.

Set the variables in the System Variables box.

NOTE: You should use this method only for troubleshooting or development purposes, to prevent users from accidentally uninstalling a required device that is not currently present (such as a USB device or docking station that is not currently connected to a laptop computer).
