DiskLED is Now Open Source

DiskLED is a tool I wrote a while ago that displays performance counter data using an animated system tray icon. It comes with a graphical configuration dialog that lets you choose from all performance counters available on the local system – you can monitor network throughput just as easily as hard disk activity or memory […]

Delprof2 & SetACL Studio Free for Commercial Use

I am happy to announce that my tools Delprof2 and SetACL Studio are now free to use, both for individuals and corporations. Previously, Delprof2 was only free to use commercially if an organization allowed us to use their name in our marketing. SetACL Studio was not available for free at all. If you like either […]

FileIOTest – Times the Duration of File IO Operations

FileIOTest is a command line tool that tests the speed of local or remote (SMB) storage by performing some common file IO operations repeatedly and measuring the duration.

Finding and Removing Orphaned SIDs in File Permissions, or: Busting the Ghosts Built Into Windows 7

Due to a lack of visibility permission cleanup is performed far less frequently than it could, and probably should. As a result, ghost ACEs (permissions from deleted accounts) linger in the dark corners of the file system, threatening the unsuspecting admin with the horrors of unresolvable SIDs.

HowTo: ReACLing a File Server in a Domain Migration with SetACL 3.0

When you are planning a migration of user accounts between domains one task always pops up pretty quickly: reassigning the permissions of the users in the source domain to the corresponding users in the target domain, in other words reACLing the file server.

Half a Million Downloads of SetACL

Last month SetACL reached the magic number of 500,000 downloads. That is a lot, especially for a command-line tool which is focused on a very specific aspect of system administration. It took roughly nine years to get from 0 to 500,000. During that time people from 194 different countries visited SetACL’s web site. Those are […]

How to Easily Monitor System Performance with the new DiskLED 1.1

DiskLED is a small tool that displays performance counter data using an animated system tray icon. The new version 1.1 comes with a graphical configuration dialog that lets you choose from all performance counters available on the local system – you can monitor network throughput just as easily as hard disk activity or memory usage.

DiskLED – A Flexible Hard Disk and General System Activity Indicator System Tray Applet

What do you do when your computer reacts sluggishly to even the simplest commands? You probably look at its hard disk LED to determine if the disk is busy, because if it is, the only thing that really helps is waiting (apart from buying a faster disk or SSD). Problem solved – if you are […]

ParseCitrixLicense Now Supports XenDesktop Licenses, Too

A few weeks ago I published the tool ParseCitrixLicense which displays the contents of Citrix license files in a human-readable form. The original version 1.0 did not support XenDesktop licenses, for the simple reason that I had none to test my program with. Recently my colleague Nicholas Dille provided me with a XenDesktop eval license […]

Free Tool to Help You Better Understand What is Inside a Citrix License File

Update: Version 1.1 supports XenDesktop Licenses in Addition to XenApp Licenses Most Citrix products rely heavily on license files. While the basic format of a license file is somewhat documented, most fields used in license files are not. This makes understanding their contents difficult. It does not help that the license files can hardly be […]

Free Tool – List Registry Links (REG_LINK)

Recently I got into a very interesting discussion with my colleague Nicholas Dille on various aspects of Windows x64. One question he brought up was especially intriguing: knowing about registry redirection, it is not astonishing to find that the 32-bit version of the registry key HKLM\Software\Classes (aka HKCR) gets to be HKLM\Software\Classes\Wow6432Node. But there is […]

Free Tool: Refresh the Desktop Programmatically

I recently had the requirement to refresh the Windows desktop after certain changes had been made to Explorer’s registry entries. This seems simple at first: klick on any item on the desktop and then press F5. It wasn’t, though. The registry changes would be made upon logon by a software installation agent. It was expected […]
