This .reg file is useful if you wish a machine to restart without the need to logon.  Naturally this is a completely insecure setting.  The main business case is for AutoAdminLogon is in Libraries, or when installing machines via scripts.

Please note, that unlike the other .reg files there is no way this will work unless you edit the file because the DefaultPassword in the file is "z1!8line1".

In fact, you may better off making your own AutoAdminLogon .reg file, see the next item below.

Build Number and PaintDesktopVersion

What this .reg file does is add a message displaying the Build Number to the bottom right of you desktop.

Copy the instructions below into a text file, save the file with .reg extension, for example Build.reg. Then refer to How to transfer the .reg settings into the registry.

Windows Registry Editor Version 5.00

How to Create Your Own .reg Files

Applying .reg files is useful, but best of all, you could create your own .reg files.  Here is how you can do it:

  1. Launch Regedit (Start, Run, Regedit)
  2. Navigate to the area of the registry you are interested in.
  3. Select File (menu), Export and save as .reg file.
  4. Note: Export Range at the bottom of the diagram and choose:  Selected branch.

Export Registry.  How to make .reg files

Once you have mastered the technique to create .reg files, keep a look out for repetitive tasks where you need the same settings on multiple servers.  Enabling the Security Tab on Exchange Servers is a classic use for this .reg file technique.

Monitor Your Network with the Real-time Traffic AnalyzerSolarwinds Real-time Traffic Analyzer

The main reason to monitor your network is to check that your all your servers are available.  If there is a network problem you want an interface to show the scope of the problem at a glance.

Even when all servers and routers are available, sooner or later you will be curious to know who, or what, is hogging your precious network’s bandwidth.  A GUI showing the top 10 users makes interesting reading.

Another reason to monitor network traffic is to learn more about your server’s response times and the use of resources.  To take the pain out of capturing frames and analysing the raw data, Guy recommends that you download a copy of the SolarWindsfree Real-time NetFlow Analyzer.

Troubleshooting AutoPlay Using Regedit

Since the Local Group Policy Editor is not supplied with Windows Home editions, you will need to employ regedit to achieve the same result.

Open regedit and locate the following key:

Change:  NoDriveTypeAutoRun to 0x91

If necessary create this key as a DWORD.

Increase the Number of Simultaneous Downloads

The keyword is ‘Simultaneous’,  in early versions of Windows Explorer you could only download 2 files at a time.  While Windows Explorer 8 increases this number to 6.  Here is how edit the registry and so achieve 10.

Internet Explorer 8 Settings.

Windows Registry Editor Version 5.00
"iexplore.exe "=dword:0000000a

Note: dword:0000000a is ten in decimal.

Note: Observer that Internet … Explorer wraps to the next line.

Internet Explorer 7 and Lower Settings


Windows Registry Editor Version 5.00
"iexplore.exe "=dword:0000000a

Guy Recommends: The Free IP Address Tracker (IPAT) Free IP Tracker

Calculating IP Address ranges is a black art, which many network managers solve by creating custom Excel spreadsheets.  IPAT cracks this problem of allocating IP addresses in networks in two ways:

For Mr Organized there is a nifty subnet calculator, you enter the network address and the subnet mask, then IPAT works out the usable addresses and their ranges.  For Mr Lazy IPAT discovers and then displays the IP addresses of existing computers.
