Startup Programs

Ever wonder how to do it if you want a certain program to run automatically whenever a machine boots up, or whenever a user logs in? The trick is in the registry.

When windows starts up, it will run all programs it finds in the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run.

Let’s do a simple experiment. Open up the registry by typing regedit into the open box (Start -> Run). Navigate to the above key. Click on the Run key on the left pane, then right-click on empty space on the right pane. Choose New -> String Value, and give it a name like test.

A new key named test has been created, but it has no value. Double-click on this newly created key test, and enter notepad.exe in the Value data box. Click OK, and close regedit.

Restart windows. After windows is restarted, login to any account, and you’ll see notepad opens up already.

If you want a particular program (or group of programs) to be run every time whenever a particular user logs in, you can put a shortcut to this program (or these programs) in this folder C:\Documents and Settings\[username]\Start Menu\Programs\Startup\. Replace [username] with the actual username. You can navigate to this folder through windows explorer.

This is useful if, for example, a user in the accounting department always runs the accounting program acct.exe whenever he/she logs in. You can put in this user’s Startup folder a shortcut pointing to this acct.exe. Make sure that this user has all privileges, permissions, credentials to run this program.

UniPrint VDI Edition licensing

UniPrint VDI Edition is to be installed on a desktop running Microsoft desktop Windows, i.e., XP or Vista.

The licensing model of UniPrint VDI Edition is different from the UniPrint SbC products. The VDI Edition uses a per-server and per-concurrent-users model.

You will need a machine to act as a UniPrint License Server, which is usually a UniPrint Spool Server.

Unlike the licensing of core UniPrint SbC products, you don’t need the following information:

• Environment: RDP only or ICA (ICA license includes RDP, so RDP can run on ICA license).
• Platform: 32-bit support or 64-bit support (64-bit license includes 32-bit support, so 32-bit platform can run on 64-bit license).

You will need the following information to generate a license file:

• The machine name on which UniPrint Spool Server is/will be installed.
• The IP address of the machine above.
• A serial number that you obtained from your supplier (a reseller, a distributor, or the vendor).
• The number of servers.
• The number of concurrent users.

How to find out machine name and IP address?

As you need the machine name and IP address in order to request a valid license, you need to know how to find out the information. There are several ways to find out the name and the IP address of your machine.

The easiest way is from a command window. To open a command window, click Start -> Run, then in the Open box, type cmd, and click OK. In the command window, type hostname to see the name of your machine, and type ipconfig to see the IP address of your machine.

Click here to see a larger image.

You can also find out the machine name by right-clicking My Computer (on the desktop or on the Start menu), and then choose Properties, then click on the Computer Name tab.

Click here to see a larger image.

If you cannot see My Computer on your desktop, right-click on the blank area of the desktop, click Properties, then click the Desktop tab, then click the Customize Desktop button. Click OK to exit.

If you cannot see My Computer on your Start menu, right-click the Start button, click Properties, click the Start Menu tab, click the Customize button. Another dialog window shows. On this window, click the Advanced tab. In the middle part about Start menu items, scroll down to find My Computer, then choose either Display as a link, or Display as a menu. Click OK to exit.

UniPrint license

All UniPrint products are available for free download. When you download any of these products, they are fully functional except that there is a banner / watermark printed diagonally across the printout. (The only exception is UniPrint client software, which is a complementary product to the core products.)

You can request a temporary license that expires in a predetermined date, usually within 30 or 60 days. With the temporary license, you can evaluate the UniPrint product of your interest, and it behaves exactly the same as the fully licensed version. When you are ready to order, you need to call a reseller or a distributor to get a license key.

The steps in applying a temporary license for evaluation is the same as applying a regular license. You will receive in email, as attachment, a license key in the form of a text file with file extension .txt. You will have to rename the extension to a .reg registry file. Some email server or client programs are very vigilant about receiving .reg file as attachments that they may strip off the attachment altogether. That is why the license key file will be sent as plain text file, and you’ll have to rename it back to .reg file.

You need to save the renamed .reg file onto the machine where UniPrint Server is installed. Then you just need to double-click the file to put the license in place.

This applies to the Server-based Computing (SbC) core products up to and including version 6.1.5. Licensing for other products will be discussed in another article.

Why do you need to reboot after installing UniPrint Server?

After you install UniPrint Server, you need to reboot the system in order for it to take effect. But you don’t need to restart the system with Spool Server or Print Server. Why?

When you connect to the UniPrint Server through a remote session, for example, through Microsoft Terminal Services (MS TS) RDP or Citrix ICA connections, the UniPrint program LogScript (LogScrpt.exe) has to be launched to establish virtual channel.

When MS TS starts, it automatically launches all programs listed in the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\Wds\rdpwd\StartupPrograms

The regkey StartupPrograms contains startup programs separated by commas. There should be at least one program there, and it’s rdpclip. After installing UniPrint Server, it should also contain LogScrpt.

The program rdpclip.exe is a Microsoft program used by TS. This program resides in %windir%\System32 (usually it’s C:\WINDOWS\System32), so it should not be a problem for Windows to find this program.

On the other hand, the LogScript program (LogScrpt.exe) resides usually in C:\Program Files\UniPrint Suite\Common Files. But how does Windows know where to find it?

One of the ways that Windows finds a program is to look at the environment variable PATH in the system table, which contains a list of paths for finding programs separated by semi-colons. A typical PATH, after installing UniPrint Server, may look like this:
C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\Program Files\UniPrint Suite\Common Files

Since PATH is a system level environment variable, its content is set only at system startup. Any changes to its content after system startup won’t take effect. For the changes to take effect, one has to simply reboot the machine.

UniPrint products overview

With the current buzzword of Virtual Desktop Infrastructure (VDI), or in the more arcane IT vocabulary of Server-based Computing (SbC), you won't miss this keyword: UniPrint. Why? Simply because they are a key player.

Their products enhance VDI printing and SbC printing in Citrix as well as Microsoft terminal Server platforms. Their products are indispensable in helping system administrators manage and solve printing problems.

The following are their product offerings:

• UniPrint Server – A core product of UniPrint for fat-client printing. A special version, UniPrint Terminal Server Edition, works specifically in the Microsoft Terminal Server platform, but not in the Citrix platform.


• UniPrint Gateway Edition – The core product with extended capability for thin-client printing. There is also a special version, UniPrint Gateway Terminal Server Edition, that works specifically in the Microsoft Terminal Server platform, but not in the Citrix platform.


• UniPrint VDI Edition – This product tailors specifically for printing in a Virtual Desktop Infrasturcture (VDI) environment such as that offered by VMware.


• UniPrint Host Edition – This product enables flexible printing from non-Windows host systems (e.g., mainframes and legacy systems as well as Unix boxes) to Windows desktops.
