[TipJar] High and Snipe

No Comments

At work, the Windows 7 workstation we were given came with a Trojan-esque gift: several instances of wscript.exe are running at startup and uses all available CPU processing cycles. Killing them off does not show any adverse effects (yet) but the graphical way is a bit time consuming as the machine is already slow at this point.

Below is the quickest way to snipe these instances using the lowest memory-guzzler tool in every Windows arsenal: the command line processor window. The only catch is that the wscript instances would require the kill command to be executed from an elevated command prompt as the Windows User Access Control (UAC) is active.
1. Press the Window key to bring up the startup menu.
2. In the Start menu search box, type “cmd”. The first entry highlighted is the program entry.

elevated cli

3. Press “Ctrl+Shift+Enter” to run the command in elevated mode. If UAC is really running, a confirmation prompt will be displayed for the command line processor.

elevated cli

4. Invoke the command “taskkill /im wscript.exe /f ” to kill all running instances of wscript.exe.

5. To validate if there are still instances running, run the command “tasklist | find “wscript” ” (omit the first and last double quotes). Nothing should be shown.

The exercise above can be adapted to quickly kill some errant processes without going through the task manager or resource monitor GUI clients. Be careful in what you kill for it might bite back. 🙂

[UPDATE] A colleague,Ron Emil Castro, has provided this trick on combining both in a script that will load up with administrator privileges upon startup for Vista/Win7 machines.

  • Create a batch script with the following code

CHOICE /N /C YN /T 15 /D Y
taskkill /im wscript.exe /f

The first command waits for 15 seconds to give the script enough time to run and the second kills it as specified in the script above.

  • Open the startup folder by right-clicking on the Start->All Programs->Startup item then selecting the Open option.
  • Create a shortcut to the batch script. Right-click on the shortcut and open the properties window. Select the “Run as Administrator” option under the Advanced section.

[UPDATE] The processes are because of an errant firewall checker script loaded by the domain policies. The alternate solution provided by the support team is to execute the C:\Windows\system32\wscript.exe binary and set the timeout to a low number (5 or 10 seconds). Use the recommendation at your own risk as this basically handicaps the execution of other scripts that would require more time than the set timeout.

If you want to minimize the amount of electricity used by your computer but dislike shutting down your computer because of the amount of time it need to start it up and open your applications, there is a compromise to be had if your operating system is configured properly to hibernate.

Hibernating an operating system means that all the information in the system memory (RAM to be precise) is written down as a “snapshot image” to the hard disk. The PC hardware is then turned off since the hard disk will not lose its information when powered down. When the machine is turned back on, the booting process of the operating system will look for a store snapshot image and load it back into the system memory. If this is successful, you will have your desktop at the same state as when it was hibernated. The time it needs to resume a hibernated image is relatively small compared to when booting the operating system from scratch (or what is called a cold boot).
All modern operating systems have support for hibernation but not all are enabled by default. To following steps will enable this feature in Windows XP:

  1. Go to Start->Control Panel->Power Options.
  2. Go to the “Hibernate” tab and ensure that the “Enable hibernation” check box is ticked. Click OK to dismiss the dialog and apply the change.
    WARNING: This will reserve space on the system drive equal to the amount of RAM in your computer. If you have 2GB of RAM, 2GB of hard disk space will be set aside for hibernation.
  3. To hibernate, shutdown the machine but select the hibernate option. The machine will be turned off automatically (if this is properly configured).
  4. To resume the hibernated image, turn on the machine. The image will be invalidated after a successful resume.

NOTES:
– Some applications, usually those that have time-bound login sessions, do not like being hibernated.
– The space set aside for the hibernation support is different with the space allocated for the virtual memory.
– If the machine fails to resume or hangs while in the process of resuming, reboot the machine and boot into safe mode (Press F8 after the BIOS screens). Reboot the machine to invalidate the hibernate images and the machine should boot normally after.

[TipJar] Office Copycat

MS Office provides a helpful function in ensuring that style consistency is easily done on the documents being created. The function is called the “Format Painter” which is part of the Standard toolbar.

If the icon is not visible (if not previously used) it can be added from the toolbar dropdown which is located at the end of the toolbar section.

How to use the Format painter:

  1. Highlight the text (or cells in spreadsheets) containing the style that you want to copy.
  2. Click on the “Format Painter” icon to copy the style into the painter memory.
  3. Highlight the text (or cell) that you want to have the same format.

Format Painter loses its “memory” after every cycle so repeat steps 1-3 as you see fit. Styles can also be used in Word documents to facilitate the document formatting process.

[TipJar] Removing zip integration from Windows Explorer

No Comments

Zip integration was introduced starting Windows XP which enables the Windows Explorer to treat zip archives as a normal directory. This allows users to visit the content structure of the archive without depending on an external application like Winzip or extracting the content.

The downside of this integration is that Windows Explorer needs to finish reading all of the zip archives in the directory being visited before the directory contents are listed. This can cause a significant performance slowdown if there are many or huge zip files in the directory.

To disable the zip integration, the following command can be invoked (requires admin privileges):

regsvr32 /u zipfldr

The command above will clear all zip file associations. If you have Winzip installed, launch a new instance and Winzip will prompt if you want to restore the association. Select the ‘Yes‘ option otherwise zip archives will not be handled properly when double-clicked from Windows Explorer.

If another archiver utility is used, look around the preference page for the association options if the prompt doesnt show at the startup of the the utility.

NOTES:

  • If Winzip was configured to not show the prompt above, the associations can be done from the Tools->Configuration->System menu.
  • If you are using a different application for handling archives (e.g. WinRar, 7zip, etc.), explore it’s configuration window or refer to the manual.
  • The command “regsvr32 zipfldr” will restore the zip integration of Windows Explorer.
  • BONUS: Dump Winzip and switch to 7zip. It supports more archive types, achieves significantly better compression, and best of all it is Open Source and free!
