Fix: “Print driver host for 32bit applications has stopped working” Error in Windows 7

One problem I’ve experienced when using my Windows 7 64-bit computer with networked printers is that I intermittently get the error:

Print driver host for 32bit applications has stopped working

It appears that this problem occurs for most people when printing to network printers, but I was seeing it even when not printing (I would wake my computer from sleep and the message would already be on my screen).

After doing some research, I discovered that this problem seems to be a flaw in Windows.  Apparently, Microsoft did not include a full list of printer drivers on the OEM installation CD, so some printers get installed incorrectly and cause your system to throw this error.

The Fix

Step 1: First off, you need to uninstall any printers that you have on your computer.  Click Start –> Devices and Printers, locate your printer, right click it, and select Remove device.

Step 2: Now you’ll need to reinstall the printer as a locally attached network printer (don’t worry, it will work just the same as before).  To do this, click the Add a printer button in the Devices and Printers window from the previous step.

In the resulting window, select Add a local printer.

Then click the option for Create a new port and select Standard TCP/IP Port from the dropdown menu.

Step 3: Type in the networked printer’s hostname or IP address.  The port name will automatically fill itself in with the same information.  Be sure to leave the Query the printer and automatically select the driver to use box unchecked, then click Next.

Step 4: Click the Windows Update button to retrieve an updated list of printer drivers from Microsoft.  Locate your printer in this list and proceed with the installation – this should fix your problem.

If you continue to experience problems with the print driver host for 32-bit applications crashing, try downloading the driver from the printer’s manufacturer and using that in Step 4 by selecting the Have Disk option.

Fix: Windows XP Gets Blue Screen Error after Windows Update (KB977165)

A recent Windows Update (KB977165) for Windows XP caused many computers to experience Blue Screen of Death (BSOD) errors when the computer restarted after the update.  The cause of the blue screen wasn’t just the update, but rather a rootkit (a form of malware) which had been present on the users’ machines prior to the update.

The specific error is:

PAGE_FAULT_IN_NONPAGED_AREA

Technical Information:

STOP: 0x00000050 (0x80097004, 0x00000001, 0x80515103, 0x00000000).

This guide will help you get your computer back into a bootable state and get rid of the rootkit. To do this, you will need a Windows XP installation disc in order to access the repair options.

Step 1: Insert the Windows XP disc and restart your computer.  When the computer initially starts, you should see “Press any key to boot from CD” message which you must do.  If you do not see this message, you may need to configure your computer to boot from the CD drive.

When the content on the CD has finished loading, you should be presented with a screen that looks like this:

Step 2: Press the ‘R’ key to access the recovery console. You should now be presented with what looks like a DOS prompt.

You may see multiple options when asked which installation you would like to log into. The one you want should look something like the one in the picture, “C:\WINDOWS”. Enter the password for the Administrator account when prompted. If you haven’t set up a password for the Administrator account, just press Enter.

Step 3: Enter the following command (since Windows isn’t case sensitive, you don’t need to worry about any capital letters):

chdir $ntuninstallkb977165$\spuninst

and press Enter.

Now enter the command:

batch spuninst.txt

and press Enter

Once that procedure has finished, type ‘exit‘ and press Enter to restart your computer, and don’t forget to remove the CD.  When your computer restarts it should be able to boot into Windows. We now need to perform a few final steps to remove the rootkit.

Removing the Rootkit

First we need to download and install Microsoft Security Essentials. Once it is installed, it should update itself automatically with the latest virus definitions. From the ‘Home’ tab, set the radio button to ‘Quick’ and press ‘Scan now’.

The scan might take anywhere from 10-20 minutes (or more if you’re on a particularly slow computer). Once it has finished scanning, it will present you with the option to clean up any items it found. Go ahead and do this, after which you may be asked to restart your computer.

It should now be safe to run Windows Update again, since Microsoft Security Essentials takes care of the virus that caused the problem.

Since there’s probably other malware residing on your system, it would be a good idea to install and run Malwarebytes as well, just in case. Also, make sure you’re running an antivirus program and that it’s up to date.

Fix: Windows Vista 64-bit Gets Blue Screen After Windows Updates

A recent Windows Update (KB973879) has been causing a “blue screen of death” (stop error) in many computers running Windows Vista 64-bit edition.  Many of the affected computers are HP Pavillion dv Series laptops (such as dv4 and dv6 models), but we have had reports of other manufactures having the same issues.  The problem occurs shortly after starting the computer.

The specific error is:
