I recently helped a user with a McAfee VirusScan problem. The On-Access Scanner was turned off and when you tried to turn it on, it would not turn on. The user had just restarted the machine, so restarting the machine again was not an option. I tried to restart the services related to VirusScan, but the services were locked and I could not restart them. This is what I did to enable the On-Access Scanner.
- Open VirusScan Console.
- Click on Access Protection and click on Task -> Properties.
- Uncheck Prevent McAfee services from being stopped and click on OK.
- Open up the services manager. You can do so by pressing Windows key + R, and type services.msc and enter.
- Stop the following services: McAfee Framework Service, McAfee McShield and McAfee Task Manager.
- Start the services mentioned in step 5.
We just found out that, when a HP printer is installed- even if the printer is capable of duplex printing- it may not be enabled for some computers. You will have to manually enable duplex printing. Here is how:
- Click on the printer you want to enable duplex printing in Devices and Printers.
- Click on Customize your printer.
- If you see a button on the left bottom corner that says Change properties, click on it. If you do not see this button, you can skip to the next step.
- Click on Device Settings and find Duplex Unit (for 2-Sided Printing). Change it to Installed.
- If you want to set duplex printing as default, click on General tab and then Preferences …. A new dialog pops up. Click on Finish and then check Print on both sides.
Ever since I upgraded my workstation to Windows 8, I spent most of my time with a desktop and use it like a Windows 7 machine. I rarely use those so-called “Windows Store Apps”. The only app that I use the most often is the Mail app: It allows me to access all my email accounts in one place without going through multiple web sites. However, I recently noticed that the Mail app did not work anymore. I tried several other Windows Store apps and most of them did not work either. The apps just showed spinning circles, and they did not launch at all. I tried to uninstall the Mail app and reinstall it. However, the Store app did not work either! I found a Microsoft article about apps troubleshooting. Their recommendations are to update your app, sync the app license or reinstall the app. They all requires a working Store app to perform. Since my Store app did not work at all, I could not try the recommended steps to solve the problem. At the end of the article, it mentions Apps troubleshooter. It’s an application that can try to fix problems related to Windows Store apps. I tried to run the Apps troubleshooter twice. It found different problems each time. This looked promising, but it did not fix my problem.
I then searched for other solutions. I came across one article that mentioned how uninstalling anti-virus software might help. I had McAfee Enterprise 8.8 with patch 3 installed in my computer, so I tried uninstalling it. After McAfee was uninstalled, the apps started to run again! If all else fails, you might try this to get uncooperative apps to launch again.
When I first installed Windows 8 on Virtual PC, I ran into a problem: the Guest Additions were not compatible with Windows 8. I had to use Recovery mode to refresh my Windows 8 installation. The Recovery mode was automatically invoked after I failed to boot the virtual machine up several times. I tried the Guest Additions today, thinking that it would be compatible with Windows 8 after a few months passed. It turned out that the Guest Additions were still not compatible with Windows 8. I ran into the same problem again; the virtual machine booted up to a black screen. I tried to reboot the virtual machine several times, hoping that it would invoke Recovery Mode for me to uninstall the Guest Additions. However, the Recovery Mode did not run automatically this time. I found a trick to force the Windows 8 virtual machine to boot to Recovery Mode. All you have to do is to disable the network adapter. Here are the steps:
- Select the Windows 8 virtual machine and click on Settings.
- Click on Network and make sure Enable Network Adapter is not checked for all 4 adapters.
- Start the virtual machine and it will enter Recovery Mode.
I was working on an Excel spreadsheet this afternoon. I needed to create a new spreadsheet and keep the current one open. For some reason, after I created a new file, I can not view the original file that I worked on. I tried to close every file and re-open the original file, it did not help. I first thought the workbook was minimize or hidden, but they were not the cause.
After fiddling around with the menu, I finally got it to show up again. Here is what I did:
- Click on View.
- Click on New Windows.
Afterwards, I was able to see my workbook again.
One user reported that regular users could not run Photoshop on one of our servers, but admin users could. Whenever a regular user tried to run Photoshop, this message popped up.
The application failed to initialize properly (0xc0000022). Click on OK to terminate the application.
The cause for this problem was that the application was installed for the original admin user only. All the files did not have correct permissions for regular users. In order to fix this problem, you’ll need to grant permission to regular users to access these files, including all the *.EXE, *.DLL and *.OCX files. If you use Windows Explorer, you’ll need to do this for all of the files, which is a fairly tedious process. It’s much faster to use commands to do this. Here are the steps.
- Run an elevated command prompt.
- Change directory to the program directory.
- Enter the following command:
cacls *.exe /e /g builtin\users:r
cacls *.dll /e /g builtin\users:r
cacls *.ocx /e /g builtin\users:r
The biggest change of Windows 8 is the Metro interface. While the Metro interface is good for a tablet, it’s not designed for desktop computers. I upgraded my main workstation to Windows 8 a while ago. I use the desktop about 99% of time, and I only use the Metro interface when it’s necessary.
I found that if you have multiple monitors, you can configure it so that Metro only shows on the second monitor. This works very well, and the interface does not interfere with the applications on the main monitor. Here is how to do it.
- Move the cursor to the corner of the second monitor.
- Click on the Start icon.
This activates the Metro interface on the second monitor. From now on, whenever you press the Windows key, the Metro interface will show on the second monitor. Note that this change only applies to the current session. You’ll have to do it again the next time you log on.
