Google Chrome request UAC at every start, solution

admin — Mon, 10 May 2010 20:32:40 +0000

Suddenly at start of Google Chrome (installed month’s ago) Windows 7 show the request UAC (User Access Control), indicating that this program will try to start with administrator rights. Probably due to update of Chrome or more likely one of his plugin, must have changed some parameters and Windows, rightly, he notice me a possible danger like a virus or trojan. Knowing that the version installed (and reinstalled for safety) is healthy, I tried a quick workaround. First I found the executable, which usually is not in the classic c:\Program Files but under your user account:

C:\Users\YOURUSERNAME\AppData\Local\Google\Chrome\Application\chrome.exe

So “classic” right click chrome.exe property. From the screen that comes out press on compatibility and then at the bottom you will find the button “change settings for all users“.
A new window appears, after all, de-select option “start this program as administrator“.
Give OK to close all windows, and the problem is finally solved.

VPN Checkpoint SSL Extender and Windows 7

admin — Mon, 21 Dec 2009 21:50:59 +0000

If you have a version of “old” Checkpoint, from R71 and before, with a license Extender SSL (clientless VPN over port 443) certainly will not work under Windows Vista and Windows 7. The Java client (or ActiveX) will return an error “failed to load”. The problem has been confirmed by Checkpoint itself.

The solution for the new Windows operating systems (excluding XP family) is to download a small application called SNEX that actually goes to update that installed from the web page SSL extender.

However is possible (obviously for the sys-admin that manages the property Checkpoint) to update the client SNEX the webserver Checkpoint as documented in this page.

Make a bootable USB key

Today we had the need to “burn” (of course the correct term is “load”) an ISO image on a bootable USB stick. The problem was how to transfer a previously ISO image on a USB key and make it bootable. We found this very interesting project on sourceforge, named UNetbootin.

This small program in Windows version ( installation is not required) and Linux too, allow to create a bootable stick with an single easy step.

Outlook 2003 show wrong date on incoming mails

admin — Thu, 03 Sep 2009 09:13:18 +0000

I found a user who had a curious problem, the incoming mail had the wrong time, in practice was an hour behind. Nothing serious, but it was annoying. Obviously occurred after the clock on his computer and one where he resides on the Exchange server was not wrong, I narrowed the field to the Outlook 2003 client, since it was the only one with this situation. Among the forest of options in fact there is one that allows you to manipulate not only the date of mail, but also on the calendar. Obviously this option is not under the section E-Mail ….

So if you have this problem, the solution is to look under the menu in Outlook 2003 under Tools -> Options -> (Preferences tab) Calendar Options -> Time Zone

The window is activated, although under the heading calendar allows you to change the time zone, or as in my case, to turn on “daylight saving.”

Remove Mozilla Firefox extensions

admin — Thu, 20 Aug 2009 19:49:49 +0000

Recently, after some upgrades of Mozilla Firefox, i have found some extensions disabled because no longer compatible with the new version of the browser. In particular I refer to “2 pc sync syncronization” extension of Nokia PC Suite amd Framework 3.5 Microsoft extension. This extensions, in my opinion, are unnecessary especially because is installed their own during a setup.

The problem of that extension is in fact are already been disabled, because no longer compatible, but remains in the extension list until to an update, where can be automatically reinstalled. This situation seems irreversible because the “uninstall” button is no longer activated. If you wish you can delete them with a little surgery on the registry of your Windows. So follow the instructions at your own risk.

Open Regedit (start -> run -> regedit [return])
navigate in your left until you find the entry:
HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Firefox\extensions
First we prepared a good backup of this key, right mouse button, choose “Export” to save where you like (to restore just a simple double click on the saved file).
Now focus our attention on the right side of Regedit, you should see the entries “locked” in our case it is the voice bkmrksync@nokia.com and just above a path that clearly draws on .NET framework from Microsoft.

We need to eliminate it, with the right button on the item you selected, and then “delete” command.
Start Firefox and “magically” extensions blocked are missing from the list.

Windows 7 change logon UI background

admin — Tue, 31 Mar 2009 14:00:21 +0000

Windows 7 have own Logon UI customizable option. The new operating system support loading images as background for login screen without using third-party software.

Be careful, you have to change something in the Windows Registry, proceed with your own responsability.

Open the registry (start -> run -> regedit or WindowsKey -> regedit)
find the key HKLM\Software\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background
if not present create a new DWORD called OEMBackground with value 1 (0 for disable)
Registry is done, now we must place the backround in right place. The default folder is %windir%\system32\oobe\info\backgrounds
if the directory backgrounds is not present, make new one
put inside the new backrounds, but the are some pre-requisites. The file must less than 256KB. The name of file must be backgroundDefault.jpg. Is good idea make backround at same resolution of your screen, otherwise image will strech-to-fit

happy tweaking
