Find The Microsoft.NET Framework Version Installed In Your Windows PC

April 13, 2010April 13, 2010 by bharath

Microsoft .Net logo

Well, if you are using a computer running Windows operating system, you might be aware of the Microsoft .NET Framework that needs to be installed in your computer in order to let the most newer applications created for Windows run smoothly on your PC without much compatibility issues.

While it’s easier to install the .NET Framework SDK anytime by downloading the file from the Microsoft’s website, you may definitely want to know the version of the .NET Framework installed on your Windows based computer.

So here I’m trying to guide you through the various ways in which you can find the .NET version installed on your computer.

Method 1 : Using Registry Editor:

If you are familiar with Windows registry editor (by using regedit command), this should be the easier way to find the version of .NET installed.You just have to navigate to the following registry path and check the value present for the key entry “Version” (which is 3.5.30729… in my case) as shown below.

Path: HKEY_LOCAL_MACHINE\ SOFTWARE\ MICROSOFT\ NET Framework Setup\ NDP\ v3.5

Method 2: Using IE User Agent String

Please note that this method works only with Internet explorer.

Here we are querying the user agent string of Internet Explorer.Copy the following JavaScript in to your Internet Explorer address bar and press enter, you will now see an alert something similar to the one shown below.

javascript:alert(navigator.userAgent)

User Agent String Javascript

As shown above, querying the IE User Agent String has resulted in a pop-up alert that shows all the .NET versions installed on my Windows 7 machine (.NET 2.0.50727, .NET 3.0.30729 & the latest one being .NET CLR 3.5.30729).

Even though other browsers like Mozilla Firefox, Google Chrome & Opera also respond to the user Agent String query, they will not however show the actual versions of .NET Framework installed.

Method 3: Using Add or Remove Windows Programs/ Features

If you are using Windows XP and earlier operating systems, just go to control panel and click “Add or Remove Programs” find the version of .NET Framework in the programs installed.

If you are using Windows 7 or Windows Vista, go to Control Panel > Programs> Turn Windows features on or off, find “Microsoft .NET Framework” in the list and note down the version number.

Windows features .Net Framework

Method 4: Using Aaron Stebner .NET Framework Detector Code

If you are a programming geek and want to detect the version of .NET Framework installed on your PC with a simple C++ code, you may want to check Aaron Stebner’s .NET Framework checker code(cpp) which you can run using your Visual Studio/Visual C++ 2005 or 2007 versions.

Method 5 : Using Windows Explorer

To see which versions of the .NET Framework are installed on your PC, locate the %systemroot%\Microsoft.NET\Framework folder by typing the same in the Windows explorer address bar you sill something like this :

v3.5
v3.0
v2.0.50727
v1.1.4322
v1.0.3705

.NET Framework folder windows These represent the versions of the .NET Framework installed in your computer.

This problem is very common. May be after reboot it may work again, but for some systems the tray may never come up. This tray will hide the inactive and unnecessary icons from the taskbar. So many people like this feature. Making it work again is what we are talking about here.

Change MAC Address or Physical Address Using Registry Editor (regedit) in Windows

April 6, 2009March 28, 2009 by dennis

Many people have a wrong conception that changing MAC Address of a computer is not possible or it requires a complex software. But it is not true. Changing MAC or Physical address of your computer is very simple. MAC (Media Access Control) address, Ethernet Hardware Address (EHA), hardware address, adapter address or physical address is a quasi-unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification. If assigned by the manufacturer, a MAC address usually encodes the manufacturer’s registered identification number. Although intended to be a permanent and globally unique identification, it is possible to change the MAC address on most of today’s hardware, an action often referred to as MAC spoofing.

Now getting to the point we can change MAC by using your Windows Registry Editor. The method has been successfully tested in different Wired Ethernet Adapters, Wireless Adapters etc.

Follow the steps below and your MAC will be changed in seconds:

Step 1: Open Registry Editor (Press Start + R, Type regedit and Enter). If you get a message like “Your Registry Editor Has Been Disabled By Your Administrator” then you need to enable it. To Enable Registry Editor Visit: How to enable registry Editor

Step 2: After opening Registry Editor successfully, see the left pane of your registry editor. You can find a series of registry keys. You have to follow the path as:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{4D36E972-E325-xxxx}

For the last key search for the red highlighted part in your Editor. You can refer the image below:

Step 3: After opening the last Key you will see a set of keys like 0000, 0001, 0002 etc. You have to open each key and search for values which corresponds to your network adapter. For example, I have an Intel(R) PRO/100 VE Network Connection. So in the right side of the editor i found a value which is containing this name. This is how we identify the key for the network adapter. For me i got the key in 0007.

Step 4: Now search for the value NetworkAddress inside the key you have found. If you cant find it right click and create a new String Value of the name NetworkAddress.
