Here is the Answer Down,
Scroll down see the steps and do it.....
Since you’re reading this post, the answer to this question is probably yes. I’m not sure about you, but many simply feel that re-installing Windows at regular intervals – after a year, let’s say – keeps the system in optimal state. I wouldn’t argue with that theory, but in such a case, having a reference date of your last Windows installation does make sense. Or you might want to know about the date and time of your Windows installation just out of curiosity. Fortunately, then there are several different ways available to do that, which I will explain step by step, right after the break.
Under the Properties sheet of the Windows directory, you will be able to see it’s Created date and time. This date and time should be the same as when Windows was installed to your computer.
Earlier, I mentioned that this method may not be very accurate, and the reason for this is because since Windows Vista, many computers come with image-based installation media for Windows installation, which doesn’t exactly ‘install’ a new copy of Windows to the machine, but instead just replicates the image on the CD or DVD to the computer’s storage. As the date of actual creation of the Windows folder on the image-based installation media is not the same as the date and time at which you last used that media to reinstall Windows on your computer, the date will not be accurate. To cope with this issue, you can alternatively check the creation date of your ‘Users’ folder because this folder is created during Windows installation. Do note that this will give the accurate result only for the account that was created during or immediately after the installation.
Next, type the following command in the Command Prompt window, and press the Enter key:
The tool will scan the information for youand show you your Windows installation date, as shown below.
The third method is to use the Windows Management Instrumentation Command-line (WMIC). This method is also quite easy and displays accurate result.
First off, open Command Prompt as Administrator and run the following command. You can also refer to the screenshot below:
From the above screenshot, you can see that it displays a number. This number contains year, month,, date, hour, minutes and seconds of the installation date and time. According to the above screenshot, the number translates to 2012-11-05, 10:52:26
The Registry Editor is another way of finding installation time and date on your system. This method is a bit more complex than the ones explained earlier, and require doing some manual calculation. Nevertheless, here’s how to do it.
Open Registry Editor via the Run dialog window or Start Screen.
Now go to the following registry location:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
In the right pane that displays DWORD values, there will be an InstallDate DWORD. It carries the total number of seconds since 1st January, 1970 till the installation time, enclosed in brackets.
There can be a lot of ways you can use this number to calculate the accurate time. One way is to divide this number by 60, 60 and 24 to get the number of days between 1970 and the installation time, and then convert them to years by dividing with 365.25 (to account for leap years). There can be other ways too, including online converters that can calculate this duration for you automatically to show you the correct date and time.

Windows Explorer Method
The first method comprises of taking help from Windows Explorer, and it’s surely the easiest (though not necessarily the most accurate) way of finding out the installation date and time. To do that, simply open the partition where the operating system is installed (usually drive C:) and right-click the ‘Windows’ folder followed by clicking ‘Properties’.Under the Properties sheet of the Windows directory, you will be able to see it’s Created date and time. This date and time should be the same as when Windows was installed to your computer.

System Info Command Method
Another way of finding the correct Windows installation date and time is via the systeminfo command. Just open Command Prompt from your Start Screen or Start Menu.Next, type the following command in the Command Prompt window, and press the Enter key:
systeminfo | find /i "date"The tool will scan the information for youand show you your Windows installation date, as shown below.
WMIC Command Method
The third method is to use the Windows Management Instrumentation Command-line (WMIC). This method is also quite easy and displays accurate result.
First off, open Command Prompt as Administrator and run the following command. You can also refer to the screenshot below:
