May have planned a Reinstalare de Windows And you are curious how long it has been from the last. Or you may want to find out how long it has been since you last installed WinXP To decide whether or not to do a reinstallation. In any of these two cases (or for any other reason) you can follow one of Methods below to Find out the exact date and time when Windows last was installed on one computer.
How do we find out when Windows was last installed?
1. The first method would be to use Windows Explorer. While many users would believe that the date on which any one was created folder Of the ones system (Program Files, ProgramData, Users, Windows etc.) coincides with The date on which the operating system was installed, starting with Windows Vista is no longer the case (practically the folders are copied from Installation image, and the date of property to these will be the date on which the image from which Windows was installed was created). Instead the date on which a particular System Folder it is and the date of installation of the system, namely the user's folder created during installation.
2. The second method (as the third) involves the use Command prompt. Open one Command Prompt with Administrator Privileges And then type the following command:
systeminfo | find /i “date”
3. Into Command Prompt (All with Administrator privileges) Tab the following command:
WMIC OS GET installdate
The number displayed indicates the year, luna, day and ora exact to which Windows was installed (including minutes and seconds); In this case 2013-07-18 11:06:31.
4. And the fourth method, a little more complex than the other 3, involves Registry Editor. open regedit you navigate catre HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersion. In the left panel identify the entrance InstallDate.
Its value is equal to the number of seconds that have passed from January 1, 1970 Until the date on which the system was installed (divide the number at 60, once again 60 then to 24 to find out how many days they passed between the two data; Then the number of days divide it to 365.25 to find out the number of years etc., or you can use a converter online for an automatic calculation such as Time Converter).
