You may sometimes think of reinstalling Windows, especially when its performance goes down after a few years due to several different factors. And, you may like to know the date and time of your current Windows installation.<\/p>\n

This post shows you the different methods using which you can determine the original installation date and time of your Windows installation. The information applies to all versions of Windows, including Windows 10.<\/p>\n

Note that in Windows 10, the following methods show the installation date of the most recent feature update you installed, and not the install date and time of your 1st Windows 10 build.<\/p>\n

<\/p>\n

RELATED:<\/strong> Find the Windows 10 Build\/Version Upgrade History on your computer<\/a><\/div>\n
\n

Find the Windows installation date\/time:<\/h4>\n
    \n
  1. Use the systeminfo command<\/a><\/li>\n
  2. Using the System Settings page<\/a><\/li>\n
  3. Using VBScript<\/a><\/li>\n
  4. Using WMIC command-line<\/a><\/li>\n
  5. Using PowerShell<\/a><\/li>\n
  6. Using Windows registry<\/a><\/li>\n
  7. Using Windows registry #2<\/a> (another interesting location)<\/li>\n<\/ol>\n<\/div>\n

    How to Find Windows Installation Date and Time<\/h2>\n

    <\/a>1. Using SystemInfo<\/h3>\n

    Open a Command Prompt window and type:<\/p>\n

    systeminfo<\/pre>\n
    \"systeminfo<\/p>\n
    To output only the Original Install Date field, type:<\/p>\n
    systeminfo | findstr Date<\/pre>\n
    <\/a>2. Settings page in Windows 10<\/h3>\n
    The Settings page shows the Windows installation date in Windows 10.<\/p>\n
    Click Start \u2192 Settings \u2192 System \u2192 About.<\/p>\n
    Scroll down to Windows specifications to find the Windows install date.<\/p>\n
    \"settings
    Screenshot of the settings page in Windows 10 v20H2<\/figcaption><\/figure>\n
    <\/a>3. Using WMI\/WSH Script<\/h3>\n
    Copy the following VBScript code to Notepad, save with .vbs<\/code> extension in ANSI<\/code><\/strong> encoding, and run the file.<\/p>\n
    Set\u2002dtmInstallDate\u2002=\u2002CreateObject(\u2002_\r\n\"WbemScripting.SWbemDateTime\")\r\nSet\u2002objWMIService\u2002=\u2002GetObject(\"winmgmts:\"\u2002_\r\n&\u2002\"{impersonationLevel=impersonate}!\\\\\"\u2002_\r\n&\u2002\".\"\u2002&\u2002\"\\root\\cimv2\")\r\nSet\u2002colOperatingSystems\u2002=\u2002objWMIService.ExecQuery\u2002_\r\n(\"Select\u2002*\u2002from\u2002Win32_OperatingSystem\")\r\nFor\u2002Each\u2002objOS\u2002In\u2002colOperatingSystems\r\n\u2002\u2002\u2002MsgBox\u2002\"Install\u2002Date:\u2002\"\u2002&\u2002getdate\u2002(objOS.InstallDate),\u2002_\r\n\u2002\u2002\u2002vbOKOnly,\u2002\"OS\u2002Install\u2002Date\"\r\n\u2002\u2002\u2002\r\nNext\r\n\r\nFunction\u2002getdate(wmitime)\r\n\u2002\u2002\u2002dtmInstallDate.Value\u2002=\u2002wmitime\r\n\u2002\u2002\u2002getdate\u2002=\u2002dtmInstallDate.GetVarDate\r\nEnd\u2002Function\r\n<\/pre>\n
    \"vbscript<\/p>\n
    <\/a>4. Using WMIC (WMI command-line)<\/h3>\n
    wmic os get installdate<\/pre>\n
    \"systeminfo<\/p>\n
    The date\/time stamp is shown in the following WMI time format<\/a>:<\/p>\n
    yyyymmddHHMMSS<\/i><\/pre>\n
    ..which translates to:<\/p>\n
    29\/05\/2020, 11:38:49<\/pre>\n
    <\/a>5. Using PowerShell<\/h3>\n
    This again uses WMI, but the only difference is it’s run from PowerShell and uses PowerShell’s built-in ConvertToDateTime<\/i> function.<\/p>\n
    ([WMI]'').ConvertToDateTime((Get-WmiObject Win32_OperatingSystem).InstallDate)<\/pre>\n
    \"powershell<\/p>\n
    <\/a>5. Using the Windows Registry<\/h3>\n
    The Windows installation date and time is stored in the following registry key in the values named InstallDate<\/strong> and InstallTime<\/strong>:<\/p>\n
    HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\InstallDate<\/pre>\n
    \"registry<\/p>\n
    The InstallDate<\/code> value data contains the Unix time which represents the number of seconds that have elapsed since 1970-01-01T00:00:00Z (January 1, 1970, at 12:00 AM UTC).\u00a0\u00a0To convert the data into a readable format, you can the Epoch converter website or run a couple of PowerShell commands.<\/p>\n
    via Epoch Converter site<\/strong><\/p>\n
    Visit the Epoch converter<\/a>\u00a0website and type the timestamp you found in the registry, and convert it to human date format.<\/p>\n
    \"epoch
    Convert Unix time to readable date\/time<\/figcaption><\/figure>\n
    Using PowerShell<\/strong><\/p>\n
    In the PowerShell window, run these two commands:<\/p>\n
    $date = Get-ItemProperty -Path 'HKLM:\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\' | select -ExpandProperty InstallDate\r\n\r\n(Get-Date \"1970-01-01 00:00:00.000Z\") + ([TimeSpan]::FromSeconds($date))<\/pre>\n
    \"powershell<\/p>\n
    The above shows the date and time of the current Windows 10 feature update (v20H2) installation.<\/p>\n
    \n
    <\/a>Windows 10\/11 Build\/Version Upgrade History<\/h3>\n
    Did you know that Windows 10\/11 keeps track<\/a> of your every build\/feature upgrade in the registry? Redditor u\/sizzlr<\/a> has found an interesting registry location and wrote a PowerShell script to unscramble the Windows 10\/11 build installation dates from the registry.<\/p>\n
    Every time you install a feature update, Windows 10\/11 creates a new subkey named “Source OS (Updated on )” and a bunch of values in the right pane. The registry key is located at:<\/p>\n
    HKEY_LOCAL_MACHINE\\SYSTEM\\Setup<\/pre>\n
    \"\"<\/p>\n
    Additionally, there are two values, namely InstallTime and InstallDate, which store the install date and time. The following PowerShell script gathers all the details for you and presents in a table:<\/p>\n
    $AllBuilds = $(gci \"HKLM:\\System\\Setup\" | ? {$_.Name -match \"\\\\Source\\s\"}) | % { $_ | Select @{n=\"UpdateTime\";e={if ($_.Name -match \"Updated\\son\\s(\\d{1,2}\\\/\\d{1,2}\\\/\\d{4}\\s\\d{2}:\\d{2}:\\d{2})\\)$\") {[dateTime]::Parse($Matches[1],([Globalization.CultureInfo]::CreateSpecificCulture('en-US')))}}}, @{n=\"ReleaseID\";e={$_.GetValue(\"ReleaseID\")}},@{n=\"Branch\";e={$_.GetValue(\"BuildBranch\")}},@{n=\"Build\";e={$_.GetValue(\"CurrentBuild\")}},@{n=\"ProductName\";e={$_.GetValue(\"ProductName\")}},@{n=\"InstallTime\";e={[datetime]::FromFileTime($_.GetValue(\"InstallTime\"))}} };\r\n\r\n$AllBuilds | Sort UpdateTime | ft UpdateTime, ReleaseID, Branch, Build, ProductName\r\n<\/pre>\n
    \"\"<\/p>\n
    The installation date for each build\/version is maintained in the registry.<\/p>\n
