GoLang Windows API Wrappers

For System Info / User Management.

For an internal project, this is a set of wrappers for snippets of the Windows API.

Tested and developed for Windows 10 x64.

All functions that return useful data, do so in the form of JSON exportable structs.

These structs are available in the shared library, "github.com/iamacarpet/go-win64api/v2/shared"

Process List

package main

import (
    "fmt"
    wapi "github.com/iamacarpet/go-win64api/v2"
)

func main(){
    pr, err := wapi.ProcessList()
    if err != nil {
        fmt.Printf("Error fetching process list... %s\r\n", err.Error())
    }
    for _, p := range pr {
        fmt.Printf("%8d - %-30s - %-30s - %s\r\n", p.Pid, p.Username, p.Executable, p.Fullpath)
    }
}

Active Session List (Logged in users + Run-As users)

package main

import (
    "fmt"
    wapi "github.com/iamacarpet/go-win64api/v2"
)

func main(){
    // This check runs best as NT AUTHORITY\SYSTEM
    //
    // Running as a normal or even elevated user,
    // we can't properly detect who is an admin or not.
    //
    // This is because we require TOKEN_DUPLICATE permission,
    // which we don't seem to have otherwise (Win10).
    users, err := wapi.ListLoggedInUsers()
    if err != nil {
        fmt.Printf("Error fetching user session list.\r\n")
        return
    }

    fmt.Printf("Users currently logged in (Admin check doesn't work for AD Accounts):\r\n")
    for _, u := range users {
        fmt.Printf("\t%-50s - Local User: %-5t - Local Admin: %t\r\n", u.FullUser(), u.LocalUser, u.LocalAdmin)
    }
}

Installed Software List

package main

import (
    "fmt"
    wapi "github.com/iamacarpet/go-win64api/v2"
)

func main(){
    sw, err := wapi.InstalledSoftwareList()
    if err != nil {
        fmt.Printf("%s\r\n", err.Error())
    }

    for _, s := range sw {
        fmt.Printf("%-100s - %s - %s\r\n", s.Name(), s.Architecture(), s.Version())
    }
}

Windows Update Status

package main

import (

func main() {
        ret, err := wapi.UpdatesPending()
        if err != nil {
                fmt.Printf("Error fetching data... %s\r\n", err.Error())
        }

        fmt.Printf("Number of Updates Available: %d\n", ret.NumUpdates)
        fmt.Printf("Updates Pending:             %t\n\n", ret.UpdatesReq)
        fmt.Printf("%25s | %25s | %s\n", "EVENT DATE", "STATUS", "UPDATE NAME")
        for _, v := range ret.UpdateHistory {
                fmt.Printf("%25s | %25s | %s\n", v.EventDate.Format(time.RFC822), v.Status, v.UpdateName)
        }
