This script will scan through a list of UNC’s and it will locate any folders or files that are older than 90 days. You can change the amount of days by editing the $gtdays variable.

$servers = Get-Content "\\SERVER\"
$gtdays = "90"
$timeformat='yyyy/MM/dd hh:mm:ss tt'
$time = (Get-Date).ToString($timeformat) 
$drive = "v"
$drivemapped = $drive + ":"

$username = 'USERNAME'
$password = ConvertTo-SecureString -string 'PASSWORD' -AsPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential -argumentlist $username, $password

foreach($server in $servers) {
    
    #cmd /c net use v: $server  | Out-Null
    New-PSDrive -name $drive -psprovider filesystem -root $server -Credential $cred  | Out-Null
    $date = Get-ChildItem $drivemapped| Sort-Object -Descending -Property LastWriteTime | Select-Object -First 1
    $days = (New-TimeSpan $date.LastWriteTime $time).Days
    #cmd /c net use v: "/delete" | Out-Null
    Remove-PSDrive $drive | Out-Null

    if($days -gt $gtdays) {
        New-Object –TypeName PSObject -Property @{
            'Server' = $server
            'File or Folder Name' = $date.Name
            'Date'= $date.LastWriteTime
            'Days Old'= $days
        }
        
    }
    else {
              
    }   
}

Below is a script that will automatically uninstall and reinstall a 32bit application.

Please note: This script only works with 32bit applications!

In order for this script to work, you will need to configure the following:
$Appname = Insert Application Name
$AppSetup = Insert Application File Path After MSIEXEC /I
$Silent = Insert Silent Install Switches
$SilentUninstall = Insert Silent Uninstall Switches

I am using TightVNC for the following example:

$appname = 'TightVNC'
$32bit = get-itemproperty 'HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*' | Select-Object DisplayName, DisplayVersion, UninstallString, PSChildName | Where-Object { $_.DisplayName -match "^*$appname*"}
$appSetup="msiexec /i tightvnc-2.7.10-setup-64bit.msi"
$silent = " /quiet /norestart ADDLOCAL=Viewer"
$silentuninstall = " /qn"

if ($32bit -eq "" -or $32bit.count -eq 0) {
                Write-Host "Software is not Installed"
                Start-Sleep -s 3
                Clear-Host
                Write-Host "Starting Setup..."
                cmd /c ($appSetup + $silent)
                Clear-Host
                Write-Host "Installation Complete!"
                Start-Sleep -s 3
}
else {
    
                $Uninstallstring = $32bit.UninstallString -replace 'msiexec.exe /i','msiexec.exe /x'
                Write-Host "Uninstalling Software..."
                cmd /c ($uninstallstring + $silentuninstall)
                Clear-Host
                Write-Host "Starting Setup..."
                cmd /c ($appSetup + $silent)
                Clear-Host
                Write-Host "Installation Complete!"
                Start-Sleep -s 3
           
}

Enjoy!

When you are using Convertto-HTML, you can easily customize your reports by using the -Head, -Precontent, -Body, -Postcontent parameters.

You can insert HTML and CSS into these parameters by using a here-string.

Below is an example on how to use some of these parameters to customize an Event Log Report.

$Head = @"
<style>
body { background-color:#f6f6f6; font-family:calibri; margin:0px;}
TABLE {border-width: 1px;border-style: solid;border-color: black;border-collapse: collapse;}
TH {border-width: 1px;padding: 3px;border-style: solid;border-color: black;background-color: #34495e; color:#ffffff}
TD {border-width: 1px;padding: 3px;border-style: solid;border-color: black;}
TR:Nth-Child(Even) {Background-Color: #dddddd;}
</style>
"@
$precontentheader1 = @"
<div style="padding: 20px 0 5px;position: relative;top:0px;background-color: #34495e;margin-bottom:40px;">
<center>
<img src="https://www.joseespitia.com/wp-content/uploads/2015/11/JE-white.png">
<h2 style="color:#fff; font-size:55px;">

$precontentheader2 = @"

$GetEventLog = Get-EventLog system -Newest 100 | Select-Object -property TimeGenerated, Source, Message, Entrytype |  Where-Object { $_.entrytype -eq "error" -or "warning" }
$Errorcount = $GetEventLog.Index.Count

$GetEventLog | ConvertTo-Html -Head $Head -PreContent "$precontentheader1 $Errorcount System Errors Found$precontentheader2" | Out-File Eventlogs.html
