Removing Old and Unused Drivers from Driver Store using Powershell

Each time you install or update your device driver, Windows OS (since Vista) continues to store the old version of the driver in the system Driver Store. Thereby, if the system doesn’t work correctly with the new driver, user can roll back to an older version of the driver at any moment.

Windows Driver Store is located in the folder C:\windows\system32\DriverStore\FileRepository. However, some Windows users began to notice that over time, the folder %windir%\system32\DriverStore\FileRepository begins to occupy more and more disk space. In our example, the size of this folder is more than 11 GB. Quite a lot, especially for the SSD drive!

How to Remove Old and Unused Drivers from Driver Store?

To clear the contents of folder FileRepository from the outdated drivers, we prepared a small PowerShell script, that removes all duplicates drivers except the drivers with the latest date.


Warning! In any case don’t delete any files or folders manually from the directory FileRepository!

Important Tips:

  • To run this script you need to update your PowerShell version to Windows Management Framework 1 (or at least WMF4).
  • Before running the script, make sure you have the current drivers for the video card, printer and other devices, that are constantly in use. In case of problems, you can always re-install properly driver.
  • Also it is recommended to create a restore point. To do this, run the command:
    Checkpoint-Computer -Description “PointBeforeDeleteUnusedDrivers”

    Verify that the restore point was created successfully using the command:


We will get the list of third-party drivers installed in the system by using the DISM command:

dism /online /get-drivers

Then parse the output using PowerShell, select the driver duplicates and sort them by date. From the resulting list we will exclude the most recent version for each driver.

After that, remove remaining drivers using pnputil utility. In some cases, if some driver is not removed, add the -f switch.

The script is as follows:

$dismOut = dism /online /get-drivers

$Lines = $dismOut | select -Skip 10

$Operation = "theName"

$Drivers = @()

foreach ( $Line in $Lines ) {

    $tmp = $Line

    $txt = $($tmp.Split( ':' ))[1]

    switch ($Operation) {

        'theName' { $Name = $txt

                     $Operation = 'theFileName'



        'theFileName' { $FileName = $txt.Trim()

                         $Operation = 'theEntr'



        'theEntr' { $Entr = $txt.Trim()

                     $Operation = 'theClassName'



        'theClassName' { $ClassName = $txt.Trim()

                          $Operation = 'theVendor'



        'theVendor' { $Vendor = $txt.Trim()

                       $Operation = 'theDate'



        'theDate' { # change the date format for easy sorting

                     $tmp = $txt.split( '.' )

                     $txt = "$($tmp[2]).$($tmp[1]).$($tmp[0].Trim())"

                     $Date = $txt

                     $Operation = 'theVersion'



        'theVersion' { $Version = $txt.Trim()

                        $Operation = 'theNull'

                        $params = [ordered]@{ 'FileName' = $FileName

                                              'Vendor' = $Vendor

                                              'Date' = $Date

                                              'Name' = $Name

                                              'ClassName' = $ClassName

                                              'Version' = $Version

                                              'Entr' = $Entr



                        $obj = New-Object -TypeName PSObject -Property $params

                        $Drivers += $obj



         'theNull' { $Operation = 'theName'





Write-Host "All installed third-party  drivers"

$Drivers | sort Filename | ft

Write-Host "Different versions"

$last = ''

$NotUnique = @()

foreach ( $Dr in $($Drivers | sort Filename) ) {


    if ($Dr.FileName -eq $last  ) {  $NotUnique += $Dr  }

    $last = $Dr.FileName


$NotUnique | sort FileName | ft

Write-Host "Outdated drivers"

$list = $NotUnique | select -ExpandProperty FileName -Unique

$ToDel = @()

foreach ( $Dr in $list ) {

    Write-Host "duplicate found" -ForegroundColor Yellow

    $sel = $Drivers | where { $_.FileName -eq $Dr } | sort date -Descending | select -Skip 1

    $sel | ft

    $ToDel += $sel


Write-Host "Drivers to remove" -ForegroundColor Red

$ToDel | ft

# removing old drivers

foreach ( $item in $ToDel ) {

    $Name = $($item.Name).Trim()

    Write-Host "deleting $Name" -ForegroundColor Yellow

    Write-Host "pnputil.exe -d $Name" -ForegroundColor Yellow

    Invoke-Expression -Command "pnputil.exe -d $Name"


Tip. In case you need to show the list of unused drivers only, comment Invoke-Expression (add a # character before the command Invoke-Expression -Command “pnputil.exe -d $Name)

Copy the code of the script and save it to file drv_cleanup.ps1 (to the folder c:\ps). Open the elevated PowerShell console and allow to execute the unsigned scripts:

Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass

Next run the script: C:\PS\drv_cleanup.ps1

powershell remove driver

The script will remove unused drivers. After its completion, restart your computer and check if everything works properly and, if necessary, reinstall the appropriate driver.


In our case, after the execution of the script the size of a folder FileRepository reduced from 11 to 1.5 GB. Not bad!

  1. Hi,

    Great script. Any chance it can be modified to pull driver info out of a standard driver folder and not the windows online driver store?

    As an example, i have a driver folder used for MDT that i need to clean out. Its not part of a windows image so i cant mount it with DISM.


  2. There is a bug: months and dates have to be formated to add leading zeros.
    So, had to replace the date function like this:
    ‘theDate’ { # changed the way the strings are formated so month 03 comes before 12 (was 12 before 3)
    $tmp = $txt.split( ‘/’ )
    $txt = “$(‘{0:d4}’ -f [int]$tmp[2]).$(‘{0:d2}’ -f [int]$tmp[0]).$(‘{0:d2}’ -f [int]$tmp[1].Trim())”
    $Date = $txt
    $Operation = ‘theVersion’
