In een 64bit installatie kan powershell in 32bit of in 64bit mode opgestart. Afhankelijk van deze mode zal de default registry key waar powershell naar toeschrijft of van leest verschillen. Om een script geschikt te maken voor beide runmodes kun je in het script bepalen welke versie is opgestart, de 32bit of de 64bit versie. Afhankelijk hiervan kun je dan b.v. de default key instellen.
