At my current client, I run a sandbox SharePoint 2010 single server environment on top of Windows 7 with my corporate credential as my service account.

I get a wonderful message saying that my account password is about to expire, so obviously, my heart goes thumping. Here we go again.  It’s time to lose more hours on running around and switching around password within SharePoint 2010 that powers all the web apps, service apps, etc…

However, as per my colleague suggestion, it turned out to be pretty easy:

1. Change your corporate account password using Ctrl+Alt+Delete -> Change Password
2. Run the following command in PS to quickly update everything else.

$cred=get-credential;Set-SPManagedAccount -Identity $cred.Username -ExistingPassword $cred.Password -UseExistingPassword

Restart the IIS via “iisreset /noforce” and you’re all set.
