MORE INFORMATION

The Support_388945a0 account is no longer used with Windows Vista and newer versions of Windows.

The Support_388945a0 account enables Help and Support Service interoperability with signed scripts. This account is primarily used to control access to signed scripts that are accessible from within Help and Support Services. Administrators can use this account to delegate the ability for an ordinary user, who does not have administrative access over a computer, to run signed scripts from links embedded within Help and Support Services. These scripts can be programmed to use the Support_388945a0 account credentials instead of the user’s credentials to perform specific administrative operations on the local computer that otherwise would not be supported by the ordinary user’s account. When the delegated user clicks on a link in Help and Support Services, the script executes under the security context of the Support_388945a0 account. This account has limited access to the computer and is disabled by default.

The user accounts and groups that are mentioned in the "Symptoms" section are created by the following components.
