HP PCs - User Account Control Window (Windows 7)

This document pertains to HP and Compaq computers with Windows 7.
User Account Control informs you when a software program is trying to make changes to your computer that require administrator-level permission. User Account Control helps protect your computer from being changed by an unauthorized source.
User Account Control displays differently for Standard user accounts and Administrator accounts. For more information about the different user account types, see Managing User Accounts and Logins in Windows 7.

Understanding the User Account Control message when installing software

One of the following types of User Control Account messages may appear when installing software.
A setting or feature that is part of Windows needs your permission to start.
This item has a valid digital signature that verifies that Microsoft is the publisher of this item. If you get this type of dialog box, it is usually safe to continue. If you are unsure, check the name of the program or function to decide if it is something you want to run.
A program that is not part of Windows needs your permission to start.
This program has a valid digital signature, which helps to ensure that the program is what it claims to be and verifies the identity of the publisher of the program. If you get this type of dialog box, make sure the program is the one that you want to run and that you trust the publisher.
A program with an unknown publisher needs your permission to start.
This program does not have a valid digital signature from its publisher. This does not necessarily indicate danger, as many older, legitimate programs lack signatures. Some malware and viruses may display this message during installation. You should use extra caution and only allow a program to run if you obtained it from a trusted source, such as the original CD or a publisher's website.
  • If you obtained this software from HP, go to the HP software and driver page for your model to download the latest version.
  • Before installing, update your antivirus definitions and run a scan to detect any malicious files contained in the program.
  • If you are still unsure, do not install the program.
You have been blocked by your system administrator from running this program.
This program has been blocked because it is known to be untrusted. To run this program, you need to contact your system administrator.

HP software or driver shows Publisher Unknown in UAC window

Most software available from the HP web site or installation discs has been signed with a valid digital signature. Some software may prompt the User Account Control window to display the publisher as Unknown.
If the User Account Control message indicates that software obtained from HP has an unknown publisher, go to the HP software and driver page for your model to download the latest version.
