No doubt this is one of the most common questions/frustrations about Windows Vista/W7.
Even if you log on as an administrator, you don’t really have administrative rights, thanks to UAC (User Account Control). But since setups require administrator rights this behavior could cause problems.
When you run a setup program, right-click the setup program, and then click Run As Administrator. Then, it will really run as an administrator.
User Account Control (UAC) is a new security component in Windows Vista/W7.
UAC enables users to perform common tasks as non-administrators, called standard users in Windows Vista/W7, and as administrators without having to switch users, log off, or use Run As.
A standard user account is synonymous with a user account in Windows XP.
User accounts that are members of the local Administrators group will run most applications as a standard user.
By separating user and administrator functions while enabling productivity, UAC is an important enhancement for Windows Vista.
To help prevent malicious software from silently installing and causing computer-wide infection, Microsoft developed the UAC feature.
Unlike previous versions of Windows, when an administrator logs on to a computer running Windows Vista, the user’s full administrator access token is split into two access tokens: a full administrator access token and a standard user access token.
During the logon process, authorization and access control components that identify an administrator are removed, resulting in a standard user access token. The standard user access token is then used to start the desktop, the Explorer.exe process.
Because all applications inherit their access control data from the initial launch of the desktop, they all run as a standard user as well.
Strictly speaking it should be impossible for any PDF Reader to display encrypted PDF Documents since they are encryped. But thats not the case – so how is that possible?
Basically when encrypting a PDF Document with a password the encryption key is generated as explained in the PDF specification. This key is then encrypted with the user specified password.
Like that the PDF Reader can decrypt and display the document with the encryption key and without having to know the password.
Now what happens if you loose the PDF Password? Pretty easiy. The Aloaha PDF Editor (included in the Aloaha PDF Suite) allows the user to set or remove the permission password. Aloaha just decrypts the document with the decryption key and then re-crypts the key with with the new permission password.
This shows that the only way to secure PDF Documents is to encrypt them with certificates (for example with the Aloaha PDF Crypter) and NOT just with passwords!
NEW: The new Aloaha PDF Reader is also capable of removing unknown PDF encryption passwords. Just open the document with the Aloaha PDF Viewer and then save as decrypted!
