Windows XP has been criticized for its vulnerabilities due to buffer overflows and its susceptibility to malware such as viruses, trojan horses, and worms.Nicholas Petreley for The Register notes that "Windows XP was the first version of Windows to reflect a serious effort to isolate users from the system, so that users each have their own private files and limited system privileges."
In pre-Windows XP and NT systems (such as DOS and Windows 9x), all users are effectively superusers, and all users have all access rights. In Windows NT and related systems (such as Windows 2000 and XP), a superuser is known as the administrator account. However, this administrator account may or may not exist depending on whether separation up.
Windows 1.0–3.11 and Windows 9x: all applications had privileges equivalent to the operating system;; All versions of Windows NT up to, and including, Windows XP and Windows Server 2003: introduced multiple user-accounts, but in practice most users continued to function as an administrator for their normal operations.
The user-profiling scheme in force today owes its origins to Windows NT, which stored its profiles within the system folder itself, typically under C:\WINNT\Profiles\. Windows 2000 saw the change to a separate "Documents and Settings" folder for profiles, and in this respect is virtually identical to Windows XP and Windows Server 2003.
In Windows XP, every user is set up as an administrator by default (unless added through Computer Management). As a result, most home users ran all their software with Administrator access. As a result, most home users ran all their software with Administrator access.
In addition, an Administrator can use Winzapper to delete specific events from the log. For this reason, once the Administrator account has been compromised, the event history as contained in the Security Log is unreliable. [8] A defense against this is to set up a remote log server with all services shut off, allowing only console access. [9]
One thing was true until Windows 7: the user shouldn't use the Admin account all the time. It needed to have a normal-account for day-to-day use, and an admin account only for making system changes. But with UAC, even and admin need to "authorize" applications to make changes, without this need of logging out and logging in again.
One of UAC's features denies administrative rights to a user who accesses network shares on the local computer over a network, unless the accessing user is registered on a Windows domain or using the built in Administrator account. If not in a Windows domain it is possible to allow administrative share access to all accounts with administrative ...
