In the case of executable files, the icon will have a security shield overlay. The following tasks require administrator privileges: [9] [10] Running an Application as an Administrator; Changes to system-wide settings; Changes to files in folders that standard users don't have permissions for (such as %SystemRoot% or %ProgramFiles% in most cases)
Some file systems, such as Btrfs, HAMMER, ReFS, and ZFS, use internal data and metadata checksumming to detect silent data corruption. In addition, if a corruption is detected and the file system uses integrated RAID mechanisms that provide data redundancy, such file systems can also reconstruct corrupted data in a transparent way.

All versions from Windows 3.0 to Windows Server 2003 R2 contain this security flaw. [2] However, Windows NT 4.0 and Windows XP, unless patched, are more vulnerable than earlier versions because their default installation enables Windows Metafile code execution, the source of the vulnerability. [3] Later versions of Windows do not have this ...
A1: A block prevents a user account, an IP address, or a range of IP addresses from editing Wikipedia, either partially or entirely. Blocked users can still open, access, and read any article or page on Wikipedia; they just cannot modify or edit any pages that are restricted by the block.
When the other task is blocked, it is unable to execute until the first task has finished using the shared resource. Programming languages and scheduling algorithms are designed to minimize the over-all effect of blocking. A process that blocks may prevent local work-tasks from progressing. In this case "blocking" often is seen as not wanted. [2]
A request to the OS is usually in the form of a system call, (i.e. a call from the running process to a function that is part of the OS code). For example, a process might become BLOCKED if it is requesting a file from disk or a saving a section of code or data from memory to a file on disk.
When a file with setuid is executed, the resulting process will assume the effective user ID given to the owner class. This enables users to be treated temporarily as root (or another user). The set group ID, setgid, or SGID permission. When a file with setgid is executed, the resulting process will assume the group ID given to the group class ...
A blocked administrator can block the blocking administrator, but should only do so in exceptional circumstances where there is a clear and immediate need, such as in the case of a compromised account. Use of the block tool to further a dispute or retaliate against the original blocking administrator is not allowed.
