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)
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]
Executable space protection on Windows is called "Data Execution Prevention" (DEP). Under Windows XP or Server 2003 NX protection was used on critical Windows services exclusively by default. If the x86 processor supported this feature in hardware, then the NX features were turned on automatically in Windows XP/Server 2003 by default. If the ...
using byte-range locks to arbitrate read and write access to regions within a single file [3] by Windows file systems disallowing executing files from being opened for write or delete access; Windows inherits the semantics of share-access controls from the MS-DOS system, where sharing was introduced in MS-DOS 3.3 . Thus, an application must ...
RUNNING → BLOCKED: A process is put into the BLOCKED state if it requests something for which it must wait. 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).
As a workaround before a patch was available, on December 28, 2005, Microsoft advised Windows users to unregister the dynamic-link library file shimgvw.dll (which can be done by executing the command regsvr32.exe /u shimgvw.dll from the Run menu or the command prompt) which invokes previewing of image files and is exploited by most of these ...
