To meet this requirement, you must program and modify the image of the System user, that is, the image displayed on the welcome page when logging on to XP, Vista, and win7 systems. Find and ask. There are still no unified solutions and solutions, but there are some gains, as listed below: 1. There is a registry key under XP to save this path: [HKEY_LOCAL_MACHINE/software/Microsoft/Windows/CurrentVersion/hints/Administrator]"Picturesource" = "C: // Documents and Settings // All Users // Applic

/system32" directory of the computer. It allows programs to share the code and other resources necessary to perform special tasks. Many of the applications we use today are not a complete, indivisible, monolithic executable, but consist of a number of dynamically-linked library files that are fragmented and relatively independent. This coincides with object-oriented thinking, which increases the ER reusability of code and facilitates the maintenance and extension of code. ClassificationSome of t

Do you remember. We implement the transfer of privilege level from low to high with call gate and lcall instruction. Let's say we want to move code A to code B, using a call gate G, which refers to a segment of the code B in the target selector in Call Gate G. In fact, we have to consider 4 elements: CPL, RPL, Dpl_b (DPL of Code B), Dpl_g (call Gate G DPL). In the first step, when a accesses call gate G, the rule is equivalent to accessing a data segm

Vista system directory "c:windowssystem32" folder, click "Start → Control Panel" and select "Classic View" on the left, and you will see a new "desktop" entry (with the same name as the Control Panel item in XP). When you want to use the XP-style Desktop Properties Settings window, double-click the "desktop" item. The first run will pop up the window and ask if the Control Panel program is working properly. If normal, click "This control panel works properly" in the prompt box to confirm it. S

The method is to select "Start" * "Search" * "Files or Folders" (in Windows 2000/me), or "Start" * "Search" (in Windows XP). In the first text box in the left panel of the Search Results window, enter "*.cpl", specify the relevant path in the search scope, and click the "Search Now" or "search" button.

lower than the CPL, the RPL covers the CPL. This way even if the segment of the visitor has sufficient privilege level but RPLNot enough to access high-privileged data. Prevent low privilege levels from constructing high privilege level selectors to access high privilegeLevel of data (the current RPL will be placed in the RPL of the selector). If the target code snippet has a low privilege level, it cannot

We can finally look at the code of the 14th chapter by doing so much of the groundwork.For the boot code and user program, still use the 13th chapter, for the kernel program (C14_CORE.ASM), compile a few lines of error, as long as the addition dword can be resolved.1. Why use the call gateIn the 13th chapter, in order to be able to use the kernel-provided routines, the user program is call far transferred directly to the kernel routines (non-Uniform Code snippets) with instructions. Because

In the Registry item HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrent version1_iesexplorer, create a dual-byte value item DisallowCpl and change its value to 1. Create a registry item hkey_current_usersoftwaremicrosoftwindowscurrentversionincluiesexplorer DisallowCpl, and create several string value items under this item in the format of "ser

I believe that cnsmin will not appear in the system. the dll cannot be loaded; If the above method does not allow the system to get rid of cnsmin. if the dll cannot be loaded, click Start or run on the system desktop.

Let's take a look at the figure: This figure shows the system attributes on my C4 2.4/256 sub-host. It is not a picture modification. Modification Method: (this article takes XP + SP2 as an example. Other System methods are similar .) 1. The system file corresponding to the system property is system32sysdm. cpl. We will back up it and then open it with exists. 2. In Resource> Dialog, the form corresponding to 101 is what we want to change. My metho

At present, mainly to

There are two main types: Do not change privileges, change privileges 1. Do not change the privilege level. You can use the inter-segment or intra-segment call or JMP. Do not judge between segments. What is the destination segment?Code. If the code segment is inconsistent, CPL = DPL and RPL If the code segment is consistent and RPL is not judged, CPL> = DPL is required, that is, the outer ring can jum

C99 specification, but so far GCC has not completed full support for the C99 specification.Also attached: C language OriginThe earliest prototype of the "origin" C language was ALGOL 60 in 1963, when Cambridge University developed it into CPL (Combined programing Language). In 1967, Matin Richards of Cambridge University simplified the CPL language and produced bcpl language. In 1970, Ken Thompson of Bell

of a segment error and how the system handles the segment error. The system can process segment errors in three parts: the capture of segment errors by the CPU, the processing of segment errors by the kernel, and the processing of segment errors by user programs.3.1 capture segment errors by CPU The segment error caused by unauthorized access to memory is actually a page exception. The capture of this segment error is included in the capture of page exceptions. The less ancient X86 CPUs provide

This article analyzes the implementation of the Intel CPU quick System Call Command SYSENTER/SYSEXIT introduced in Linux 2.6. Linux drivers and kernel developers can use this mechanism in their own code to improve system performance by understanding the mechanism of fast System Call commands, it also avoids some limitations caused by the fast System Call method (such as nested system calls in system calls ).PrefaceIn the Linux 2.4 kernel, the user-state Ring3 code requests the kernel-state Ring0

Linux Kernel series-5. Transfer of privileges and privileges in operating system development, linux privileges CPL-the privileged level of the currently executed program or task, which is stored in the 0th-bit and 1st-bit cs and ss. DPL-the privileged level of a segment or portal. If it is a data segment, DPL specifies the lowest privileged level for access to this segment. RPL-represented by selecting the 0th-bit and 1st-bit sub-segments. The process
