The last day, CMD suddenly encountered a problem: double-click the problem and a flash will flash, and the face will disappear. What about fooling me? As a result, even the several batches of processing cannot be used. Each time you go back to the data center, you have to manually set IP addresses, WiFi hotspots, and goagent stopped. I found the cause on the Internet and found many methods that are recommended without a Failover header, such as: winkey + R. Do Not Enter cmd. If you cannot enter command, Enter command (in fact, there is no difference ); we also recommend that you find the CMD file and run it as an administrator. We also recommend that you use the guard to fix it. Obviously, this is not acceptable. Self-help clothes and food. At first, I thought it was the reason for the firewall. As a result, the firewall could not be turned on or off. I thought it was possible that there was a problem with the CMD file, and I found myself lying in the System32 folder; is it a group policy issue? Go to the Group Policy and find the "disable command prompt" item. This item is in the disabled status. If there is a good language foundation, I know that this double-layer denial is positive, that is, the Group Policy allows the command prompt to be run; I looked for the Registry, and found too many items. It took several days to identify another cause that might cause no response to cmd running-image hijacking. What is image hijacking? Image File Execution options (actually called "image hijack ".) It provides special environment settings for program execution bodies that may cause errors when running in the default system environment. It is a normal program. No matter where it is stored, or if a program has been repaired by the installation disk again, it cannot run, or the error message is "file not found" or the response is not directly run, or for example, running program a becomes execution B (possibly a virus ), however, it can run normally after being renamed. I am not very familiar with the above statements. I understand that some programs may run incorrectly, so I need to provide special environment settings for these programs, because of this, if you modify these special environment settings, the program may run incorrectly. The most common error is the replacement program, that is, you want to run program A. As a result, it runs program B and replaces program B with a virus. For image hijacking, you can delete the image from the registry.
File Execution options item, but there is a ready-made software autorunschs,: Unknown.
To sum up the reasons why cmd cannot be used:
1. The CMD file is corrupted. Find the same system and copy it to c: \ windows \ system32.
2. The Group Policy is forbidden. Enter winkey + R and gpedit. MSC enters the Group Policy. In turn, choose user configuration> management template> system, and find the "block access command prompt" item. Note that it must be set to "forbidden.
3. Open the firewall. Some code running in batch processing requires support from the firewall. For example, if a Wi-Fi hotspot is set up, it cannot be used without enabling the firewall.
4. Run as administrator. Not all command prompts must be run as administrator. If batch processing fails to run as administrator, it does not work.
5. Use this software to fix image hijacking issues like this.
