This kind of tool is available in 360 computer butler Jinshan Guardian and other software.
Is it a problem for computers to change slmgr -rearm?There are different kinds of secret keys, the first is the installation secret key and the activation secret key. Another way to categorize them is by version. The same system is generally divided into general version, enterprise version, professional version, these versions of the corresponding secret key are not the same, cross use is useless.

Mobile phone wifi identity problems how to fix1, it is estimated that some friends may encounter the connection to enter the key, then the key is the one that you initially open the routing wireless password, as long as you enter the right, you can connect.
2, perhaps there are shoes friends will also encounter like into the connection successfully, has been in the acquisition of IP 。。。。。 Then a long time no response, and then failed to connect. Then like this case, I will give you the reasons.
The reason is, you that the route of the IP also gives you set up to protect, then it does not matter, I teach you as usual to connect successfully into, this time you have to look at your route of the IP is how much, and then enter the cell phone settings, and then into the wireless and the network, and then the WIFI settings, point to open the WIFI, and then search for the wireless that you want to point to the lower-left corner of the fixed touch key, and then enter the manual Edit the IP, as long as the IP is entered correctly, then it is OK!
How to change the IP address (computer explorer.exe has problems)
iexplore application error
1. Send error report
Phenomenon: During the process of browsing the web using IE, the message "Microsoft Inter Explorer is experiencing problems" appears. You need to close ......" message. At this point, if you click the "Send Error Report" button, the error report will be created, click the "Close" button will cause the current IE window to close; if you click the "Do not send" button, it will close all IE windows; if you click the "Do not send" button, it will close all IE windows; if you click the "Close" button, it will cause the current IE window to close. button, all IE windows will be closed.
Troubleshooting This is a small program designed by IE to understand what users are doing wrong, but I don't want to be a "free tester" for Microsoft, not to mention that every day it faces thousands of reports, so who knows if it cares about my report?
Troubleshooting
For different situations, you can use the following methods to turn off IE to send error reports:
① For IE 5.x users, perform the "Control Panel ?ú Add or Remove Programs", and in the list, select "Inter Explorer Error Reporting" option in the list, and then click the "Change/Remove" button to remove it from the system.
② For IE 6.0 users on Windows 9x/Me/NT/2000, open the Registry Editor, locate [HKEY_LOCAL_MACHINE＼Sofare ＼Microsoft＼Inter Explorer＼Main], and in the right-hand corner, select [HKEY_LOCAL_MACHINE＼Sofare ＼Microsoft＼Inter Explorer＼Main]. Main], create a DWORD double-byte value named IEWatsonEnabled in the right pane, and assign it to 0.
③For Windows XP IE 6.0 users, go to "Control Panel→System", switch to the "Advanced" tab, and click on the "Advanced" button. "tab, click the "Error Reporting" button, select the "Disable Error Reporting" option, and select "But notify me of serious errors", and finally click "OK". Click the "OK" button at the end.
2. IE internal error, the window is closed
Phenomenon in the use of IE to browse some of the web pages, there is an error dialog box: "The program performs an illegal operation, is about to close the ......", click on the "OK" button. Click the "OK" button and then pop up a dialog box, prompting "an internal error occurred ......". After clicking the "OK" button, all open IE windows are closed.
Failure to comment on the error generated by a variety of reasons, too much memory resources, IE security level settings and browsing the site does not match, and other software conflicts, browsing the site itself contains the error code ...... these cases are possible, you need to be patient to solve.
Troubleshooting
①Close too many IE windows. If you are running a program that requires a lot of memory, it is recommended that you do not open more than 5 IE windows.
② Decrease the security level of IE. Execute the "Tools ?ú Inter Options" menu, select the "Security" tab, click the "Default Level" button, drag the slider to lower the default security level.
③ Upgrade IE to the latest version, IE 6.0 SP1
You can use an IE-centric browser, such as MyIE2, which takes up relatively fewer system resources and, when the browser is closed due to a failure, the next time you start it, you will be prompted to "open the page where the error occurred last time.
This is the first time I've seen a browser with the same functionality as the previous version.
Possible causes:
First, the problem of network settings
This reason is more often found in the need to manually specify the IP, gateway, DNS server networking mode, and the use of proxy servers to access the Internet. Check your computer's network settings carefully.
Second, the problem of DNS servers
When IE can not browse the Web, you can first try to use the IP address to access, if you can access, then it should be a DNS problem, resulting in DNS problems may be connected to the network to obtain DNS error or DNS server itself, then you can manually specify the DNS service (address can be provided by your local ISP) DNS server address provided by your local ISP, or you can use other places where DNS server address can be used normally.) Do this in the properties of the network, (Control Panel - Network and Unplugged Connections - Local Connections - Right-click Properties - TCP/IP Protocol - Properties - Use the following DNS server address). Different ISPs have different DNS addresses. Sometimes it's a problem with your router or network card that prevents you from connecting to your ISP's DNS service, in which case you can either turn your router off for a while and then back on again, or reset your router.
There is also a possibility that there is a problem with the local DNS cache. In order to increase the speed of website access, the system will automatically store the websites that have already been accessed and obtained IP addresses in the local DNS cache, and once the website is accessed again, it will no longer be accessed through the DNS servers, but directly from the local DNS cache to retrieve the IP address of the website. Therefore, if there is a problem with the local DNS cache, the website will be inaccessible. You can rebuild the local DNS cache by running ipconfig /flushdns in Run.
Third, the IE browser itself
When the IE browser itself fails, it will naturally affect the browsing; or IE has been maliciously modified and damaged will also lead to the inability to browse the web. At this time you can try to use the "Huangshan IE repair experts" to repair (recommended to the safe mode repair), or re-IE (such as reinstallation of IE encountered can not be re-problems, you can refer to: attached to a solution to the inability to re-install the IE)
Fourth, the problem of the network firewall
If the network firewall is not set properly, such as too high a security level, the firewall is not set.
If the network firewall is not set up properly, such as too high a security level, accidentally put IE into the blocked access list, the wrong firewall policy, etc., you can try to check the policy, reduce the firewall security level or directly turn off to try to return to normal.
V. Problems with network protocols and network card drivers
IE can't be browsed, it may be caused by the network protocols (especially the TCP/IP protocol) or the network card driver is damaged, you can try to re-network the driver and network protocols.
Six, HOSTS file problems
HOSTS file has been modified, can also lead to abnormal browsing, the solution is, of course, to clear the contents of the HOSTS file.
Seventh, the system file problems
When the system files related to IE is replaced or damaged, it will affect the normal use of IE, this time you can use the SFC command to repair, WIN98 system can be in the "Run" in the implementation of the SFC, and then perform a scan; WIN2000 / XP / 2003 is in the "Run" in the "Run" in the implementation of the SFC, and then perform a scan; WIN2000 / XP /2003 in the "Run" in the implementation of sfc /scannow try to repair.
Which when only IE can not browse the web, and QQ can be on, it is often due to winsock.dll, wsock32.dll or wsock.vxd (VXD only exists under the WIN9X system) and other files are damaged or missing caused by the Winsock is an important part of the composition of the TCP / IP protocols, the general reinstallation of the TCP / IP protocols. IP protocol. However, XP started to integrate the TCP/IP protocol, so it can not be simply uninstalled and reinstalled like 98, you can use the sh command to reset the TCP/IP protocol, so that it is restored to the state of the initial installation of the operating system. The specific operation is as follows:
Click "Start Run", in the Run dialog box, type "CMD" command, pop-up command prompt window, and then type "sh int ip reset c:\ resetlog.txt". resetlog.txt" command will return to the car, which "resetlog.txt" file is used to record the results of the command execution log file, the parameter option must be specified, the complete path of the log file specified here is The full path of the log file specified here is "c:\resetlog.txt". The result of executing this command is the same as removing and reinstalling the TCP/IP protocol.
Tip: The sh command is a command-line based scripting tool that you can use to configure and monitor your Windows system, and it also provides an interactive network shell program interface, the format of the sh command can be found in the help file (in the command prompt window, type "sh/?"). in the prompt window).
The second solution is to repair the above files, WIN9X use SFC to re-extract the above files, WIN2000/XP/2003 use sfc /scannow command to repair the file, when sfc /scannow can not be repaired, you can try to publish a repair tool WinSockFix specifically for this problem, you can search for downloads on the Internet. You can search online and download it.
Eight, the real-time monitoring of antivirus software
This is not often seen, but sometimes it does have to do with real-time monitoring, because the real-time monitoring of the antivirus software are now added to the monitoring of web content. To cite an example: KV2005 will be in the individual machine will lead to IE can not browse the web (many friends have encountered), its specific performance is as long as the opening of the web page monitor, a boot online about 20 minutes, IE will not be able to browse the web page, this time, if the web page monitor KV2005 off, everything is back to normal; after a thorough reinstallation of KV2005 can not be resolved. Although not every machine with KV2005 installed will have this problem, after all, the system of each machine is different, and the installed programs are not the same. However, if there is IE can not browse the page, also pay attention to check the antivirus software.
Nine, Application Management service problems
Only on the QQ can not open the situation of the Web, restarted after the good. The first thing you need to do is to get the right kind of information from your computer, and then you can use it to help you get the right kind of information from your computer. The reason for this is not clear.
Ten, infected with a virus caused
This situation is often manifested in the opening of IE, in the IE interface in the lower left box prompts: is opening the web page, but the old half a day did not respond. In the task manager to see the process, (into the method, put the mouse on the taskbar, press the right button - task manager - process) to see how the CPU occupancy rate, if it is 100%, you can be sure, is infected with viruses, this time you want to run the other programs are simply suffering. This is to find out which process is greedily occupying the CPU resources. Find, it is best to record the name, and then click on the end, if you can not end, it is necessary to start to the safe mode to delete the thing, but also into the registry, (method: start - run, enter regedit) in the registry dialog box, point edit - find, enter the program name, find, point the mouse! The right mouse button to delete, and then a few more searches, often can be completely removed cleanly.
There are a lot of viruses out there, and the only way to get rid of them is to do it manually.
