It takes two weeks to install Windows 7. Two network connections, one home network and the other unknown network, will appear each time you start the system. However, my computer only has one Nic, therefore, after each boot, you must first disable the NIC before you can access the internet. How can you disable the unrecognized network that starts the boot .. Next, go to the topic.
The unrecognized network is caused by win7's Startup Process of dnsresponder.exe. This is a strange process of bonjour.exe behind adobe ps3 installation. This is a LAN searching process. This folder contains a Bonjour folder under X: \ program Files. . Restart the computer, find the Bonjour folder, delete the folder, and restart the computer to see if it is a network connection .. I hope to help you ..
How to completely uninstall Windows 7 on both systems
At present, window 7 gradually replaces our current computer system. When window 7 enters the stage, do you think it is not suitable? Is it still between window 7 and window XP? To solve this problem, many of my friends have installed a dual system (window 7 and window xp). In this case, I installed window xp on disk C and window 7 on disk D. When I was tired of window xp, you can log on to the Windows 7 system to try it out. But some friends are not used to it. They do not know how to delete window 7. Here we will introduce you to a method.
To completely uninstall Windows 7, you must first process the boot menu of the dual system, and remove the Boot manager shared by the dual system before formatting the partition of Windows 7. The method is as follows:
First, boot to the XP system, and put the Windows 7 installation disc in the computer drive (if the downloaded ISO image file, you can use the Deamon tools or Virtual Drive Manager to read and load the Windows 7 CD image to the Virtual Drive.
Next, click "Start Menu/Run" to bring up the command line window. In the command line window, enter A: \ boot \ bootsect.exe/nt52 all/force and press enter to run the command. Note that, in this example, A is the drive letter of the installation disc of Windows 7. You need to change A to your drive letter based on the drive letter of the installation disc of Windows 7.
Again, the Windows 7 installation CD is displayed. Then, restart the computer and we can see that the Windows 7 system startup Item and early version Windows option in the dual system boot menu disappear and go directly to the Windows XP system, this indicates that the dual-system boot menu has been deleted.
Finally, you can manually delete Windows 7 files and folders, such as program files, users, and Windows folders in the restarted Windows XP system. If there are no other important files, directly format the partition where Windows 7 is located, which is the most convenient. Uninstall Windows 7 in XP.

Manual optimization solution for Windows 7 System Service cleanup
At present, many computer users with low configurations have officially used Windows 7. How can we make Windows 7 run more smoothly on low-configuration computers? Although some software provides a foolish optimization solution, these optimizations often make the user unable to understand, and do not know whether they are true or effective. This article teaches you to manually optimize Windows 7, and objects are the most easily overlooked system services.
First, we will learn about system services, and then provide targeted Windows 7 System Service cleanup solutions based on different requirements of Windows 7 users to improve the running speed of Windows 7.
What is a service?
A service is a program or process used by the system to execute specific system functions. Its function is to support other applications and generally runs in the background. Compared with programs running by users, the Service does not display program windows or dialog boxes. They can only be observed in the task manager.
How do I modify the Service Startup type?
Enter "services. msc or service, you can find the service item, and click it to open the Service Management List window. Double-click a service to view or modify its properties. In the Properties window, you can change the Startup Type to manual, automatic, and automatic (delayed startup) or disabled ".
What is the difference between "automatic" and "automatic (delayed startup?
"Automatic" Boot means that the service item is loaded at the computer startup to support other programs running on the basis of this service. "Automatic (delayed startup)" is a user-friendly design in Windows 7. This method can be used to start the service item after the system starts for a period of time, it can effectively solve the problem of slow startup or slow response of Low-configuration computers due to too many loaded service items.
What is the difference between "Manual" and "disabled?
When the service is started in the "Manual" status, the process is disabled, but can still be activated under certain circumstances. After it is set to "disabled", unless you manually modify the attributes, otherwise, the service cannot run.
Which services need to be manually started?
"Manual" mode, as the name implies, is that such a service will not be loaded as the system starts, but requires activation of other services or after the user enters the service management interface, start it manually or change its attribute to "automatic.
This mode is usually used when you need to enable features that are not enabled by the system. Take the "Application Identity" service as an example. By default, the service is in the "Manual" status, that is, it is not started. However, when you need to use the AppLocker function, you must manually enable the Service (change to the "Automatic" status). Otherwise, the AppLocker function will not work properly.
What should I pay attention to before modification?
Modifying the system service may cause unexpected problems. Therefore, we recommend that you back up the default service status before modification. To open the Service Management window, click "Operation> export list" and select "Save type" as a TXT text file or CSV file. We recommend that you select the latter to open the file in Excel.
In addition, if the system cannot be normally accessed due to a modification error, press F8 to enter safe mode and modify the Service Startup attribute in safe mode.

Use Windows 7 library to manage temporary files
There are many network application programs. In order to speed up the user's re-access, some previously accessed caches will be saved to the hard disk, for example, IE webpage cache, QQ emoticons, image receiving, and Picasa image thumbnail index files. This type of temporary file is very useful. You may wish to keep it and manage it in a unified manner to improve efficiency.
◎ Use a library to centrally manage temporary files
Different programs and the default storage paths for temporary files are also different, which makes it difficult for us to manage them in a unified manner. To manage temporary files frequently, It is cumbersome to view the file size or batch cleanup. In fact, Windows 7 library can be used for unified management.
First, add a temporary file library for Windows 7. Right-click "Database" on the left side of resource manager, and select "New/Database" from the shortcut menu to create a new library named "Temporary File.
Second, display hidden system files. For files whose "attributes" are "system/hidden" or "hidden", you must click "organization/folder and search option" in the toolbar of Windows 7 Resource Manager ", open the corresponding dialog box and switch to the "View" tab. In the list, deselect the "Hide protected operating system files" check box, select "show hidden files, folders, and drives" and click "OK.
Finally, add the temporary file to the database. Right-click the temporary folder to be added. In the pop-up context menu, select "include in Library/temporary file" and add it to library.
Later, you can easily view and delete databases. You can use the search function of Windows 7 to search for specified files and delete them in batches.
Temporary Files whose attributes are "system/hidden", such as the Temporary IE folder "Temporary Internet Files", cannot be added to the library using the above method, you can add the parent directory Windows to the library for unified management.


Practical Tips: how to prevent mutual access between winXP and Win7 files
How to solve the problem that XP/Win7 files cannot communicate with each other, rather than a "only definite solution ". Most of the time, a seemingly unrelated system default setting is likely to cause normal access between systems, so no one can create a perfect solution out of thin air.
There is always no definite solution to this problem. That is to say, a specific solution can be found only when a specific situation occurs. But in fact, we can also summarize a general solution, and then take specific measures based on the general idea and specific problems.
In the case of file sharing or mutual access between Winodws XP and Windows 7 (including mutual access within the LAN and dual-host interconnection), we can start from the following aspects.
1. Whether the firewall is disabled
If you cannot see the other side between Windows 7 and Windows XP, first ensure that the firewall is disabled.
Disable Windows 7 Firewall
After you disable the system firewall for Windows 7 and Windows XP, check whether a third-party firewall is installed. If it is already installed, disable it.
Windows 7 shared folders cannot be accessed on Windows 7 computers. Some of them can see the shared directories under Windows 7, but once they enter the directory, they will prompt that they do not have access permissions.
2. Open a Guest account
Till now, there is no reasonable explanation to explain why not enabling the Guest account affects mutual access between Windows systems. This situation has been proven more than once between Windows 98 and Windows XP. Therefore, you must enable the Guest account for mutual access between Windows XP and Windows 7.
Enable Windows 7 Guest Account
Similarly, you also need to enable the Guest account on Windows XP.
3. file and printer sharing
When a user disables the firewall and the Guest account is enabled, but the mutual access still fails, the user needs to enable "file and printer sharing" under Windows XP and Windows 7 firewalls respectively ".
Enable file and printer sharing under Windows XP Firewall
In particular, if you are using remote sharing for access, you should also find remote service-related items and enable them separately.
4. User Permissions
In Windows 7, Microsoft granted higher security permissions to the administrator account for system security considerations. However, this "high-permission" setting can cause more access barriers during system mutual access. Generally, because Windows 7 systems have a high degree of accessibility to the system, if the system prompts that the permission is insufficient, You need to grant the visitor higher permissions.
TIPS: Security Account permissions in Windows 7
Many users, including Windows 7 users, think that the Administrator account is the owner of the highest privilege in the system. Microsoft also sets a hidden account in Windows 7, which has higher permissions.
Back to the previous topic, because the other party is accessing the network, you may not be able to escalate permissions for the specific access account in the LAN. Therefore, you need to reduce the number of files (CLIPS) to be accessed) that is, the visitor is indirectly granted "full control of permissions ".
Permission to access folders is reduced in Windows 7
Note:
If the user still cannot access Shared Files after setting the above method, we recommend that you switch to the "Security" label in the "123 properties" folder, then, add the full control permissions of the access user to the folder.
5. Security software or system auxiliary software
In the Windows XP era, the well-known System Assistant Software is no longer the master of Windows optimization. On Windows 7, some users still use such software. This type of software is also for the sake of system security. Generally, remote access to the system or folder sharing are disabled. If you have installed such software, you need to check their program settings and whether shared and remote services are disabled.
In addition, in some anti-virus software, they also restrict remote services and access. You also need to remove the restrictions.
