How to solve the four hot problems of Microsoft Windows7 system

The most used operating system is estimated to be win 7, he has won the favor of everyone with excellent display effect, but do you have any opinion on win 7? After Microsoft released the Win7 operating system, users have been acclaimed for this system. However, there are still some minor problems in the application process. Let us look at the solution to the problem.

First, solve the Win7/WinVista folder sharing problem

A friend who installed Win7 and Vista dual system may share the password protected share when sharing files in Win7/Vista . This way you need to add the Everyone or Guest permission when sharing the folder. Generally, when you share a folder, it is a wizard. Adding user settings is easy and there is no problem.

But I’ve run into problems when I see some people sharing the drive. That is, the network neighbor can see the shared drive, but the access does not have permission. Since the shared drive cannot use the wizard, only the advanced share can be used, but the permissions of Everyone have been added to the advanced share. In addition to the corresponding permissions, the share is also subject to the NTFS permissions of the file system.

So you must also add the appropriate NTFS permissions in the drive's security tab, and the drive formatted under Win7/Vista and the following directories by default do not have any permissions for Everyone and Guest. However, since the permissions of NTFS are automatically matched and updated when sharing by wizard, the general shared folder does not encounter problems.

The default folder permissions under Win7/Vista are different from those of xp. The default permissions for drives formatted under Win7/Vista are: AuthenticatedUsers (this is not available for XP), Systemadministrators administrator group, Users restricted user group, and XP default permissions are: administrators administrator group. CreatorOwner creates the owner of the folder, which Vista does not have.

EveryoneXP drives have read-only permissions by default. Although SystemUsers has some different permissions, there are also differences in the default folder permissions created by default.

But the biggest difference is the owner. The folder owner created under XP is the specific user who created the folder, so after setting up the permissions folder, the unknown account displayed by SID will appear after NTFS. The default owner of Win7/Vista is the group. For example, if you are an administrator, the folder owner you create is the administrators group. Therefore, the folder created under Win7/Vista does not have the corresponding permissions of CreatorOwner.

Solution: Just right click on the shared folder you created or on the NTFS format disk/property/security: in the group or username, click on “Edit” Click “Add”, enter “Everyone>;“OK" in the Enter the object name to select ”. The XP machine can access the shared drives and folders you created in Win7/Vista.

Second, the volume of the small speaker does not appear volume adjustment button

Right button is a response, click the left button should appear the sound level adjustment, but now click the left button does not respond at all.

Solution: In this case, as long as the startup item in the registry restores the deleted item. “Start”——“Run” After entering regedit to open the registry, open HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun in its right window and create a new string "Systray" (right click on Run), key value (in Systray) Double click on Edit) as "c:windowssystem32Systray.exe".
