Solve the four hot issues of Microsoft Windows7 system

After Microsoft released the Win7 operating system, users have been acclaimed for this system, however, there will still be some in the application process. Let's take a 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 have encountered problems when I saw 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 security tab of the drive, 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 drive has 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 the NTFS format disk /Properties /Security: in the "Group or User Name" column, "Edit", then click “ Add ”, in the "Enter the object name to select", enter "<;Everyone" point" OK”. The XP machine can access the shared drives and folders you created in Win7/Vista.
Second, win7 volume 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 a little reaction.
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_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run in its right window and create a new string "Systray" (on Run Right click on New) and the key value (double-click on Systray) is "c:\\windows\\system32\\Systray.exe".
Third, can not use Win7ReadyBoost
Computer memory is small, after the installation of Windows system optimized, but then plugged into the USB2.0 flash memory, but found that the ReadyBoost function can no longer be used.
Solution: If ReadyBoost cannot be enabled, it is likely that the optimization software has shut down the Windows 7 Superfetch service. Just restart the Superfetch service to solve the failure that ReadyBoost cannot be enabled. In the search box of the start menu, type "Services.msc" and press Enter to open the service, find the Superfetch service, and change its startup type to "Automatic", and the service status is changed to "Start".
If you are prompted to start the service and say that it cannot be enabled, you can enter “regedit” in the search box of the Start menu and press Enter to open the Registry Editor and navigate to “HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/SessionManager /MemoryManagement/PrefetchParameters”, change the value of the "EnableSuperfetch" on the right side to 3, and then restart the service.
Fourth, solve the problem of idle eSATA interface affects Win7 startup speed
Many motherboards have at least one eSATA interface, which is convenient for users to connect external hard drives and other devices, but many users do not need it, so they are idle. , but this idle eSATA interface may slow down your Windows 7 operating system startup speed?
This problem occurs because the initialization timing and SATA specification of Microsoft AHCI (Advanced Host Controller Interface) is not complete. The match should be such that it takes longer to detect the eSTA interface.
Solution: Microsoft has released a hot fix for this purpose, but it is not publicly available. If you need it, you can request it from the Microsoft Support Center.
