Why does Win7 open or close the Windows function blank?
Search for this problem on the Internet is quite a lot, under Windows7 "Open or close Windows function" Suddenly, there is a blank, and you can't see it.
Some friends found this problem after making changes to the .net framework option. Some friends have problems after installing ArcGIS 9.3. Of course, there are more friends who don’t know what caused it. .
Either way, you have to solve it. The soft media Xiaobian has compiled several programs to ensure that the friends who have encountered such problems completely solve this symptom. The solution on the Internet is to replace several system files, which is more complicated to operate. Instead, the second solution below allows the system to replace itself with the system files.
Solution 1:
Windows Modules Installer service was inadvertently shut down, perhaps some optimization settings software did not take into account the necessity of this service, you can start this service in the service management. If you have Win7 Optimizer on hand, you can use it with the Service Manager. The system's own service management, you can enter the services.msc in the start menu and press Enter to open.
Solution 2:
If the above service is open, or not. Open the Win7 optimization master, click on the “One-click repair system” in the shortcut, and restart Win7 if prompted. As shown below ——
The principle of one-click repair system is to call the command of the Windows system itself, that is, to execute the sfc /scannow repair command with administrator privileges, the main principle is to detect the integrity of the system file, the system of Windows7 Check the file again and replace it with the most stable DLL and other files that come with the system.
Software Xiaobian Special Tip: This one-key repair system command, please use it well, many systems have problems, you can use this to fix.
Solution 3:
If you still find that it is not fixed, it is possible that the relevant registry key has been modified, run regedit.exe to open the registry editor, navigate to
HKEY_LOCAL_MACHINE\\System\\CurrentControlSet \\Control Here,
Then, change the value of RegistrySizeLimit (of type REG_DWORD) to FFFFFFFF (10294967295 in decimal).
Then log out and re-login or restart Win7.
