In Windows 7, the "enable or disable WINDOWS function" dialog box is blank)

Windows 7
It's really good. I 've been trying it out since the beta version was released, but a serious problem has always plagued me, that is, after the system is used for a period of time, the "open or close windows function" dialog box is blank, so that the system cannot enable or disable some functions. IIS is the most influential. More seriously, Windows
Modules
The installer service cannot be started, and the error 1450 is reported: the requested service cannot be completed due to insufficient system resources. This will cause the system update program installation to fail, the system cannot be updated, and the system is based on Windows
The installer program cannot be installed, and various repair measures do not work, and the SFC/scannow command cannot be completed. For this reason, I had to abandon windwos 7 to switch to XP.

Windows 7 has been officially released recently, so I have not been able to hold back the XP lattice installed on Windows.
7. After a week, there was no blank dialog box in the "open or close windows function" dialog box, so I switched my computer to Windows.
7. After a few weeks of normal use, I secretly suspected that the above bug had been fixed. However, I am not happy for a few days before the Organization's computer has a problem: the "open or close windows function" dialog box is blank; windows
The modules Installer Service cannot be started, and the SFC/scannow command cannot be completed ...... Crash :(

However, when I got home, I found that my computer was normal. Will it be because the system was damaged by software installed on my computer? After comparison, it is found that the unit computer is installed with ArcGIS more than the home computer.
Could it cause top9.3? After careful consideration, the company computer is installed with ArcGIS.
Top9.3 is incorrect. So I searched the dog and found a solution.

The solution is as follows:

In the run, enter Regedit to open the Registry Editor and find HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control. Change the value of registrysizelimit (REG_DWORD type) to ffffffff (10 hexadecimal is
4294967295) restart the computer and run "SFC/scannow" as an administrator. After scanning is complete, everything will be okay. The familiar "open or close windows function" window will pop up. This problem occurs mainly because the registration space is limited after arcgis9.3 is installed. You only need to modify the registration space.

1. Enter Regedit at run to open registry editor
2. Find
   HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control
3. Set registrysizelimit (REG_DWORD type)
   Change the value of to ffffffff (10 is 4294967295)
4. Restart the computer
5. Run "SFC/scannow" as an administrator"
   After scanning, everything will be okay.

How about it? The familiar window "open or close windows functions" is displayed.

This problem occurs mainly because the registration space is limited after arcgis9.3 is installed. You only need to modify the registration space.
