Let me fix it myself
To resolve this problem, modify the desktop heap size. To do this, follow these steps:
- Click Start, type regedit in the Start Search box, and then click regedit.exe in the Programs list.
If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
- Locate and then click the following registry subkey:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems
- Right-click the Windows entry, and then click Modify.
- In the Value data section of the Edit String dialog box, locate the SharedSection entry, and then increase the second value and the third value for this entry.
- The second value of the SharedSection registry entry is the size of the desktop heap for each desktop that is associated with an interactive window station. The heap is required for each desktop that is created in the interactive window station (WinSta0). The value is in kilobytes (KB).
- The third SharedSection value is the size of the desktop heap for each desktop that is associated with a "non-interactive" window station. The value is in kilobytes (KB).
- We do not recommend that you set a value that is over 20480 KB for the second SharedSection value.
Windows Vista SP1, 7, 8, 8.1 (32bit) / Windows Server 2008 (32bit)
Windows Vista, 7, 8, 8.1 (64bit) / Windows Server 2008, 2008 R2, 2012, 2012 R2 (64bit)
In Windows Vista and in later operating systems, memory allocations are dynamic. Therefore, there is no limitation for memory allocation. However, if you allocate too much memory to the desktop heap, negative performance may occur. This is the reason why we do not recommend that you set a value that is over 20480.
Note The desktop heap size is not affected by the physical RAM on the computer. Therefore, you cannot improve the performance by adding physical RAM.
