But, it will not contain the expected components. Plus, you may also receive an error message that resembles the following:

Out of memory or system resources. Close some windows or programs and try again.

This problem also occurs because of the desktop heap limitation. If you guys close some windows, and then you guys try to open other windows, these windows may open. But, this method does not affect the desktop heap limitation as well.

How to Fix Out of Memory Error in Windows

In the introductory part, we also have already seen that whenever your system does not have enough memory left to run any application, process. As well as service the Out Of Memory Error java appears. Obviously, this is not the only reason behind this error, many applications take a lot of memory especially heavy applications such as video editors, graphics editors. Moreover, chances are that your system has also been infected via the virus or malware that is taking over the memory. Pending windows update is also one of the causes of this issue as well.

In order to resolve this problem yourself, modify the desktop heap size. To do this, just follow these steps:

  • Tap on Start, type Regedit in the Start Search box, and then tap on regedit.exe in the Programs list or tap on Windows key + R and in Run dialog box type Regedit, tap on OK.
  • Then locate and then tap on the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems
  • Just right-click the Windows entry, and then tap on Modify.
  • Now in the Value data section of the Edit String dialog box, then locate the SharedSection entry. And then increase the second value and the third value for this entry as well.

SharedSection uses the following format in order to specify the system and desktop heaps:

Out of Memory Error


For 32-bit operating systemsincrease the yyyy value to “12288”;
Increase the zzzz value to “1024”.
For 64-bit operating systemsincrease the yyyy value to “20480”;
Increase the zzzz value to “1024”.


  • Well, the second value of the SharedSection registry entry is basically the size of the desktop heap for each desktop. That is associated along with an interactive window station. The heap is required for each desktop that is also created in the interactive window station (WinSta0). The value is actually in kilobytes (KB).
  • The third SharedSection value is actually the size of the desktop heap for each desktop that is actually associated along with a “non-interactive” window station. The value is basically in kilobytes (KB).
  • We do not really recommend that you set a value that is more than 20480 KB for the second SharedSection value.
  • We also increase the second value of the SharedSection registry entry to 20480 as well as increased the third value of the SharedSection registry entry to 1024 in the automatic fix as well.
