I opened task manager which uses way too many GDI objects because a Chrome tab was not responding. Kenji Shimizu. This thread is locked. You can follow the question or vote as helpful, but you cannot reply to this thread. I have the same question Report abuse.

In reply to Geethu B's post on March 9, Geethu, How can you possibly suggest that the winforms group is a better place for this question? Windows 7 Behavior: This differs from how Windows 7 behaved. Windows 8 Behavior: In Windows 8, the system will not let you close things down.

Jack Squat. Srimadhwa B. In reply to Jack Squat's post on July 16, Hi Jack, It is been quite some time since the new version of Windows is out and surely there has been many changes made to the operating system which has improved how the new version of Windows behaves and operates.

You can easily verify this limit by running the Sysinternals Testlimit utility with the —u switch, which directs Testlimit to create as many USER objects as it can:. This screenshot shows that, as expected, Windows system processes, including Lsass. One fundamental limitation on the number of USER objects comes from the fact that their identifiers were bit values in the first versions of Windows, which were bit. When bit support was added in later versions, USER identifiers had to remain restricted to bit values so that bit processes could interact with windows and other USER objects created by bit processes.

Each desktop has its own region of memory, called the desktop heap, from which most USER objects created on the desktop are allocated. Because desktop heaps are stored in Session Space and bit address spaces limit the amount of kernel-mode address space, the sizes of desktop heaps are capped at a relatively modest amount. They also vary in size depending on the type of desktop they are for and whether the system is a bit or bit system.

This table summarizes the sizes across Windows versions up through Windows Server R After the release our telemetry showed us that some users occasionally ran out of heap, presumably because they were running more applications on systems that had more memory, so SP1 raised the size to 12 MB.

On versions of Windows prior to Windows Vista, you can use the Microsoft Desktop Heap Monitor tool to view the sizes of the Desktop Heaps and how much of each is in use. However, you can use Testlimit with the —u and —i switches to see how the system behaves when interactive desktop heap exhaustion occurs.

The switch combination has Testlimit create window class data structures that have 4 KB of extra class storage until it fails. Monitoring the Commit Charge limit in the Resource monitor will show which processes consume the most committed memory. If there are processes that are not essential, they may be ended. Large assemblies, simulations, or having many part files open are reasons why the Windows Task Manager count may increase.

The registry can be edited to increase this maximum and thus delay the warning. A registry edit should be completed only if all other options are attempted. The registry entry for both is within these two locations:. When the base is in Decimal, the Object counts can be increased to:.
