How to disable DCOM support in Windows

Summary

The Distributed Component Object Model (DCOM) is a protocol that enables software components to communicate directly over a network. Previously named «Network OLE,» DCOM is designed for use across multiple network transports, including Internet protocols such as HTTP. More information about DCOM, visit the following Microsoft Web site: http://technet.microsoft.com/en-us/library/cc958799.aspx
DCOM is supported natively in Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003.

Warning If you disable DCOM, may you may lose operating system functionality. After you disable support for DCOM, the following may result:

Any COM objects that can be started remotely may not function correctly.

The local COM+ snap-in will not be able to connect to remote servers to enumerate their COM+ catalog.

Certificate auto-enrollment may not function correctly.

Windows Management Instrumentation (WMI) queries against remote servers may not function correctly.

There are potentially many built-in components and 3rd party applications that will be affected if you disable DCOM. Microsoft does not recommend that you disable DCOM in your environment until you have tested to discover what applications are affected. Disabling DCOM may not be workable in all environments.

Support for DCOM on all Windows NT-based operating systems can be disabled. To disable this support, follow these steps.

Note To disable DCOM on a Windows 2000-based computer, you must be running Windows 2000 Service Pack 3 (SP3) or later.

Disable Windows 10 services to improve performance: Pros & Cons

• Frees up memory and boosts Windows Performance.
• Can assist you in troubleshooting a problem.

• Will stop certain Windows quality-of-life features from working.

You can safely disable all 48 Windows 10 services listed in this guide. However, it’s important to note that you may still need some of these services, depending on how you use your computer.

For instance, if you are a gamer, it would be inadvisable to stop the Xbox-related services. Thus, you should apply the tips in this guide with a bit of discernment.

Some of the functions of these services can be replaced with third-party applications. For example, you can replace the Windows Search service with a third-party file finding program.

Disabling these Windows 10 services isn’t permanent. Make a note of each service you disable. You may be required to re-enable them in the future.

Its a universal feature available within win and most third party programs, and as such I dont believe it can be disabled.

Perhaps you would care to explain why you wish to do so.

If you are running a desktop keyboard, toggle the ‘lock’ key. This releases the F keys from the original hard wired configuration that go back to the earliest days of computing and allow Windows programs to reuse for other functions.

Even so, many Windows programs still set the F1 key for ‘help’. It is the way things are and ALWAYS have been..

For future users coming in off Google, don’t listen to these non-helpful responses above. This is how you do it: for Windows 10 (you can do any one of the three, you do not have to do all of them):

1) Navigate to C:\Windows, find helppane.exe, right click, Properties, Security tab, Advanced. On the top where it says «Owner:», hit change. Type in your username and hit Check Names, click OK. Apply. Hit okay back to the Security tab. Next to «to change permissions, click edit» hit Edit. Hit Add, type in your username and click Check Names. Hit okay and then on the permissions give yourself Full Control with all boxes checked. Click Apply, yes, then OK. Ok again to close the box. Then right click, rename it, hit enter and click Continue to provide administrator permission. to rename it. Or simply click the file and press Delete on your keyboard to get rid of it. Now you can press F1 without having to be bothered by the help pane popup!

2) Open up command prompt, File, run new task, type in regedit and hit enter. Click yes if there is a popup.

Please backup your registry before making any changes by clicking File > Export (make sure All is selected under Export Range). Make sure to scroll up and select the uppermost level before searching, for me it is «Computer». Then Edit > Find. Under Find What: helppane.exe and make sure only Data is selected and nothing else. This should lead you to the keys that point towards the executable which you can then rename or remove at your own risk.

3) Use a program like Sharpkeys (search it online) to disable the F1 button (not recommended as it will disable the button entirely).
