Export and Import Registry Keys in Windows

What do you mean by "the registry crashes"? What exactly do you see happening? The RegEdit window disappears?

I assume your "yes" means that the RegEdit window closes but there are no other symptoms.

yes the person in question had ESET installed, after uninstalling ESET this happens

Since this happened after an uninstall I suggest
1 Check the ESET website for an uninstall tool. If they provide one then use it.
and then
2 SFC-DISM - TenForumsTutorials [Option 3 and do note the Dism command to run whilst online if SFC reports irreparable errors]
and then, if the fault persists,
3 Repair Install - TenForumsTutorials [despite its name, this is a repair procedure not a re-installation].
and then, if the fault persists, both

4.1 See if the fault happens in Safe mode. If it does not then an installed application is causing the problem.
Boot into Safe Mode - TenForumsTutorials

and

4.2 See if the problem occurs for another user account. Create a new local user account for this test if you do not already have one

Add Local Account or Microsoft Account - TenForumsTutorials
Put a decent password on it so you need not be in a hurry to remove it after the test [and write the password down somewhere secure yet accessible]

Best of luck,
Denis

I'm sorry, the person having these issues has not yet contacted me. I will reply immediately after that.
