I don't see the key "http" in HKEY_CLASSES_ROOT, but when I try to create it,
it says "File exists"

This is if not dupe but at least similar to bug 34206 (see the screenshot).

This issue seems to have been fixed. Can anyone else confirm this?

I'm using wine-2.8-25-gbe12c5b.

I can't create http in HKCR, because it does actually exist, so error message
is correct. Not sure what original report was about. Could it be 32/64 bit
issue?

It seems that many keys in HKCR, including "http", were not being displayed in
regedit for some reason. These keys did actually exist, which is why the error
message occurred.

But it looks like this bug was fixed somewhere between Wine 2.0-rc5 and Wine
2.8.

Clean prefix I can see http and https under HKEY_CLASSES_ROOT.

wine 2.8-git.

I cannot reproduce this in 2.8, 2.0, 1.8.6, 1.6.2 nor 1.4.1. It looks like a
broken prefix if you see picture at comment 0. It is missing all entries
started with "." and also all Microsoft, Msxsml...

You'll have to be more specific. Is it your own wine build or you're using
packages, if so where did you get the package? Does it happen with both 64 and
32 bit prefixes? If it happens with 64 bit only, are you running 32 bit or 64
bit regedit?

The problem is only with a 64-bit prefix. Both 'C:\windows\regedit.exe' and
'C:\windows\syswow64\regedit.exe' behave equally. I installed wine from
Archlinux repo.

Hmmm. I've just compiled the latest git on Debian Stretch 64-bit, but I still
can't see this bug. I don't have regedit.exe in C:\windows\syswow64 though.

I wonder if this is purely a problem with Arch Linux?

I'm on Archlinux and this problem happens with 64-bit prefix in wine-staging
2.9. HKCR shows A LOT more keys in 32-bit prefix.

Confirming. I've been able to reproduce this behaviour in Arch Linux and Debian
Stretch using the development and staging builds.

32-bit prefixes are not affected.

Running 64-bit regedit in a 64-bit prefix (i.e. using 'wine64') is also fine.

The problem is with WOW64 builds - running 32-bit regedit (i.e. using 'wine')
on 64-bit prefixes.

Unfortunately, the RegOpenUserClassesRoot function is only a stub. This is
almost certainly the cause of the bug.

CC'ing Sebastian. He might like to look into this.
