explorer sometimes opens slow - RegMon reports ShellNoRoam\BagMRU reads

[Jozsef Bekes]

Hi Guys,

I am a programmer and I never use the built in file browser of Windows
(Total Commander rulez ;-))

But a colleauge of mine (non programmer) does use Windows Explorer, and
sometimes it opens very slow for him. I have done some investigations, and
this is what I have found:

I have attached with windbg and whenever I hit break, explorer.exe was
reading the registry. So I have downloaded regmon and produced a quick and a
slow report. The main difference seems to be that in the slow case
explorer.exe is reading values in the registry under the following path,
around 20 thousands (20000) of times:

HKCU\Software\Microsoft\Windows\ShellNoRoam\BagMRU

I have no idea what this read does and how to fix this. Does anyone have a
suggestion?

Thanks for all answers!!!

Regards,
Jozsi

Looks like an issue with "Remember each folder view" setting. Perhaps
many, many folders?
