explorer sometimes opens slow - RegMon reports ShellNoRoam\BagMRU reads

[Guest 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?
