Opening "This PC" in any explorer dialog causes freeze

Post by predprey » Thu Aug 09, 2018 2:42 am

Operating System: Windows 10 1803 17134.165
Every time a file explorer tries to open "This PC", the application in question freezes up for at least 30 seconds before the tree node is expanded. Performance is noticeably worse than an unsandboxed explorer.

Hello predprey,

I cannot repro using Win 10 x64 1803 17134.191
Please provide all the required information:
viewtopic.php?f=11&t=19746

Add the following:
Test inside a new Sandbox with default settings
Sbie Control --> Sandbox --> Create new Sandbox
Ensure the bottom part (copy settings) is set to None

Also, please include your configuration file
Configure --> Edit configuration
Copy/paste the contents, highlight them and click on the "</>" button for format them in your response.

Are you using any Explorer addons? (Such as total commander or similar?).
Do other explorer folders load up fine?
How about programs / files, do they work fine in the sandbox?

Regards,
Barb.-

Sorry, here are the information required.
Win 10 x64 1803 17134.191
Sandboxie 5.26 x64
Windows Explorer
Running MalwareBytes 3.5.1.2522 with real time protection
To reproduce I can just "Run Windows Explorer" and the window pops up but takes a while to load up the devices and drives section. I have 2 secondary drives and 1 bluray drive. Problem still occurs even if I wake the secondary drives if they were spinned down from inactivity.

Config file:

Code: Select all

I have OneDrive disabled and the folder removed. 7zip and MBAM context menu are enabled. No other explorer addons I can think of.

Thanks.

Hi predprey, when I run File explorer sandboxed in my W10, for the drives to show up takes a few seconds but it doesn't freeze at all and I can navigate away right away if I want to. I think its been like that for a while. Is this what you are seeing? Picture 1, when I click to run explorer sandboxed. Picture 2, after about 6 seconds. As far as I can tell, there is no issue. If you are experiencing freezes, perhaps its been caused by Malwarebytes.

Yes, this is what happens for me, thanks for the screen caps. I don't recall having this issue back on Windows 8.1 and a few versions back though. It only takes longer to load on Windows Explorer and does not freeze up , but in other programs they may become unresponsive while loading. Any ideas why this only occurs within a sandbox?

The one thing I can think of is perhaps Malwarebytes is interfering with Sandboxie. If you only use one sandbox to run programs then try running programs in another sandbox with default settings and/or disable or uninstall Malwarebytes (for testing). It wouldn't surprise me if MB freezes programs when they attempt to start and run in the sandbox. For testing, its better to uninstall. In my personal case I dont feel any problem with any program that I run sandboxed in W10 or W7. Everything is running nice.

Uninstalling Malwarebytes didn't fix it. I'm thinking its some issue with Windows 10 Creator's Update since I kind of remember this problem appearing since around that time.

Hello predprey,

Let's see if we can find any clues in the Resource Access Monitor log:
https://www.sandboxie.com/ResourceAccessMonitor
Launch Res. Acc. Mon.
Reproduce the issue.
Copy-paste the Res. Acc. Mon output and paste it here.
Highlight the output you just pasted and click on the "</>" button in the forum to format it

Regards,
Barb.-

Re: Opening "This PC" in any explorer dialog causes freeze

Post by Barb@Invincea » Fri Aug 10, 2018 12:29 pm

Hello predprey,

I am not seeing any differences between your output and mine. I still cannot reproduce any kind of delay/freezing when opening "This computer" sandboxed (or Windows explorer).
(...)Windows Explorer and does not freeze up , but in other programs they may become unresponsive while loading...
I could use some clarification as to what is really happening, so that I can further test. Repro steps will be apprciated.

Do you have any addons in explorer, or are you using any themes...anything that is not "the default" ?
Can you provide a screenshot of the issue ?

I take it that this problem does not occur outside Sandboxie, correct?

You can try blocking this class...Not sure what would be the effect (so far, I have not found any issues closing it, but I recommend to try this in a Test Sandbox)
Create a new Sandbox
Right on the Sandbox --> sandbox settings -->Resource Access --> COM Access
Paste this
{9BA05972-F6A8-11CF-A442-00A0C90A8F39}
Apply and Ok your way out.
Configure--Reload configuration
Re-try launchng Explorer in the Sandbox (If no difference, revert the changes).

Regards,
Barb.-

Bo's first screenshot shows the issue. An unsandboxed Windows explorer when opened with "Win Key+E" instantly loads the "Devices and drives" section, but just browsing to "This PC" in any sandboxed application will take a while to load, such as is the case in Bo's screenshot where the address bar indicates it is still loading, which can take up to 30 seconds. I can reproduce the issue by opening "Run Windows Explorer" on any sandbox since I set my Explorer to defaults to "This PC". But even just refreshing the "This PC" directory will take another 30 seconds.

Blocking this {9BA05972-F6A8-11CF-A442-00A0C90A8F39} didn't work.

EDIT: Here's a video to better show the problem.
https://drive.google.com/file/d/1OiVpgT ... sp=sharing
I first launch a Windows Explorer on a completely new sandbox with default settings, and it takes around 25 seconds to load completely.
Nearing the end I launch an Explorer window unsandboxed and it loads instantly.

predprey, I know the loading of sandboxed explorer in my W7 is not as slow as in W10, its inmediate. But either way, in my case, I dont consider the slow loading of sandboxed File explorer in W10 as a problem as I dont experience freezes or delays other than the loading that takes a few seconds. You mentioned noticing this since 1803 came out but I know for sure its been like that from before as I know I had noticed it way back. If I was you, if there's no freeze after File explorer is fully loaded, I wouldn't let this bother me.

Yea, its not a major bug, but it can be a real annoyance where i have to wait every time I want to open a file or directory. It would be nice to know what is really causing it on Windows 10 though, like a side effect for a compatibility patch or something?
