Explorer Freezing Windows 10

[Fidelia Boldul]

Iam having trouble with dropbox working through my Windows file explorer. For some reason, within the last week every time I try to navigate to one of my dropbox files the file explorer crashes and I have to force close the program. I can open files from the specific application. For instance, if I open Word and then open a file from word it will open, but if I try to open the same file from the windows file explorer it freezes. I have tried to uninstall and reinstall. Any other suggestions/solutions?

It is interesting that you believe it isn't a dropbox issue when it only happens with my dropbox folder. All other folders and drives are working appropriately. Yes, I have restarted and checked for other windows updates and storage issues.

This happened yesterday. Everything that had to do with windows explorer started freezing or super slow. Saving files, opening file explorer, everything. (not specifically my mycloud home drive)

Tried every method online, cleaning cashes, disabling explorer features, I was getting desperate. Nothing would work. Rebooting made the explorer work normally for a few minutes, then trying to open it gave me a white loading window.

Out of nowhere I decided to quit dropbox, nothing happened. Then I did the same for the WD Discovery app from the trey icon, and instantly explorer started working again with no issues at all and it opens normally in about 0.01 seconds.

A geek would probably post a screenshot of the task manager CPU or even a process explorer shot of the WD processes (wdsync, WD Discovery, kdd). If you are not running a background sync or copying files to and from the MCH, those processes would be nearly zero and Windows Explorer will not freeze or do any of that.

Another home user mistake is that most home users have slow upload speed so when they have Windows Explorer connected to a MCH remote or relay folder, they think that windows will behave the same as if the file folder was on their desktop with instant access. The home user should know that upload and relay server speed will often limit access to some minutes for explorer to respond with every click within the mycloudhome window and hangs explorer yet my wdmycloud smb devices responds fine on the same network and same switch and router and same end device.

If one is just using the limited My Cloud Home SMB LAN supported drive, clearly one does not need WDD and can map the SMB directly in file explorer address bar with \\Mycloud-XXXXXX where the last 6 chars are those of the serial number on the bottom of the MCH.

WDD allocates a 2 GB cache disk space on the Windows partition and any slow down of the Windows drive, a slow HDD instead of SSD for example, or a lack of disk space on the Windows drive will also appear to freeze file explorer. However this is usually not the cause of any slow down. The primary cause is the slow speed of the remote connection and it is usually a mistake to point a file explorer to a remotely mounted My Cloud Home with many files or many large files as WDD will try to read a lot of that into the cache and will delay the file explorer process (2 GB cache will take 30 seconds to a few minutes to fill with a slow remote upload typical of a home internet).

I have two networked devices, my old wdmycloud and the newer MycloudHome, the former works fine the latter hangs. The MyCloudHome is not publishing shares unlike the wdmycloud which is why I use WDDiscovery for the MyCloudHome device.

Your suggestion about the cache is interesting though , do you know where the cache is stored on the C partition, could it be windows defender putting restrictions on the device so perhaps excluding the cache from defender might be an option. Just a thought. Thanks.

If the generated logs are larger in size, you can upload the logs to google drive or we.tl (7days link validity for free users) or ask the support team to provide you with the online link & password of bitdefender cloud where you can upload the logs and share the upload link with the support team.

The engineers would require some samples/logs from your device to diagnose this. Can you get in touch with them so they can investigate further? They will advise what is required from you to proceed with the troubleshooting process, as I don't think we can get to the bottom of this on the forum..

Unfortunately I have completely wiped the system and did a fresh install since I had the issue, But I do know somethings, First it has something to do with a recent windows updates that broke something with my AMD Drivers and the only way to resolve the issue was to uninstall Bitdefender or uninstall my graphics driver so I choose Bitdefender as it was the least painful of the two.

all of the sudden, yesterday, I started to have issues as well. I am on win 11 pro and first started with losing internet. Chrome gave me an error: dns_probe_finished_bad_secure_config. I received this error even after reboots. I later realized this only affected Chrome as Edge worked fine.

After multiple reboots my computer started freezing. It would continue to freeze on further reboots. My computer worked fine once in safe mode. I rebooted back to normal windows from safe mode without making any changes to my computer. This time I was able to use my computer but once again chrome did not work. I uninstalled BD and chrome started working again. I reinstalled BD today. Now my internet drops on this particular computer for everything, not just chrome. I troubleshooted the issue to be BD firewall. Once I shut the firewall down my internet comes back online. I am on build 27.0.14.69 engine 7.94856

I have the same issue as Snapper and Lockhart. Explorer freezes since the last Windows 11 update and the update of Bitdefender. It is an issue on Windows 11 only as BD works fine on my Windows 10 notebook.

The first troubleshooting step, as suggested by the Support engineers as well is to temporarily disable the security modules in Bitdefender to find out which one is the culprit. Based on @TipTopTom's findings and after consulting with our developers I'm inclined to think that the firewall might actually be causing this somehow, but I'm not sure yet.

@Alexandru_BD : Only a deinstallation solved the problem for me. Just to disable all the modules did not help. I do not have issues with the internet connection, "only" with the freeze of the "File Explorer".

I sounded the alarm, but please note that your request will still have to go through the Support teams for analysis. If this situation is widespread, the insights collected by the engineers will help them investigate and solve this quickly. Otherwise, our powers are limited here in the community, as we can't gather the necessary logs and they are mandatory for the development teams get to the bottom of this in a timely fashion. This way we can also tag the cases and see how many reports are out there.

Another short update: apparently, the issue is fixed with the latest version (27.0.14.78, release date 11 July 2023). However, I was not yet able to update to that version so I cannot confirm that it is solved. (even with the manual update option I am still on version 26). Support team is informed accordingly. Hence I am waiting for the latest release or comment.

Installed Bitdefender, and immediately after the first reboot, my explorer.exe and Windows search service are crashing or hanging. I thought I bricked my Windows OS, so already did a clean install twice, but now I know it's Bitdefender itself.

I've seen isolated cases where the firewall was sometimes blocking svchost.exe and other times allowing it, but if the situation you have encountered persists even with the firewall OFF, I would recommend contacting the Technical Support Teams, as more information might be required to troubleshoot this.
