7 Secret Settings to Inspect Poor PC Speed After Malware Removal

In this article, I will share another method to address the issue. This time I used the following registry modification to fix the issue. The problem was related to the SMB2 cache redirection as explained by Microsoft in the article SMB2 Client Redirector Caches Explained. In Windows 10 version 1709 (Fall Creator’s Update), there is a registry key that disables guest access on SMB2 called "AllowInsecureGuestAuth". Below are the settings changed by the group policy.

Network Access
Manager Deployment

You can save it into a ‘.reg’ file and double-click the file to use, or you can just set them manually with RegEdit. The following method is useful to Windows 10 Home users who don’t have access to the Group Policy Editor.

Disable Network Access To Registry In Windows

This in no way impacts regular GUI-based (userland) UAC. You are always free to disable or delete a rule – if you change your mind on the blocking of internet access for a specific application. The vast majority of third-party applications on your computer can access the internet – and they tend to do so for different reasons. However, there are times when you do not want a specific app to use the internet.

  • option in the Network Groups window, end users can add user networks to the active group or delete user networks from the active group.

Last year I wrote this article What to Do When Creating Folders or Accessing Files on Remote Computer is Very Slow. In that article I mentioned several troubleshooting techniques and tips on fixing the issue of slow network access to shares.

If you are on Computer A and the access to shared network files on Computer B is very slow, then you will make the change in the registry on Computer A where you are experiencing the problem. It’s possible that you may experience a significant performance hit by disabling these caches. If that’s the case, simply re-enable these caches by deleting these registry keys. Deleting them will set it back to their default values, zlib1.dll or you can manually change the values to their default settings. The default values are supposed to work for most scenarios, but that’s not always the case.

I will never use the search for a couple of reasons. First, I don’t need it there as I want local files and settings to be returned exclusively when I run a search on Windows 10. If the target computer is not a member of a Windows 2003 or later Active Directory domain, the most likely cause is that the target computer has Remote UAC enabled. Remote UAC prevents local administrative accounts from accessing ADMIN$ by preventing local admin accounts from running in an elevated mode from a network connection. To access ADMIN$ using a local account, Remote UAC will need to be disabled.
