After updating Windows 10 , Batchpatch reported to me the PC access was denied.

After updating Windows 10-20H2 , Batchpatch reported to me the PC access was denied.
Before the update, it was on PC version 1809 and I could control the PC via BatchPatch (I had the firewall turned off, the RPC service is running), but as I ran the update on 20H2, I lost control of this PC, while the firewall is completely turned off (local , private and domain) RPC service is running. I still have Administrator rights, but whenever I want to send anything via BatchPatch, or send any query, it will write “Access would be denied”

“Access denied” indicates that there is a permissions or authentication problem of some kind. We have not ever seen nor heard of any issues that are specifically tied to upgrading to 20H2, so I would suggest you simply re-go-over the permissions/requirements, and make sure everything is in place for that particular computer.

Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
It doesn’t show me this error. Everything is set as it should. Everything worked before the client was updated.

PC-B3-11 has 1809 version and is OK, it can be seen in the picture, now I will upgrade to version 20H2

Now the upgrade 20H2 is installed and it is not possible to connect to the client, while the firewall is turned off, I checked everything, according to the attached links. So I don’t know where to look anymore.

I understand what you’re saying. It’s not clear to me why you would see a change after upgrading, as we have not observed that before, and Windows shouldn’t be making modifications that would lock you out. However, with Windows anything is possible. Even including a bug in the particular build of 20H2 that you have installed. Regardless, BatchPatch didn’t change during the upgrade, the target computer changed. And ‘Access Denied’ is always a permissions/authentication issue of some kind. Specifically, the error you are encountering is occurring when BatchPatch attempts to make a WMI connection to the target computer. I would suggest that you try the following things:

1. Log on to the target computer directly/manually with the same logon account that you are using to attempting to connect from BatchPatch. Just make sure that you’re able to log on successfully with the same username/password.

2. Since you are using a local account (not a domain account), check the registry values described in the section titled ‘Using Alternate Credentials with a Local Account’ at https://batchpatch.com/batchpatch-authentication-in-domain-and-workgroup-non-domain-environments Make sure the necessary registry values were not removed/modified during the upgrade process

3. Test out option 1 and option 2 instead of just option 3 at the following link to see if you experience different results: https://batchpatch.com/batchpatch-authentication-in-domain-and-workgroup-non-domain-environments Make sure the necessary registry values were not removed/modified during the upgrade process

4. This link has some further WMI troubleshooting steps to try that are equally relevant for BatchPatch because in both cases it’s just a WMI connection that is being attempted, so it doesn’t matter if that WMI connection is being attempted from BatchPatch or from a different app, it’s still a WMI query being made in all cases: https://community.spiceworks.com/support/inventory/troubleshooting/advanced-wmi-issues

5. If you have any type of anti-virus or HIPS or similar security app running on the target, check that too as a possible culprit. However, generally ‘Access Denied’ is virtually always something specific to Windows permissions/authentication

6. See if you have the latest build of 20H2 or if there is an update available. You can manually/directly check for updates at the Windows Update control panel of the target computer

Thanks, I’ll try to talk about it, it’s weird that it happened to me on these specific computers. I have 250 PCs under management and on some, where Windows 10 – 20H2 is already running, BatchPatch works, so I’m confused here.
