Windows 10: Windows 11 pro refuses to talk to networked pcs

Windows 11 pro, updates all done everything power cycled. network sharing only works one way on machine. Windows REFUSES to allow access to fully shared files and computers on the network. Windows Claims that the machine/user is not granted access. but clicking the further help button only takes you to a WINDOWS 11 fluff page. Machine A: can see all machines and access all files shared on the network. Machine B: can see all machines on the network but is blocked from doing anything with them, in any way. Network reset did nothing at all only restarted the machine. Permissions: Guest, E

Unable to upgrade Windows 11 Home to 11 Pro

Thanks much, Dave, indeed it was a big job.

Clean install of Windows 11 from a bootable USB helped to Activate the Pro.

Just to summarize what was done:

1. Took backup of the drives and save some on cloud.
   
2. Installed the Media creation tool app as you suggested (https://www.microsoft.com/software-...t=Windows 11 Installation-,Media,-If you want)
   
3. Connected the USB and ran the application and downloaded the Windows 11.
   
   1. additional thing which I had to do is to install WLAN driver to the USB in advance, to have the WIFI option available as it was required to connect to a network to download the latest windows features while reinstalling the Windows, and Wi-Fi option was not available.
      
4. Turned off the 'Secure boot' from the BIOS menu.
   
5. Changed the 'Boot Order' in the BIOS menu to first use the USB Boot.
   
6. Saved and Exit, which triggered Restart and Windows installation.
   
7. During the network connecting stage to install the latest updates and features - 'Let's Connect you to a network', I opened the CMD (Shift + F10) and ran than WLAN driver exe to install it and then I was able to connect to my WIFI network.
   
   1. Optional to this step is to BYPASS the network connection stage by following this - bypass "lets connect you to a network" - Microsoft Community
      
   2. Then, doing that manually once Windows has been installed.
      
8. Once everything is set-up, I followed the suggestion from this again, and it worked - Unable to upgrade Windows 11 Home to 11 Pro - Microsoft Community
   

 

Ethernet network between 3 Windows 10 PCs problem

I performed your suggestions on my desktop (Win 10 Pro) and my laptop (Win 10 home) and left them running for about 30 minutes and I can now get a connection between the 3 PCs, I will perform your suggestions on my other PC (Win 10 Pro) and leave them all running for 30 minutes and hopefully that will connect .
I will report after I have done it.

 

I'm online from my wifi laptop but can't connect to my home network

Nope, I've tried all the steps of all the fixes listed by Dalchina and Try3 but the problem still exists. The W10 laptop refuses to access my main W7 pc (named CG16) on my home network, although it can 'see' it, ie, it shows CG16 in the network list. The only thing I haven't tried is Dalchina's suggestion about creating a shortcut, mainly because I'm not sure where this shortcut is supposed to be. I'm assuming it has to be on the W10 laptop but I don't understand how it could work. More info please, Dalchina, if you'd be so kind. Daymin, sorry: I have no idea what you're trying to say.
