Windows 10: Two issues both related to certificates on Win 7

I have two issues both related to certificates and perhaps both have common reasons I need to find out. The first and les important issue is when I try to open any website via https in chrome browser v103, I receive the error NET::ERR_CERT_DATE_INVALID. However, date and time on my laptop are set correctly. The second and more important issue is when I try to install Zoom app for meetings v5.11.1 or the latest version 5.11.4, I receive the error 10003 and their support team said that the error is caused by certificates. They recommended to follow the instructions to install their certificat

Win 7 and Win 10 on network

I have home network with separate modem, router, and WAP's. My Windows 7 computer does NOT list the Windows 10 computers on network computer list but the Windows 10 computers network list DO list the Windows 7 computer.

Turned off firewalls, gave permissions, shared drives. Nothing allows Win 7 computer to access the Win 10 computers.

Any suggestions for a fix?

 

Lumia 1020 running Win 8.1 is not detected by my desktop (Win 8.1) and laptop (Win 7)

Hello,

Since 2-3 weeks now, I have not been able to connect my Lumia 1020 phone to either of my machines (Win 8.1 and Win 7). Not sure what changed with either of the devices in the meantime.

I have a Lumia 1020 with the following configuration:

- Carrier: AT&T

- Software: Windows Phone 8.1 Update

- OS Version: 8.10.14203.306

I've tried:

- Steps listed in here:
http://support.microsoft.com/kb/2749484 but with no success.

- Soft-resetting the phone but to no avail.

- Turning the phone all the way off. Connected the phone to the PC but drivers did not load

- Running Microsoft FixIt tool

- Steps listed in several other communities related to other users having similar problem with their Win 8 phone

Also, I do not see my phone name listed under System information. It shows my phone as an Unknown USB Device with an Exclamation mark.

Any suggestions/help?
