Windows 10: Is W10's basic system image reliable to use today like in W7?

Thank you for reading and hopefully answering soon. :

W7 or W10

Hi everyone,

I have got W10 for a while. Now I have upgraded my PC. But, Lots of part of the motherboard / sound, graphic / can't work properly, because their drivers were writing for W7. Under W10 they just work on basic level. The issue about the compatibility makes lags
in games and in other type of usage. Now I would like to get back to W7 my pc. How can I do it? Obviously I am over the 10 days since upgrade. I, also, do not want to lose my works, software. Any suggestion? Should I buy a new HDD with W7?

 

W7 access of W10 share

On my home network W10 systems can access shares on other W10 systems, and W10 can access W7 shares. However, when W7 tries to access a W10 share, it wants a network password. I give it the user/pswd I use to log in on the W10 but that doesn't help.

I found one place:
Cannot access Shared folder in Windows 11/10, using Windows 7 PC
that suggested setting HKLM...Lsa\restrictanonymous to 1
but that didn't seem to help.

TIA!

 

Home Networks or Workgroups connecting W7 W10 systems

More test results:

W7: After creating a Home net group on W10 machine, the W7 machine stated, that there were no Home net group in the system and prompts me to create one. I expected in contrary an order to join one.

W10: After creating from new a Home net group on W7, W10 prompts me to join this one, but ending finally also in a "not found on system"

I removed both Home networks.

W7 explorer shows me the W10 machine, but could´nt access it.

W10 explore showed me the W7 machine, accessable and adding a legitimation for "everybody" on W7 allowed me to open a dataset in the W10 explorer.

Summary:

It was not possible by no means to connect a W10/W7 and a W7/W10 by a Home net group.

By the basic workgroup the W7 explorer showed me the W10 machine, but did´nt allow to acess it, the W10 explorer worked without problems with the W7 machines objects.
