It is high time to report my experiences with the W10 installation to you. Microsoft pushes all of us to do this before end of June.
1. Do a thorough backup of all your data.
2. If you use the attached file, and invoke it, it does the whole job by itself. You can go and do other things in the 2-4 hours the program is busy for you.
At last you have an upgraded PC with all your files and nearly all settings as they were. This is really neat, a big achievement by MS.
3. I had to delete and reinstall the anti virus program.
3. Everyone nowadays works with a router; it contains a firewall. I strongly suggest you disable the W10 Firewall and Defender, if you use a third party anti virus.
4. The biggest problem, I had, was the LAN networking. My experience is, very few people use this feature; it allows pulling/pushing files from/to other computers.
I could not see all computers under "Network". W10 became became suddenly very taciturn about the malfunction.
W10 tries you to use their stupid Library system with the so called Homegroup; I prefer a Windows C disk for programs and a Data D disk for your data files.
It took me some time to see that they use 2 kinds of networking and synchronizing. W10 sets up a Workgroup, constituting the old LAN networking.
On top of this they want you to set up the Homegroup; they want you to join it. Don't do that, it prevents the Workgroup to function properly. MS's idea is to synchronize the Libraries among the LAN computers. So at last I disabled ("unjoined") homegrouping at every PC in the network.
5. If you use a Hebrew keyboard, it has to be added manually.
6. The vast 3-4 GB file C:\Windows.old can be deleted. Recommended.
7. A few words about log in, user name and password. Always has been a nuisance. I hate all these passwords, but I also have a key on my front door. So it is apparently needed in this world. You can, though, remove the W10 log in procedure, as follows:
Open the Run command box (Start > All apps > Windows System > Run or press Windows key + R). In the text box, type netplwiz and press Enter.
A User Accounts window will open. Under Users for this computer: select your username and then uncheck the box next
to Users must enter a user name and password to use this computer. ClickApply.
A new window labeled Automatically sign in will pop up. Type your password twice and then clickOK.
Your computer will now bypass the log-in page when you turn on your PC.
So, this is it folks. W10 works nicely, I can recommend it with my conscience at ease.
