1] Uninstall KB5006670 Cumulative update (din control panel, updates, sau linie de comanda admin wusa /uninstall /kb:5006670 )

2] Run Printer Troubleshooter msdt.exe /id PrinterDiagnostic

3] Disable the Windows 10 managing Printers automatically

4] Configure PointAndPrint registry (cmd as admin, reg add “HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\Printers\PointAndPrint” /v RestrictDriverInstallationToAdministrators /t REG_DWORD /d 1 /f )

5] Use the Registry Editor (

Click on the Start button and type “Regedit” from your keyboard.
Select the Registry Editor application from the best match.
If UAC prompts on the screen, click on the Yes button to give your permission.
In the Registry Editor window, navigate to the path – 

HKEY_CURRENT_USER\Software\Microsoft\WindowsNT\CurrentVersion\Windows

Move to the right pane and double-click on the Device option.
In the popup menu, give the name of the printer inside the Value Data field.
Clicking on the OK button, a new error may appear saying – “Cannot edit Device: Error writing the value’s new contents”.

To connect our 380v tri motor in 220v mono (phase + neutral), we will use the triangle coupling.
We will connect for example: the phase in “u”, the neutral in “v”, and it will be necessary to add a capacitor between “v” and “w”
Very important !The capacitor must have a voltage greater than 230V and must be AC ??~, NEVER use a polarized capacitor otherwise it will explode!The usual value of the capacitor is expressed in micofarad “µf”
To find its value it is enough to multiply the power in CV by 50.
Example: a 250w motor (0.25kw)

to begin, you have to convert Watts into horses. for this we divide the watts by 736 (1 CV = 736 W)
In our example 250/736 = 0.34 HP, our engine is 0.34 HP.
To find the value of the capacitor: 0.34 x 50 = 17, so to operate the motor of 0.25kw requires a capacitor of 17 μf.
If the value of the capacitor is less than 17 μf, the motor will work much worse, or not at all.If the value is greater than 17 μf it is not annoying at all.

Choose Run and write regedit.

Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion

Change the keys EditionID and ProductName.

EditionID can be found in your Windows 7 installation CD under sources\ei.cfg.

ProductName will be shown when you try to install and are denied:

Windows 7 Ultimate cannot be upgraded to Windows 7 Home Premium

Here the Windows 7 Home Premium is the ProductName.

Make sure that it matches exactly.

This procedure worked like a charm for me!

In the BIOS, i went change the SATA to IDE mode (NOT RAID, NOT AHCI)

1.Boot Win7 DVD

2.Choose the Language Selection.

3.Choose Repair.

4.On the recovery tools choose the Command Line Console

5.Type:regedit <ENTER>

7.Highlight HKEY_LOCAL_MACHINE

8.File > Load Hive

9.Select < windows partition with problem > \Windows\System32\config\system (Backup this first, it’s advised)

10.Regedit will ask for a Key name: Name it something like “temp”

11.Located HKEY_LOCAL_MACHINE/temp/Select/Current

12.Searched for every key containing the value “SCSI Miniport” where the “Start” value was a “3” and changed the “Start” value to a “0”. (F3 to search next result).

13.Highlight “temp”

14.File > Unload Hive

15.Restart

16.Enter in Win7 🙂
