Windows 10: How to fix Error Code 0x800F081F when installing .NET Framework 3.5


When you select to install .NET Framework in the Windows Features list in the Control Panel, it does not complete. After asking if you’d like to use Windows Update, it then gives you an error code 0x800F081F


  • Insert Windows 10 installation CD or mount the ISO
  • Open an administrator command prompt
  • Type the following command (substitute correct drive letter)
    Dism /online /enable-feature /featurename:NetFx3 /All /Source:D:\sources\sxs /LimitAccess

Fixing Windows 10 “printer is in error state” when connected via parallel port


You’ve just installed or upgraded to Windows 10, and your printer connected via parallel port refuses to work, giving an error message saying “printer is in error state”.

Solution #1:

Go to the device manager, find the parallel port and double-click it to bring up the properties sheet.  Click the “Port Settings” tab and then select “Use any interrupt assigned to the port” and click OK (see Figure 1 below).  The printer should be detected and work properly.

(Update on 09/27/2017) Solution #2 :

In some cases, solution #1 seems to work but the problem returns when the computer is rebooted.  In that case, changing the setting described above back and forth will cause it to work again, but only until the next reboot. After a significant amount of time troubleshooting this on a few computers, we’ve concluded that Windows 10 just doesn’t print reliably with parallel ports.  In stubborn cases like this, we’ve resorted to getting a StarTech USB-to-parallel cable, which essentially makes the printer look to Windows like a USB printer. In all the cases we’ve ran into, that has always solved the issue permanently. However, the brand of cable could make a difference. We used a TrippLite cable in one situation like this and it did not work, but the StarTech cable has worked every time.
