Troubleshooting Win10 could not be installed. Net Framework 3.5 Prompt Error Code 0x800F081F

Win 10 was reinstalled once, but somehow it couldn't be installed. net framework 3.5 won't work even if you download the offline installation package.

Some people on the Internet say that they need to use win10's ISO file. I feel too troublesome. I share a very convenient operation here.

First, you need to download the cab version of the. net 3.5 file: Click Download

Download Zhihu, copy the file directly to Windows folder on C disk, and then open "Command Prompt (Administrator)" or "Wiondows PowerShell (Administrator)".

Enter the following command, and then press Enter:

dism /online /Enable-Feature /FeatureName:NetFx3 /Source:"%windir%"/LimitAccess

You must restart the computer once after the operation is completed, and then net 3.5 will be installed on your computer.

I use Win10 myself, so I can't guarantee that Win7 and Win8 can use this method. 0x800F081F
