Some people on the Internet say that they need to use the ISO file of win10. I feel that it is too troublesome for me to share a very convenient operation here.
First, you need to download the. NET3.5 file in cab: click download
Download haozhihu, copy the file directly to the windows folder on Disk C, and then open the command prompt (administrator) or “windows PowerShell (administrator)”.
Enter the following command and press enter:
dism /online /Enable-Feature /FeatureName:NetFx3 /Source:"%windir%"/LimitAccess
After the operation is completed, you must restart the computer, and then. NET3.5 will be installed on your computer.
I use win10 myself. I can’t guarantee that win7 and win8 can use this method. 0x800F081F
The above is the solution that win10 can’t install. Net Framework 3.5. The error code is 0x800f081f. I hope it can help you. If you have any questions, please leave me a message, and the editor will reply you in time. Thank you very much for your support to the developeppaer website!
