MIcrosoft didnt learn-NO SOUND AGAIN after major update in windows 10-64 home!!!

after yesterdays-this mornings update-i triggered it. again no more sound!!
must go back then like beforehand- see other thread.

I was right. working again. has to wait a bit. intel wanted to install a graphic room.dont know if it could be installed. i went to shop. maybe one must leave the machine alone and wait.

intel wanted to install a graphic room.dont know if it could be installed. graphic room installed. went to it and they tell old version must be removed. forget its name.

Again sound disappeared after windows updata. Now i had the idea of resetting Windows. For the first time in 4 years! WORKED. Problem solved. Sound available.
Winxp-Netframework reinstallation helped.
Earlier in Winxp-times i remember deinstallation of netframework(all versions?) and reinstalling automatically solved many problems.
