I would go to your windows update and see the updates and find that 4.8 net framework and uninstall it.Do a restart and see if that fixes it. If it does then you know what you don't want in the computer. I would also make sure that future updates not be allow to be downloaded but let you decide witch ones to install. that way you can select other downloads that don't have anything to do with the 4.8 net framework. Also you might check out windows update and see if maybe they know about the bug and maybe a fix for it. By now they may already have a patch for it. Thats the best ideas i have. Hope you can get it fixed. Windows can be buggy sometimes. Sometimes they push the upgrade before they debug the update. Thats when this kinda stuff happens. Hope you can fix it and i just had another idea. Try and do a system restore and see if there is a restore point to just before that update went in. Not sure what else i can give advice to. Good Luck an let us know how it goes.wd
