vincej, 1. Go to the desktop, right click anywhere, hover your mouse over new and then click shortcut2. When you are making a shortcut it will ask you to type a location. type in "msconfig", click next and then it will ask you what you want to name the shortcut name it anything you want its not imprtant.3 . A shortcut for msconfig will show up double click it and click on the boot tab at the top. once in the boot tab enable safeboot and the click network underneath it and then click apply then OK it will ask if you want to restart you should restart it4. Once it is restarted you should go to msconfig again and then turn off safe boot and the apply and restart again and hopefully once you have done that things should return to normal
I recently had to reinstall windows 10 to a new SSD on my Dell Inspiron Laptop. I added the recommended drivers through the Dell website  Problem:  Suppose I have 3 apps open. Their icons are on the task bar and the icons are underlined denoting they are open.  Prior to the new install, I could click a taskbar icon and the app would come to the top. Now it does not do that. The app currently open and on top stays there.  Similarly, if I use Atl+Tab selecting an alternative app does not bring it to the front.  Similarly if I have 2 apps on the screen and I click on the app at the back, it does not come to the front.  How can I fix this ?  Many thanks !!
