This problem just started but is causing a severe work stoppage. Once my computer is up and running it appears there is a program running in the background that causes my mouse, keyboard, and any program to stop working. I have to relocate my mouse to the location on whatever document I was working on. When I open TasK Manager it shows  multiple sessions of wermgr.exe in process. I tried to close the application but cannot. I tried recommended fix from 2012 but it didn't work. I can only type about 3 or 4 words at a time before I lose my mouse. So very frustrating. I do not get any error  messages. Please help!!!

To trouble shooting this issue, since this issue might occurs if you have problem program runing as startup, Check startup program on your computer and try disabling them one-by-one (or using clean boot as mentioned by S.Sengupta). If it suddenly works, you have found the problem program.
