First off, I am running Windows 8 on my Dell desktop, 64 bit and it's only 3 yrs old. It has been restored to factory condition only 3 months ago. Every since then I have had problems with updating my PC. I get this pop up every 15 seconds or so that tells me to go check for updates, when I do that it just runs and runs and runs but never finds the updates. This is so frustrating. I have tried every possible solution I could find, but nothing helps. I have tried refreshing, restoring, system restore but my PC says it is unable to perform these tasks. I have tried command prompts, to Restore health but it tells me The component store has been corrupted and it is repairable, but doesn't tell me how to fix it. I tried the command prompt sfc /scannow and it comes back as Windows Resource Protection could not perform the requested operation. My PC restarts itself quite often saying it has ran into a problem and needs to restart itself, the error message is usually System Service Exception or Kernel Security Check Failure. I could go on, but this is rnough for now. If there is anyone out there who can help please, I am willing to try anything to get this problem fixed ASAP!!
