Thanks. We'll let you know when a new response is added.

If this problem continues, I would look to see if there any other programs running in the background that can be turned off. Is this something new, if so what was the last software that was added? Does it seem to happen at startup more often? If so it could be background process doing their auto updates. It could also be related to your antivirus program and it’s scheduled scans and updates. Without doing the CTRL+ALT+DEL and seeing what app has the largest percentage of CPU time we can only make a few suggestions.

    What Windows version are you running now? What is your computer's specifications? For the time now, search for the word like, msconfig and after find it, open it, click Startup tab, and deselect all unnecessary startup programs other than windows related. Next click Services tab, select the checkbox Hide all Microsoft services and then deselect the services which are not necessary for now. (be careful).

    What OS are you running? What were you trying to do in file explorer when it stopped responding? Try doing a CTRL+ALT+DEL and end file explorer and try it again to see if the issue can be replicated.

    There is a lot that missing from the original question but that has been covered by others. When you do the CTRL+ALT+DEL and bring out the task manager it will display all the all the running processes. It may not actually be file explorer that is running the system to 100%, but some other process. I would look through the processes running to see what is actually causing the issue. Also if the system is badly fragmented and do not believe Microsoft's statement about Fragmentation the system indexer will use a lot of processing capability because the system has to hunt for where all the bits and pieces of a file are. Once you have determined what process is causing the issue then you can go back to the other steps either stop the process or removed the process from startup so it will not cause an issue. One other thing that may be causing the issue is that you have Malware / Viruses causing the issue, and they may be using up system resources. I would do a through scan of your system with some reputable products to remove anything that may be there.

    Sometimes some running programs are not ended up by click Ctrl + Alt + Del because of service is running background or shows Access Denied. In this case, you can start your system in Safe mode and try to close the running of background running programs that are really not necessary for now. Be careful about system's programs.

    For a better way, you can download/install Process Explorer (a small & free to use) and check what programs are slowing down your system. This is from Microsoft and please link here for more info: https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer
