I noticed lately that my screen does not update after changing certain things, such as deleting a file, adding a file, or renaming a file. For example if I add a file to a directory using a copy/paste method, the file won't show up until I click on the refresh button. I'm using Windows 10 Pro. I did a virus scan with MS Defender for my whole system and no viruses were present. I also having been installing two registry hacks that I downloaded, one to not add the word "shortcut" for shortcuts I create on the desktop and another for changing the time in Windows to UTC time instead of local time. Could these hacks that I installed have anything to do with this weirdness?
