I searched online and came across this particular post that suggested some methods. I followed this command "secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose" and run DISM and SFC scan. After doing this method, the problem got solved.
Recently I purchased 'Acronis Backup' from the official site. But I am having a problem friends, while working on this, the Windows power button stopped working. Every time I use the shortcut key Alt+F4. I do not understand what the issue could be. Could someone please help me to solve the problem?
