Best practices for resolving Zapp issues
The following programs have also been shown useful for a deeper analysis: ASecurity Task Manager examines the active Zapp process on your computer and clearly tells you what it is doing. A good Bantivirus tool detects whether the Zapp.dll file on your PC might be malware slowing down your system. Such unwanted programs are often not classified as viruses by other antivirus software and therefore go undetected.
A clean and tidy computer is the key requirement for avoiding PC trouble. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.
Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
To restore the original performance and remove unnecessary programs, you can 8reset your PC. Your personal files will remain intact, but any programs you installed will need to be reinstalled.
