Question Windows Apps Slow, computer is fine?

[Blurrza]

Windows 10 has recently slowed down to a crawl involving only system related actions. For example;

• Launching an .exe file will freeze whatever window I attempt to launch it on for up to 30+ minutes before finally launching. If launching at all. This includes the windows explorer and browsers such as Firefox/Chrome.
• Booting and logging into the computer can take upward to 20 minutes, but computer runs smoothly once logged in.
• Windows related Apps like Mail will no longer load emails received at all, and will simply load infinitely.
• Windows Update takes a long while to detect any required updates needed, it took me two tries and a restart to get it to show anything at all.

Everything else is fine, the computer itself doesn't lag at all with internet browsing, gaming, watching videos, etc. This is why I did not notice an issue until attempting to download an executable file. I tried troubleshooting but couldn't find my exact issue anywhere, and the solutions I did attempt did nothing. This includes:

• Updating Windows (how I learned it was being slow)
• Restarting computer
• Running Virus Scan (Avast/Malwarebytes)
• Editing Registry (as suggested in several posts I read)
• Running a Scan through cmd (sfc /scannow)

Other than Windows itself and Windows Store related Apps, nothing else seems effected?
