I use Gmail, Google, Chrome, Candy Crush...

- Why does this update take so ridiculously long? And it's not the first one to do this. Most of the time the computer is on idle not doing anything. It's not frozen as the percentage will creep up every 30 mins. See this on many machines. There is no reason 1 update should take 8 to 10 hrs. Especially when most of the time the PC is doing nothing. Can install Windows 10 from scratch on a formatted drive in under 30 mins on a slow pc. Microsoft really drops the ball. These are clean business machines with very few apps installed. Maybe just office, QuickBooks and chrome.
Would you mind clarify your issue.
Do you mean, updating Windows installer was slower?
Or
After you installed updates, your PC becomes slower?
- Sorry but even i understood the issue
- Not sure what you means.
However, first we need to see if the performance is related to network or the computer or application and most users are not sure where is the performance issue. Slow loading of a website due to the website maintenance or slow system boot up are both performance issue but they are different issues.
Several stuff might lead to the performance issue and that is why I asked users to clarify the issue to identify the cause of it and guide the user correctly.
After installed updates(20H2) system became slow...
I have an old laptop with an AMD Dual-Core E-350 CPU... Now it idles at 30% plus of the CPU...

Check Windows Update and see if there is any other pending updates?
Take a look at:
Hello HuggySW,
Suggest you to run System File Checker scan:
1. Search for 'command prompt' using Cortana or Windows Search.
2. From results, right click on Command Prompt and select Run as administrator.
3. Type sfc /scannow command and press Enter key.
4. Let the command complete and then reboot the machine.
If issue still persists, perform clean boot:

See if it makes any differences.
- Hello, I faced the first problem.. While updating it took a whole night but it did update... I feel there is a problem with it... The laptop.. Can you clear this situation as to what happened?
- Try running Windows Update troubleshooter from Settings app > Update & security > Troubleshoot > Additional troubleshooters. See if it helps you. 

- I am fed up with these basic instructions for any symptoms? At the end just refresh and reinstall! Really? How many times?
