Hello GordMcFee,
I understand that Spooler subsystem app is consuming too much of the CPU usage.
We appreciate your efforts in troubleshooting the issue and providing us the detailed information about the issue.
Spooler subsystem App is a process that helps manage the printer & fax systems. Whenever a program sends a document to the printer, the
spooler subsystem app adds it to the print queue. The Print Spooler service saves these print jobs in memory and sends them to the printer one by one when the printer is available.
Method 1:
Step 1: Uninstall Printer
I suggest you to uninstall and reinstall the printer. You can refer to the article on how to
uninstall HP Printer Software (Windows)
Step 2: Install Printer
I suggest you to download drivers from the printer manufacturer’s
website and refer to the article on how to Install a printer in Windows 10.
**Method 2:**I suggest you to perform a full system scan using the
Microsoft Safety Scanner
Note: Microsoft Safety Scanner is a scan tool designed to find and remove malware from Windows computers. Download it, run a scan to find malware and try to reverse changes made
by identified threats.
Hope it helps.
Regards,
Zaki
