Software Center High CPU Usage

Fix Software Center consuming excessive CPU resources and causing system performance issues. Stop the slowdown and optimize performance.

Quick CPU Usage Check

First, let's confirm Software Center is actually causing high CPU usage:

  1. 1. Press Ctrl + Shift + Esc to open Task Manager
  2. 2. Click the "Processes" tab
  3. 3. Look for "Software Center" or "SCClient.exe"
  4. 4. Check the CPU column - high usage is typically 25%+ constantly
  5. 5. Note any other SCCM-related processes with high usage

Why Software Center Uses High CPU

Background Activity Issues

  • • Continuous policy refresh loops
  • • Large software download in progress
  • • Multiple installation queue processing
  • • Inventory collection running
  • • Software metering processes

System & Configuration Issues

  • • Corrupted SCCM client installation
  • • Network connectivity problems
  • • Conflicting antivirus software
  • • Insufficient system resources
  • • Outdated SCCM client version

Immediate Actions to Reduce CPU Usage

Emergency CPU Reduction

If Your Computer Is Severely Slow:

  1. 1. Close Software Center - End the Software Center process in Task Manager
  2. 2. Pause downloads - If downloads are in progress, they may continue in background
  3. 3. Restart SMS Agent Host service - This stops all SCCM background activity temporarily
  4. 4. Wait 5 minutes - Allow system to stabilize before reopening

Note: This is a temporary fix. The underlying cause still needs to be addressed.

Detailed Solutions by Cause

Solution 1: Stop Runaway Background Processes

Sometimes SCCM processes get stuck in loops, consuming CPU continuously.

Steps to Reset Background Processes:

  1. 1. Open Task Manager and end "Software Center" process
  2. 2. Press Windows + R, type services.msc
  3. 3. Find "SMS Agent Host" service
  4. 4. Right-click → "Stop"
  5. 5. Wait 30 seconds
  6. 6. Right-click → "Start"
  7. 7. Wait 2-3 minutes before opening Software Center

Success rate: ~80% for process-related high CPU usage

Solution 2: Clear and Reset Cache

Corrupted cache files can cause SCCM to work inefficiently, consuming more CPU.

Clear SCCM Cache:

  1. 1. Close Software Center completely
  2. 2. Stop SMS Agent Host service (see Solution 1)
  3. 3. Navigate to C:\Windows\ccmcache
  4. 4. Delete all contents (you may need admin rights)
  5. 5. Navigate to C:\Windows\CCM\Logs
  6. 6. Delete all .log files older than 7 days
  7. 7. Start SMS Agent Host service
  8. 8. Open Software Center and test

Effect: Forces SCCM to rebuild cache and policies cleanly

Solution 3: Adjust SCCM Client Settings

Modify client settings to reduce background activity frequency.

Reduce Background Activity:

  1. 1. Open Software Center
  2. 2. Go to "Options" tab
  3. 3. Set "Computer maintenance" to off-hours
  4. 4. Reduce "Business hours" range if possible
  5. 5. Disable automatic software downloads if not needed
  6. 6. Set "Wake computer" options to never during busy times

Note: Some settings may be controlled by IT policy and can't be changed

Solution 4: Check for Conflicting Software

Antivirus and security software can conflict with SCCM, causing high CPU usage.

Common Conflicts to Check:

  • • Antivirus real-time scanning - Add SCCM folders to exclusions
  • • Windows Defender - Exclude C:\Windows\CCM and C:\Windows\ccmcache
  • • Third-party security tools - Temporarily disable to test
  • • System optimization software - May interfere with SCCM processes
  • • VPN clients - Some can cause connectivity loops

Add Antivirus Exclusions:

  1. 1. C:\Windows\CCM\*
  2. 2. C:\Windows\ccmcache\*
  3. 3. C:\Windows\ccmsetup\*
  4. 4. Process: ccmexec.exe
  5. 5. Process: SCClient.exe

Advanced Diagnosis

Checking SCCM Logs for CPU Issues

Key Log Files to Check:

  • • SCClient.log - Software Center activity and errors
  • • AppEnforce.log - Application installation processes
  • • PolicyAgent.log - Policy refresh and processing
  • • CcmExec.log - Main SCCM client service activity
  • • LocationServices.log - Network and server communication

What to Look For:

  • • Repeated error messages every few seconds
  • • Failed connection attempts in loops
  • • Policy refresh failing repeatedly
  • • Download or installation processes stuck
  • • Database or WMI access errors

Long-term Performance Optimization

System Optimization

  • • Keep Windows and SCCM client updated
  • • Ensure adequate free disk space (15GB+)
  • • Close unnecessary applications while using Software Center
  • • Schedule software installations during off-hours
  • • Use wired network connection when possible

Maintenance Tasks

  • • Clear SCCM cache monthly
  • • Restart SMS Agent Host service weekly
  • • Monitor Task Manager for unusual CPU spikes
  • • Report persistent issues to IT promptly
  • • Keep antivirus exclusions updated

When to Contact IT Support

Contact your IT department if:

  • •CPU usage remains high (>50%) even after trying all solutions
  • •Software Center causes system freezing or BSOD crashes
  • •High CPU usage started after recent SCCM client update
  • •Multiple users in your organization report similar issues
  • •You need the computer for urgent work and can't wait for gradual fixes
