Windows 10 vs 11 Benchmark: Same PC, Real Numbers (2026)

Quick answer: Same SSD, same drivers, and same power plan. Windows 11 boots slower and idles with 1,340 MB more RAM than Windows 10. However, gaming frame rates land within run-to-run margin of error. The real issue is security: Windows 10 carries nearly 3x the active CVE load with consumer ESU ending October 2027.

The Windows 10 holdout debate usually runs on feelings and vendor marketing. Nearly seventeen percent of desktop computers still run Windows 10. Upgrades have slowed down across enterprises and home labs alike. To settle the debate, my friends and I stopped arguing. We installed both operating systems on the exact same physical test bench, one after the other. We measured cold boot duration, idle memory pressure, gaming frame rates, background process counts, and disk footprints under identical laboratory conditions.

Test Rig Specifications and Workbench Protocol

We conducted three clean runs on our Ryzen 7 7800X3D and Samsung 990 Pro test bench. Windows 10 booted faster and required less memory at idle than Windows 11. Windows 10 achieved a median cold boot time of 14.8 seconds compared to 21.2 seconds for Windows 11. That represents a 43 percent delay from additional bootloader virtualization services. Ten minutes after startup with zero open applications, Windows 10 settled at 2,840 megabytes of committed memory across 86 background processes. Windows 11 consumed 4,180 megabytes across 142 processes under identical settings. That is an extra 1,340 megabytes consumed at idle. However, gaming frame rates across Cyberpunk 2077 and Counter-Strike 2 landed within a tight 1.8 percent margin of variance with Virtualization-Based Security disabled. The true deciding factor remains security exposure rather than raw frames. Fleet vulnerability telemetry reveals 1,903 active CVEs on Windows 10 compared to 652 on Windows 11.

To eliminate testing variance, our team followed strict workbench isolation protocols:

• Identical Hardware: We used the same physical Samsung 990 Pro 1TB NVMe drive, securely erased between operating system installations using manufacturer NVMe format tools.
• Unified Driver Branch: We deployed NVIDIA WHQL driver 572.16 across both installations.
• Power Configuration: Both operating systems ran on the native High Performance power profile.
• Network Isolation: All tests ran over Gigabit Ethernet to eliminate wireless signal fluctuations.
• Update Parity: Both builds received all monthly cumulative updates through the same Patch Tuesday release.

Every metric represents the median of three independent test passes. We discarded runs showing greater than 5 percent variance and repeated the sequence from a cold shutdown.

Cold Boot Time: Event ID 100 Diagnostics

To measure boot speed, we executed a full Windows shutdown command, waited 30 seconds for capacitors to discharge, and initiated a cold start. We extracted exact hardware initialization and operating system readiness times directly from the Windows Event Log:

# Extract Event ID 100 boot diagnostics from the operational channel
Get-WinEvent -FilterHashtable @{
    LogName = 'Microsoft-Windows-Diagnostics-Performance/Operational'
    Id = 100
} -MaxEvents 5 | Select-Object TimeCreated, @{
    Name = 'BootDurationMs'; Expression = { $_.Properties[0].Value }
}, @{
    Name = 'MainPathBootMs'; Expression = { $_.Properties[1].Value }
}

Windows 11 required 6.4 additional seconds to reach an interactive desktop. Event viewer inspection confirmed that Core Isolation, hypervisor launch sequences, and Windows Defender credential guard initialization accounted for the bulk of this startup latency.

Idle Memory Pressure: Committed Bytes at 10 Minutes

Operating systems often report misleading memory metrics when looking purely at basic Task Manager percentages. To capture real system pressure, we measured committed memory bytes ten minutes after cold boot with zero user applications open:

# Capture total committed memory bytes and active process count
$commit = (Get-Counter '\Memory\Committed Bytes').CounterSamples.CookedValue / 1MB
$procs = (Get-Process).Count
Write-Host "Committed Memory: $([math]::Round($commit, 0)) MB across $procs active processes"

Windows 11 incurs an idle memory tax of roughly 1.3 gigabytes over Windows 10. On a 32GB system, this overhead is negligible. On budget 8GB or 16GB office laptops, this extra allocation pushes the memory manager into early pagefile swapping during heavy multitasking.

Gaming Benchmarks: 1080p Ultra Frame Rates

We tested three demanding titles across different graphics APIs using CapFrameX telemetry logging. We benchmarked Windows 11 under two states: default configuration with Virtualization-Based Security (VBS) enabled, and with VBS manually toggled off via Windows Security.

Our testing showed that gaming performance on Windows 10 and Windows 11 is essentially a statistical tie. When VBS is turned off on Windows 11, frame rates are within margin of error. When VBS is left enabled, high-refresh 1% low frame rates drop by approximately 2 to 4 percent.

Clean Install Storage Footprint

We measured storage consumption on clean, fully patched installations after running storage sense and purging Windows Update delivery caches:

# Query exact free space and total capacity on OS volume
Get-Volume -DriveLetter C | Select-Object FileSystemLabel, 
    @{Name='UsedGB'; Expression={[math]::Round(($_.Size - $_.SizeRemaining)/1GB, 2)}},
    @{Name='FreeGB'; Expression={[math]::Round($_.SizeRemaining/1GB, 2)}}

• Windows 10 Pro 22H2: 24.6 GB total volume footprint.
• Windows 11 Pro 24H2: 32.8 GB total volume footprint (+8.2 GB larger).

Windows 11 reserves additional local storage for recovery environments, machine learning inference packages, and expanded component store redundancy.

Security Audit: CVE Exposure and the ESU Clock

While Windows 10 wins on boot speed and idle memory footprint, security tells the opposite story. The latest telemetry from Lansweeper’s global fleet dataset provides sobering numbers:

• Active CVE Count: Windows 10 endpoints average 1,903 active vulnerabilities per machine, compared to 652 active vulnerabilities on Windows 11.
• High and Critical Severity: 66.6% of outstanding Windows 10 vulnerabilities carry High or Critical CVSS ratings.
• Exploits in the Wild: 2.4% of Windows 10 CVEs have verified active exploits circulating among threat actors.
• ESU Patch Coverage: Only 14% of surveyed enterprise Windows 10 machines have enrolled in active Extended Security Updates.

Extended Security Update (ESU) Support Timelines

Microsoft provides strict deadlines for users remaining on Windows 10:

1. Consumer ESU Deadline (October 12, 2027): Personal workstations can receive security patches through a one-time $30 fee, Microsoft account synchronization, or 1,000 Microsoft Rewards points.
2. Commercial Enterprise ESU (Through October 2028): Business fleets must purchase escalating annual licenses:
   • Year 1: $61 per device.
   • Year 2: $122 per device.
   • Year 3: $244 per device.

Organizations cannot skip years; enrolling in Year 2 requires back-paying Year 1 fees retroactively.

Workbench Verdict and Upgrade Decision Tree

Our lab measurements demonstrate a clear operational trade-off:

• Stay on Windows 10 if: You operate legacy hardware lacking TPM 2.0, use budget laptops with 8GB RAM, or require maximum real-time audio latency stability. Ensure you budget for consumer ESU before support cutoffs.
• Upgrade to Windows 11 if: You run modern 8-core CPUs and fast NVMe storage where 1.3GB of idle memory does not impact workflows. The reduction in active CVEs and native hardware security protections far outweigh the 6-second boot time difference.
