Windows on ARM: Effective Workarounds for Slow Desktop Apps

Optimizing Windows on ARM performance requires specific adjustments to handle legacy software limitations.

Microsoft entered the ARM market in 2012 with the Surface RT, but that hardware failed to gain traction. Modern ARM laptops often struggle when executing older software because those programs rely on x86/x64 instructions. Translating these commands for ARM architecture creates significant performance overhead. Rather than waiting for developers to provide ARM64-native versions, users can implement specific configurations to improve their daily experience after six months of testing these methods.

Windows on ARM 11 utilizes a built-in emulator that defaults to power-saving modes. You can force high-speed operation to reduce launch times for x86 applications by 20-30%.

# View current setting
Get-ItemProperty -Path "HKLM\SYSTEM\CurrentControlSet\Control\PerfKeywordsStatistics" -Name "DisableFastEmuOnLowPower"

# Enable fast emulation even on battery
powercfg /setacvalueindex SCHEME_CURRENT SUB_PROCESSOR PROCFREQMAX 100
powercfg /setdcvalueindex SCHEME_CURRENT SUB_PROCESSOR PROCFREQMAX 100

WSL2 provides a superior environment for development tasks because ARM64 Linux binaries execute natively. Tools like Python, GCC, Docker Desktop, and Node remain responsive when kept inside the WSL filesystem rather than the Windows partition, which avoids slow cross-filesystem calls.

# Keep project files inside WSL for speed
mkdir ~/projects
cd ~/projects && git clone https://github.com/your/repo.git

# Access from Windows at \\wsl$\Ubuntu\home\user\projects

For software lacking ARM support, web wrappers or the "Install" feature in Chrome create pseudo-native experiences. Tools like Notion or Slack perform more reliably through these web-based methods than through emulation. You can explore these approaches at https://web2desk.app for more details.

Recompiling open-source software remains a viable final option. Rust users can enable native performance with a few commands:

rustup target add aarch64-pc-windows-msvc
cargo build --target aarch64-pc-windows-msvc --release

Go developers can achieve similar results by adjusting target environment variables.

I'm curious if this helps 32-bit apps or if it only fixes 64-bit software? You can actually boost performance for both by switching the emulator to high-speed mode via PowerShell: powercfg /setacvalueindex SCHEME_CURRENT SUB_PROCESSOR PROCFREQMAX 100.

My old Surface struggled too. Did native drivers fix the speed for you? That's because these apps are primarily designed for x86/x64, and converting those instructions for ARM chips leads to major performance hits. Don't wait for developers to rewrite them all as ARM64-native; I've been using a Windows on ARM daily driver for six months and have some effective workarounds. By default, Windows on ARM 11 translates x64 and x86 code using its built-in emulator, which is not fast. But you can switch it to high-speed mode instead of the default power-saving setting to make a real difference: # View current setting Get-ItemProperty -Path "HKLM\SYSTEM\CurrentControlSet\Control\PerfKeywordsStatistics" -Name "DisableFastEmuOnLowPower" # Enable fast emulation even on battery powercfg /setacvalueindex SCHEME_CURRENT SUB_PROCESSOR PROCFREQMAX 100 powercfg /setdcvalueindex SCHEME_CURRENT SUB_PROCESSOR PROCFREQMAX 100 Doing this shaved off 20-30% of the launch times for most x86 apps—it's not a miracle, but you'll definitely notice.

Frustrating stuff—did native ARM drivers actually fix the emulation lag for you? I’ve been running Windows on ARM daily for six months, and while native ARM64 apps are smooth, x86/x64 emulation still struggles because those apps weren’t built for ARM. The built-in emulator defaults to power-saving mode, but you can force it into high-speed mode with a quick tweak:

powercfg /setacvalueindex SCHEME_CURRENT SUB_PROCESSOR PROCFREQMAX 100
powercfg /setdcvalueindex SCHEME_CURRENT SUB_PROCESSOR PROCFREQMAX 100

That alone cut launch times by 20-30% for most legacy apps—still not perfect, but a noticeable improvement. For anything else, WSL2 with ARM64 Linux binaries is the real game-changer.
