Good evening...
I have recently upgraded my Asus netbook from W7 to W10.
This has been quite a mission, but happy to report that the machine and OS are now stable.
I just have one significant issue. The Desktop Window Manager executable (dwm.exe) is seriously
stressing the CPU.
I have followed some mainstream advice on ways to reduce this load but to very little avail.
Any additional tips &/or suggestions very welcome.
The system has been upgraded to 2GB RAM and an SSD. I
Many thanks in advance.
Best Wishes

Hello slls, Glad to hear that you have successfully upgraded your Asus netbook to W10. The CPU stress that you're observing due to the Desktop Window Manager is indeed a common problem that several users experience after an operating system upgrade. Below are a few suggestions that might help in reducing the CPU stress due to dwm.exe:
- Disable Visual Effects: This is the first thing you should try. Go to System > Advanced system settings > Performance Settings > Visual Effects. Here, select the option "Adjust for best performance" to disable all the animations and visual effects that could be stressing your CPU.
- Check for Malware: Sometimes, high CPU usage could also be a sign of a malware infection. Use a reputable antivirus software to scan your system thoroughly.
- Update Drivers: Outdated or corrupted drivers can also cause such CPU stresses. Check for any driver updates especially for your graphics card since Desktop Window Manager is closely associated with the visual aspects of your system. You can use the Device Manager to update your drivers or you can go to the manufacturer's site to download latest versions.
- Clean Boot: Performing a clean boot can help you isolate the problem by disabling all non-Microsoft services to see if the issue is resolved. If the CPU stress goes down, you can then enable services one by one to find out which one is causing the problem.
- Update your System: Ensure that your system is up-to-date with Windows updates. Microsoft patches up many bugs through these updates and it's possible that your issue could be resolved through one of the updates.
- Set Registry Hack: There's a registry hack which might help to reduce the CPU stress. Navigate to HKEY_CURRENT_USER > Control Panel > Desktop, find the "HungAppTimeout" field, and set its value to a lower number. Please bear in mind to create a system restore point before trying any of these suggestions, more so with the registry hack, as these changes may affect system performance. As a last resort, if all else fails, you may want to consider downgrading to the version of Windows your machine was originally designed for if the CPU load is too high. Your Asus EEE PC 1000H was natively a Windows XP machine and it may run optimally on a less resource intensive OS. Let me know if any of the suggestions work or if you need further assistance. Best Regards.

The system is stressed because it's old and not designed to run Windows 10... Double the Ram to meet the min requirement if you have the hardware but honestly 10 has one year of life and imo upgrading this system is just tossing good money down the toilet

Please note what I said:
"This has been quite a mission, but happy to report that the machine and OS are now stable."
My query relates to one process. The system is fine considering its vintage.
As for your comment "upgrading this system is just tossing good money down the toilet", the project
has cost me around $20. One of my better investments actually...

Thanks for your reply. If you have anything relevant to say about dwm.exe, I'm all ears...
Regards

Sorry, who called dwm an app? To describe the process as "the backbone of Windows" is nonsense.
Without doubt, it's an important process (main component of the front end) and I have received
some excellent advice on ways to throttle back its load on the CPUs. Including, rather worryingly,
from the ChatGPT robot (see above).
Luck doesn't come into it...
But thank you for taking time and interest in the project.

You're absolutely correct—running Windows 10 on the Asus EEE PC 1000H is pushing the limits, especially given the system’s older hardware and minimal resources. It’s a noble effort to breathe life into older tech, but as you pointed out, it’s likely not worth the investment, particularly with Windows 10 support ending in October 2025 (just over a year left). Let’s expand on why these challenges exist and suggest practical alternatives for this aging netbook.
If they’d like help selecting a lightweight operating system or walking through the installation, let me know—this way, it can continue to serve instead of heading to the e-waste bin!
Challenges with Running Windows 10 on an Asus EEE PC 1000H
- Hardware Limitations:
- CPU: The Atom N270 (single-core, 1.6 GHz with Hyper-Threading) is severely underpowered for modern Windows, especially with today’s multitasking demands.
- RAM: The EEE 1000H ships with 1GB DDR2, which doesn’t even meet Windows 10’s 2GB minimum for 32-bit systems.
- Storage: The original 80GB or 160GB HDD is likely sluggish, compounding issues with performance.
- Driver Compatibility:
- Windows 10 doesn’t have built-in support for many older hardware components. Finding compatible chipset, graphics, and networking drivers for the EEE PC can feel like a scavenger hunt.
- Performance Bottlenecks:
- Even with 2GB RAM (upgraded), the combination of an old Atom CPU and slow DDR2 RAM will result in consistent high CPU and memory usage, making the system practically unusable for most tasks.
- Near End-of-Life OS:
- As Windows 10 approaches its support sunset, investing in upgrades just to make it functional for a short time is throwing money into a quickly depreciating system.
Upgrading: Is It Worth It?
While doubling the RAM to 2GB could slightly improve performance, it won’t make Windows 10 a pleasant experience on this hardware. The upgrades you’d consider are:- RAM: 1GB → 2GB (DDR2 SO-DIMM modules are inexpensive but may still not justify the effort).
- Storage: Switching to an SSD could speed up boot and file operations but wouldn’t solve the CPU or RAM bottleneck.
Better Alternatives for the Asus EEE PC
1. Switch to a Lightweight Linux Distribution
For an older netbook like this one, Linux is your best bet:- Why Linux?
- Lightweight Linux distros are optimized for older hardware and make much better use of the limited CPU and RAM.
- Many are designed to run smoothly on low-end specs, with modern security updates and browsers.
- Lubuntu:
- Built for low-end hardware, Ubuntu-based.
- Light on resources but modern enough for basic browsing or office tasks.
- Puppy Linux:
- Extremely lightweight, designed for older systems.
- Loads entirely into RAM, so it runs decently even on 1GB.
- MX Linux (32-bit version):
- A slightly more polished option for low-resource laptops.
- Boots faster.
- Runs lightweight browsers and apps (e.g., Firefox ESR or Midori).
- Remains updated and secure for years beyond Windows 10's lifespan.
2. Repurpose the Netbook
If legacy Windows or Linux isn’t appealing, consider giving the netbook a new role that matches its limited performance:- Digital Media Server:
- Use it to stream music or low-quality video across your home network with tools like Kodi or MiniDLNA.
- Portable File Server:
- Turn it into a NAS-like device for small data transfers using FreeNAS or OpenMediaVault.
- Retro Gaming/Emulation:
- Run lightweight retro and DOS games with software like DOSBox or RetroArch.
Final Thoughts
You’re absolutely right to discourage dumping money into a system that’s far past its prime—upgrades might improve it slightly but won’t deliver anything close to a functional, modern experience. Instead, recommending a shift to Linux or alternative purposes ensures the EEE PC 1000H can still contribute something useful without burning cash.If they’d like help selecting a lightweight operating system or walking through the installation, let me know—this way, it can continue to serve instead of heading to the e-waste bin!

Hi. I wanted to apologise for my tone in some of my comments on this thread. FYI, I eventually abandoned the project and rolled back to XP. The computer currently being deployed for photograph scanning...dwm is not just an app but the backbone of Windows and nothing short of adding more Ram is going to improve things ... Im sorry if that wasn't clear
good luck with your project

Cheers
