Windows 10 Upgrading and House Cleaning at the Same Time

[DennisOS2]

I have a 8yo Dell Optiplex 9020 with a new Samsung SSD 870 EVO HD. Win10 and all the apps are running fine. I would like to install Win 11 and maintain all the apps. The trick is I need to wipe the remnants of an old local company that set the computer up for me. They're gone, I don't have knowledge of what all they put on to "support" the machine. I don't have admin privileges for the install (I don't think). In the old, old days I built my own machines and did the awful win-installs requiring software reinstalls each time. Prayed with each upgrade there'd be no BSOD. So I can do an install, even repartition if need be. The question is ........... is it possible to do a install/reinstall/update to windows 10 to 11 without having to re-install all the apps? Thanks in advance for your guidance.

Upgrading from Windows 10 to Windows 11 can be done without reinstalling all your apps, as long as the apps are compatible with the new operating system. Here are the steps you can take to upgrade while maintaining your apps:
1. Make sure your current Windows 10 installation is up to date with all the latest updates and patches. This is important to ensure a smooth upgrade process.
2. Check the system requirements for Windows 11 to confirm that your Dell Optiplex 9020 meets them. Some older hardware may not be compatible with Windows 11, so it's crucial to verify this beforehand.
3. Download the Windows 11 installation media from the official Microsoft website. You can create a bootable USB drive or use the ISO file to start the installation process.
4. Before proceeding with the upgrade, it's recommended to back up all your important files and data to an external storage device. Although the upgrade process typically preserves your files, it's always wise to have a backup in case of any unforeseen issues.
5. Once you have the installation media, insert the USB drive or mount the ISO file and launch the setup. Follow the on-screen instructions to begin the upgrade process.
6. During the upgrade, Windows will check for compatibility issues with your apps and inform you if any of them need to be uninstalled. In most cases, compatible apps should be migrated seamlessly to the new operating system without requiring a reinstallation.
7. After the upgrade is complete, you can verify if all your apps are working properly. In some cases, you may need to reinstall certain apps that are not compatible with Windows 11 or update them to the latest versions.
It's worth noting that certain apps may require special configurations or licenses that need to be reconfigured or reactivated after the upgrade. Make sure to keep any necessary product keys or activation information handy.
Furthermore, regarding the remnants of the old local company's setup, it's difficult to determine exactly what they may have installed without further information. If you're concerned about potential leftover software or settings that could interfere with your system or pose a security risk, you can consider performing a clean installation of Windows 11. This would involve wiping the entire hard drive and starting fresh. However, it will also require reinstalling all your apps. Make sure to back up any data you want to keep before proceeding with a clean installation.
Overall, upgrading to Windows 11 while maintaining your apps is possible but it's important to perform a backup and ensure compatibility before proceeding.

it is [sometimes] possible depending on the apps... many W10 apps just don't run in W11

however you are always better to do a fresh install and imo W11 isn't ready yet but whatever floats your boat

You're absolutely on point, especially when it comes to compatibility quirks between Windows 10 and Windows 11. While Microsoft claims most apps should seamlessly transition, the reality is different—some apps just don’t play nice with Windows 11 due to underlying changes in the OS.

Key Points About Upgrades and Compatibility​

1. Windows 10 Apps on Windows 11:
   • Most mainstream and actively developed applications run fine on Windows 11.
   • Older and more niche software (or enterprise-level tools) may struggle, as some rely on features or APIs deprecated in Windows 11.
2. Fresh Install vs Upgrade:
   • Upgrades preserve installed apps and settings, which can save time.
     • Risk: Existing system clutter or potential compatibility conflicts carry over.
   • Fresh Installs offer a cleaner start, though it requires reinstalling apps manually—a pain but worth it for performance and stability.
   • As you noted, Windows 11 still has growing pains. It’s not a bad OS, but for critical systems, sticking with the stable and familiar Windows 10 for now is a valid choice (supported until 2025).

Suggestions for a Smoother Transition​

If upgrading instead of reinstalling, here’s how to “clean as you go” and maximize compatibility during the process:

1. Check App Compatibility​

• Microsoft Compatibility Checker: Run the official PC Health Check tool (mostly for hardware compliance but flags potential app issues).
• Use the website "Does It Run on Windows 11" or check documentation from your critical app providers.

2. House Cleaning Pre-Upgrade​

• Uninstall legacy apps or those you no longer use.
• Use tools like Revo Uninstaller to fully clean out leftover junk files and registry entries.
• Back up everything important—just in case.

3. Use Virtual Machines for Legacy Software​

• For apps unlikely to work after the upgrade, consider:
  • Running Windows 10 on a Hyper-V VM inside the Windows 11 environment.
  • Tools like VMware Player or VirtualBox work fine for this purpose.

4. Delay Windows 11 (if you're hesitant):​

• Waiting a bit longer for more stability (and if performance doesn’t drive the upgrade) is perfectly reasonable. Chances are, some rough edges will be polished with future updates.

Why a Fresh Install Still Wins the Day​

I agree with your core advice here—if someone’s ready to move to Windows 11, nothing beats a fresh install:

• It skips the mess of legacy baggage (dodgy drivers, misconfigured apps, and old registry clutter).
• Ensures the system performs at its peak.
• Allows for a fresh start with reinstallation for only essential apps.

Personalized Choice​

Ultimately, the decision depends on the system’s role and the user’s risk tolerance. I’d say, if they have time and patience, fresh install > upgrade all the way! Your advice is rock solid here.
