You might also want to install Internet Explorer 11 on the old system before you run the in-place upgrade to test the compatibility of existing web applications because Windows 10 doesn’t support older versions of this browser.Windows 10's power settings allow you to tweak various aspects of the operating system that involve power usage. Typically, if you don’t want to continue using a large number of applications, an in-place upgrade does not make much sense. In addition to these restrictions, other reasons exist to consider a fresh install. If you encrypted drives with a third-party solution and the vendor does not explicitly support in-place upgrades (BitLocker supports in-place upgrades).If you are working with a dual- or multi-boot system, if your Windows installation uses native VHD boot, or if you are running Windows To Go. ![]() ![]() If you intend to change to a lower Windows edition: In-place upgrades only allow you to migrate to the same or a higher edition, for example Windows 7 Pro to Windows 10 Pro or Enterprise.If you want to change the language version: For instance, an in-place upgrade from a German to the English operating system version is not possible.Reasons for working with UEFI could be the usage of Secure Boot or Device Guard. If an older Windows has been installed in the BIOS compatibility mode on a UEFI PC and you now want to use the UEFI firmware natively, you have to modify the disk layout (among other things, you have to use GPT instead of MBR).If Windows XP or Vista still runs on the PCs.If you move from a 32-bit installation to a 64-bit version (or the other way around) because of problems with drivers and applications.Thus, a fresh install is required in the following cases: The most important reason for a fresh install (wipe-and-load) This is particularly true if you use the upgrade as an opportunity to perform major modifications. Scenarios for a new installationĮven the significantly improved in-place upgrade, which Microsoft recommends for most migrations, is not suitable for every upgrade. Rather, you have to deploy the original install.wim from the installation media with MDT or SCCM. By the way, such modified system images cannot be used for in-place upgrades. Of course, such a rollback is difficult to accomplish after a fresh install because the existing Windows installation is removed and a new (adapted) system image is copied onto the computer. You can also downgrade to the previous Windows installation manually if, for some reason, the new Windows isn’t up to scratch. This may also happen automatically, for instance, if the first Windows 10 boot up fails. Downgrade to the previous Windows installation possibleĪnother advantage of an in-place upgrade is that you can roll back to the previous Windows installation at any time. Microsoft provided a detailed description of the in-place upgrade process on the recent Ignite conference during the “Upgrade to Windows 10: In Depth” session, which you can view on Channel 9. These settings are automatically applied during the setup process. The database also contains information about the configuration that is required to make the application run properly under Windows 10. Setup uses a huge database to verify the compatibility of each application with Windows 10. Īlso in the case of an application migration, setup does more than just copying registry entries. The compatibility of existing programs is determined and established with the help of a database. Admins can also specify a folder with additional drivers. At this stage, setup downloads the newest drivers from Windows Update. If the preconditions for an upgrade are met, the system will boot up WinRE and copy the Windows 10 system files to the corresponding drive. The new upgrade process is complex and begins with an extensive evaluation and inventory of the computer. Device driver update, application compatibility check ![]()
