If you are installing Windows 10 on a PC running Windows XP or Windows Vista, or if you need to create installation media to install Windows 10 on a different PC, see Using the tool to create installation media (USB flash drive, DVD, or ISO file) to install Windows 10 on a different PC section below. You need to reinstall Windows 10 on a PC you’ve already successfully activated Windows 10.You have a license to install Windows 10 and are upgrading this PC from Windows 7 or Windows 8.1.PatchCleaner is available for Windows Vista and later. It "only" freed up 312MB on our test Windows 10 laptop, but that’s still worth having, and not something we could easily achieve with standard cleanup tools. We’ve seen reports of people recovering gigabytes of drive space using PatchCleaner. That’s definitely our preferred option, as if you notice problems with an application, you can easily copy the files back. The developer reports that "there is an issue with the way Adobe Reader patches and updates, where PatchCleaner will remove required patch files." He’s addressed this by building a filter system which enables ignoring Adobe or any other applications you like, but it does illustrate that the program can make mistakes.įortunately, once the scan is complete PatchCleaner offers to move files, rather than delete them. The program then scans your \Windows\Installer folder, identifies installers and patches which don’t appear on the WMI "installed" list, and identifies these as "orphaned." Launch PatchCleaner and it first uses WMI to obtain the official list of Windows Installer-based programs and patches.
