Xaver Have been running PTE, now 7.5.7, on Windows 8 for several months on new Dell PC (16GB of RAM, Intel I7 quad core, AMD Radeon 7870 video card with 2GB video RAM) with no problems. Despite the well reported problems with 8, including the email client, lack of start button etc., I find it stable and quick. The security issue over running exe files is easily circumnavigated and there are no problems when installing updates to PTE and installing PTE does produce an icon on the desktop unlike some software. The software I run alongside PTE for making sequences, Adobe Audition 3, Adobe Premier Elements 10 (for video clips) and Photoshop CS6 also run with no major issues in Windows 8. Problems with video drivers in 8 (possibly also down to AMD) means that CS6 cannot be run using the advanced option in the use of the Performance - Graphics Processor options in CS6 but I cannot see any difference as filters etc. work instantly and have had only one crash with CS6 in four months. I also have Topaz filters loaded and they work as well as in 7. All in all, happy with most aspects of 8 apart from the inadequate email client and unnecessary preinstalled apps. Regards Adrian
