Q&A...
Q. What does this mean for SDL Trados Studio users?
A. As Microsoft are withdrawing all support and assistance (as of 14th Jan, 2020), SDL will no longer be able to provide technical assistance for Windows 7 users. SDL recommend you upgrade your operating system to Windows 10.
Q.- I am operating Windows 7- Will my Studio licence continue to work after January 14th 2020?
A.YES- Your licence will not be affected and will continue to work as normal, as long as no other significant changes are made to your computer. SDL however, will no longer be able to offer official support. Should questions arise, please refer to the SDL Gateway and SDL Community resources.
Q.- I have a number of SDL App Store applications installed. Will these continue to work?
A. If you already have apps installed, these should not be affected. However, we will no longer provide technical support for applications installed on a Windows 7 machines. Please also note that new releases and/or updated apps will not be developed for Windows 7 machines!
Q. MS is no longer providing support/updates etc.! Is my computer still safe?
A. Providers of third party applications such as your AV (Antivirus), VM/Parallels, Office applications etc. will only normally update /bug fix/patch for supported OS versions. This means that your computer (W7) will not be on the latest stand and may become unstable and vulnerable.
Q- Can I upgrade my Windows7 for free?
A. The official response from Microsoft is that the free upgrades have now been discontinued and that you should purchase an upgrade.
Depending on your country of residence, it might be worthwhile using a search engine to see if you are still eligible to receive a free upgrade.
Q. I am using Windows 7 and an older version of Studio- When I upgrade the OS, should I also upgrade my SDL Trados Studio version?
A. SDL offer official technical support for those using SDL Trados Studio 2017 and SDL Trados Studio 2019 versions only. Should you be using an on older version of Studio (2009/2011/2014/2015), you may find that your legacy Studio version may not install correctly and /or becomes unstable on new Windows 10 operating systems. SDL recommend therefore that you update both the OS and Studio version!
