You should check with Qlik Support and the Release Notes in case there is a known issue with a Windows 2012 patch and QlikView.

I'm using QlikView 11.20 and QlikView 12.10 over Windows 2012 R2 and we conduct a full patch of all servers every other month. Apart from some serious performance issues in January and February due to Spectre and Meltdown, there has been nothing noticeable.

Those performance issues are now gone after subsequent patches.

If you want to reinstall the operating system (Windows 2012 to Windows 2012 R2) then make sure you backup C:\ProgramData\QlikTech or equivalent folder, but as with any operating system upgrade (not patching) you will have to keep a closer eye on your servers for the next days. There are no feature changes in the OS, but if you are using IIS there might be some extra settings.
