Stand alone app for windows problem

[DavJans]

I have written a stand alone app that we run on windows 7, 8.1 and 10. Three times now it stops working properly on windows 8.1 tablet PC's. The app shows up in the Task Manager under the Processes tab but that's as far as we get. I've tried everything I can think of to fix it, but ultimately the only thing that works is reinstalling windows (factory reset). Has anyone else seen this behavior? and is there a better way to get it working again?

I was able to fix this issue without reinstalling windows. In the task manager I was able to Analyze Wait Chain of my *.exe file. Here it had The name of the app and under that it had spooler (something to do with printers?) I ended the spooler under my app in the wait chain and it fired right up after that. This solution means nothing to me, other than it worked. but maybe it means something to the live code team. or someone else with the same issue. Thank you all for being awesome.
