I have been having a rather 'strange' problem with 64bit over the past couple of weeks. It started with 3.6 and continues with 3.7.

I keep shortcuts of my frequently used programs pinned in the task bar (a'la quick launch in XP), when I start them I expect the pinned icon to highlight.

For some explicable reason over the past couple of weeks when I start the calibre 64 bit edition from the taskbar it doesn't always combine the running instance icon with the pinned icon. It will for a while (as in hours) but then it starts creating a separate icon for the running instance.

If I run a Repair on the calibre 64 bit msi from Control Panel->All Control Panel Items->Programs and Features it fixes the problem - for a while, like a few hours or perhaps until next day. I have no idea what triggers the sudden misbehaviour.

Another symptom is this, if I do a restart of calibre 64bit with Ctrl+R, a separate icon is always created. If I then close calibre, and if I'm lucky, when I start from the taskbar icon a separate icon is not created for the running instance, I get a combined icon

I've been using 32bit calibre since Friday morning (i.e. 3 days). None of the above has happened with that edition of calibre. But since Friday, the 64 bit edition has misbehaved in the manner described, even though I've hardly used it

Nor does it happen with other 64 bit programs that use the 'Common Application Id' mechanism (or whatever it's called) that calibre uses. I'm referring to the one that requires a running instance of the program to be pinned from within the task bar itself, rather than using the 'Pin to Taskbar' option from the Start Menu.

I don't know if or how this relates to other 64 bit problems that have been reported of late - it's certainly not the same symptoms, hence the new post, but... one has to wonder.

If anyone knows what the Control Panel->All Control Panel Items->Programs and Features->Repair does that could give me a clue. Whilst its irritating, it's not enough to make me want to do a non-destructive reinstall of Windows.

One thing I haven't tried is to run an old version of calibre - such as 2.85.1. Might try that tomorrow. I'm not running the server, software is installed in 'default' locations, libraries are on a separate internal hard drive in a directory dedicated to all e-bookish data.

@JSWolf - FYI when it happens, it happens in Safe Mode too. And I have run sfc /scannow and my Windows 10 Pro is up to date as of last Wednesday's patches.

Added : I have tried disabling all start up programs, shell extensions, scheduled tasks, and non-critical services such as Indexing, and Backup - the Ctrl+R restart misbehaviour still happens, so I assume the 'random' one will too if I wait long enough.
