Technical issues. Hardware, software upgrades, misleading technical information, etc. For example, A USB smartcard reader stops working. After some trial and error, I get it working in another USB port. Was it an issue with the original port, with other connected USB devices, say, an external disk drive, affecting it, a problem with the reader itself, some recent updates, e.g., to device drivers?
As I write, my primary PC is making a second attempt at the latest Windows 10 feature update. It had successfully completed on my newer PC, although it seemed to take forever. I knew something had happened when I took a short nap and woke up to find my PC ready for logon and it did not launch into some sort of "preparing your desktop" step. I quickly confirmed the update had failed by looking at the Update history. No clue as to what happened, but at least the system had reverted to a usable state. [It has since failed again while I composed this post, at about the 58% completion point. I tried running the Updates troubleshooter to no result. This is not the first time I've run into multiple Update failures.] My older devices are "not yet ready" for the update. I know in the past they eventually get usable updates, but I find it annoying to having different versions across my devices. But even launching Setup/Windows Update can be an issue at times.
Then there's Adobe Flash Player. There are a number of issues here, including its use with certain mandating training software I use. A big upcoming issue is the product's end of life at the end of the year, with all major browsers announcing related end of support. There have been some chronic security lag patching, never mind browsers handle Flash Player support differently, e.g., Chrome vs. Firefox. One of the things I found that using the software through Chrome required manually changing the browser window to enable Flash Player; apparently there's no way to whitelist URLs to allow Flash Player. I discovered the Player issue when I got to a simulation exercise in the courseware and it just wouldn't advance--it was just spinning. I had contacted technical support; he didn't seem to run into the issue using my account--and then at some point he mentioned using Firefox. I recall in the past when using cable TV scheduling with Chrome. I would get some "right-click to enable Adobe" thing but at some point it changed to clicking at the start of the address prompt. However, in the case of the training software, I never got a warning to the effect there was a Flash Player issue.
And then I got to this one course where Flash Player was allowed, but I got a warning the courseware required Flash Player to display the screen. Now what? I remember the support guy had initially tested on Firefox. So I launched my copy of Firefox, only to discover Flash Player wasn't installed, and I eventually realized I had to download the player from Adobe. I remember wondering how to verify the software was installed in Firefox. I eventually launched the courseware and saw something to the effect of right-click to use Flash Player.
I know when I wrote my recent posts on issues with government smartcard CAC's I saw an emphasis in other sources on running the 32-bit version of Internet Explorer in order to use ActiveX functionality in order to use PKI for secure email (digital signature and encryption). If you're running a 64-bit OS, like many of my own PC's have, you should have both 64- and 32-bit versions. Long story short, I started launching the 32-bit iexplore. For other reasons, I started looking at Process Explorer from Sysinternals to look at the iexplore process(es) (right-click/Properties to see the executable path name). That's when I discovered 64-bit IE was still being launched concurrently; more to the point, even if I launched 64-bit IE, I could still use secure email functionality; I think I read somewhere that IE-64 will open a frame to support 32-bit requirements when needed.
On a side note, I have discovered that using a VPN can have some unpleasant side effects. For example, I found sending an email using Gmail was failing but if I momentarily disconnected the VPN, I could connect to the SMTP server. I've also found at least a dozen secure websites balking they don't recognize my IP. From a security standpoint, I appreciate the checks, but it is a usability tradeoff and somewhat defeats the purpose of using a VPN.
