Looks like it's a programming interface that allows access to virtual file systems without needing to know much about kernel drivers. Basically a go-between for programs and the OS filesystem.
I would not sweat its removal unless you're doing programming or doing a lot with Virtual Machines, and even then the VM will reinstall it (or warn you) when you go to work with it I suspect. Intellectually speaking, it seems like that interface could be maliciously used to trick the OS into writing files, but I honestly don't have enough OS programming experience to say for certain. So, you may have dodged a bullet if malware was using it.
I generally agree with Threadweaver... generally speaking, if something legitimate actually needed it and you were missing it, it should pop up a notice stating you need it, and either ask you to download/install it, or ask you if it can get it and download/install it.
Generally, I like installing everything a system needs and only what it needs at time of reset, but sometimes you just cannot know, but in any case if needed at all, should not be a big deal.
In Acronis the clone tool should be under tools, not in the backup part. Not sure if the free version would have it or not. Seagate and WD both have free versions of it but they only work if you have one of their branded drives installed. Seagate's is called Discwizard.
Macrium Reflect also can do the job. I've used both at work before. Acronis handles bad sectors better generally but Macrium can sometimes handle other issues better.
I looked Clonezilla, but I couldn't make head or tail out of it. In the end, I opted for a newer refurbed PC from Amazon. Nothing fancy, but enough to tide me over for another few years.
In the spirit of passing on advice nd information for those who might need it, my dad's laptop had a problem in that it kept switching itself off after about 45 minutes, which meant it couldn't be properly updated. It wasn't a battery issue, and I don't think it got too hot.
What I did to resolve it was to reset the rollback the install on the PC with the wipe all the programs function and updated Windows.
Is anybody who uses Outlook noticing a change in the layout? I've been stuck using my Fire 10 tablet only the last few months, and happen to like the way Outlook was laid out on my device. Then this morning, I opened my email to discover it hd changed to the standard Windows look, with Focused/Other seperation of emails. Funny thing is, this only applies to *my* email - my father's is still on the former 'tablet' format, with the inbox on side.
Actually, I meant how it looked on Android. My bad. My laptop had some isdues back in March and had to be repaired, and right after that the 'stayvin place' order for CA came down. My laptop is still wirh my local repair guy, but I expect to get it back within the next few days.
