Since you have the cookies to keep configured in CCleaner how about checking your web browser settings. In your web browser make sure it's not configured to clean when you close it since that's another way things you'd prefer to keep could inadvertently get removed.

Probably a long shot however something else to check is make sure Internet Explorer isn't set to Work Offline mode - even though Win10 doesn't necessarily use it. Although with Win10 I haven't the foggiest clue if that will cause a failed installation like it definitely would back in the WinXP days when an installer needed to phone home or even download data from the web.

Change log is always on this forum in Annoucements area: https://community.ccleaner.com/forum/5-announcements/

Wish that still existed officially instead of being only available on download sites that remain to archive it, luckily it still works on Win10 for now which I'm surprised hasn't broken compatibility with it yet.

Especially with modern versions of Windows (no so much on old versions like WinXP). For instance modern versions of Windows like Win10 will write to an drive even if it were on an external drive of any type (USB Flash Drive, SD Memory Card, Portable Hard Drive or SSD) modern versions of Windows create a System Volume Information folder that consumes a few small bytes. Now imagine if that overwrites a very small portion of a file you wish to restore.

I had the same issue yesterday with 720p and 1080p, and I'm not using CCleaner Browser, although it resolved itself in a few minutes. Could be that YouTube is being over-used at the time, then again some ISP's throttle YouTube. One creator on YouTube stated his ISP throttles him on there at 5mbps.

No.

1) It has no ability save scans. Once you exit the program it's gone, starting the program again means starting over from the beginning.

This seems like setup spam therefore this topic is closed. Also that's generic general information you can Google or look up on YouTube.

I don't think many of them remove their browser add-on/extension, at least not the antivirus software I've used over the years. In some the browser add-on/extension uses it's own unique installer/uninstaller as seen in Windows Add/Remove Programs.

If that's in your web browser(s) it might be an add-on/plugin you can uninstall using the web browser(s). Or they may have put it into the registry somewhere. Personally I'd ask on their forum to see if they know exactly where it's located, and how to remove it.

If you have an external/portable drive, or even another internally installed drive that has the capacity to restore the videos try restoring onto it. Do not try to restore onto the exact same drive where the files were deleted, since that has a significantly higher chance of overwriting what you wish to restore. I don't think your work will stop there though, you're likely in for a chore and you may or will have videos that won't play after being restored, and you may need to use a tool like the free Avidemux to re-save/re-mux them (or some other video tool) to see if they'll play in your media player. Restoring is always a long shot which is the reason it's critical to always have backup copies, preferably three known good backup copies (since any disk drive will eventually fail) of everything important to you which may seem like paranoid overkill but with accidental mishaps and malware it can be a life-saver.

There is always a risk, and especially so if the hard disk has been in use since the accidental delete happened.

Might be a combination of using the registry cleaner and some weirdness that is in Win10 from time to time, and they did just have the updates Tuesday - perhaps just a coincidence. Restarting a computer is always the first thing to try, sometimes a session can just be buggy and Windows (any version) can be very finicky and weird sometimes. With Win10 in particular I've seen it have odd or buggy behavior with external USB drives as if they were never initialized or formatted (how a brand new SSD arrives) like there was nothing on them and rebooting and using the drive in the same USB port won't fix it, however what will fix it is to unplug the drive and plug it into a different USB port and Win10 all of a sudden correctly sees the drive.

If you hibernate/sleep your system it won't save the Recuva scan results and you'll have to start over from scratch.

You could go this route: 1. Download and install either Revo Uninstaller Free, or Geek Uninstaller Free. 2. Download the official Norton Remove tool. 3. Uninstall the Norton product with one of the free uninstaller programs mentioned in step 1. Either one will do and both more-or-less do the exact same thing by removing extra leftovers that the standard uninstaller ignores and leaves behind. 4. Reboot the system even if not asked to do so. 5. Run the official Norton Remove tool. 6. Optional: Manually hunt through the system looking for additional Norton leftovers in Program Files, ProgramData, and AppData folders. 7. Reboot the system again, and you're done.

When defragmenting modern hard drives try to find out by looking at their documentation/specifications usually in PDF documents on the manufacturer websites such as Seagate, Toshiba, Western Digital what exactly is the drive technology, i.e.; CMR, PMR, or SMR. Also see (if relevant to your situation): https://en.wikipedia.org/wiki/Shingled_magnetic_recording If you're trying to maintain any drive that uses SMR (which were sold unlabeled to consumers) they can have a serious performance penalty since they'll perform their own internal maintenance that the end-user has no control over, and trying to defragment such a drive could take a very long time.

A profitable mistake.

You can have CCleaner automatically clean those files by inputting an Include: https://www.ccleaner.com/docs/ccleaner/using-ccleaner/including-files-and-folders-for-cleaning Edit: Note that this will only work if you're using Custom Clean, located in: Options > Settings

It doesn't clean inside the Program Files or ProgramData folder. It only removes the unpacked setup files after running setup.exe which will get unpacked into: C:\NVIDIA

I don't know anything about Mac OS having never used it. Perhaps try to get malware removal help on a Mac forum, or go directly to Apple to find help resources.

Win10 has issues with external/portable SSDs, safely remove them and plug them in a few minutes later and it doesn't remember having just optimized the SSD with Trim minutes earlier. They should fix or implement remembering that, and preferably keep the last date and time for the device/hardware ID optimization in the registry - or since they're so damned insistent on creating locked System Volume Information on every disk type they could store it in that locked folder.

One workaround for older OSes (I'm not sure if it's Win8.1 specifically, although it has been recommended for Win7) is to instead download and install the Slim builds going forward (something to do with how the installer works now): https://www.ccleaner.com/ccleaner/builds Also check your antivirus logs, not too long ago a couple of antivirus' wouldn't allow a new version due to false positives.

You could try re-saving the file with Avidemux (open source/GPL) without re-encoding/transcoding it to losslessly restore it -- but you're going to have to know the specifics of how the file was saved originally, i.e.; video codec, and audio codec, and what the file extension is. Doing that would write a header in the video so that playback software and hardware would know what it is and how to play it but that's of course assuming the video file is actually recoverable and intact, it might not be. Here's the link to Avidemux Portable, it doesn't install anything so if it doesn't work you can delete it without it leaving anything behind on your PC.
