Saving animation from program
For the intellectual challenge, I've written a justBasic graphics string-rewriting program which displays the first few iterations of the Hilbert space-filling curve, each being traced out in turn. The whole sequence takes about ten seconds. Akin to Print Screen for saving a single image for future use, is there an easy way to create a video file of my animation? I'm running Windows 10.> 2A00:23C6:AA0D:F501:216F:9DF0:B2D0:30DB (talk) 12:55, 22 March 2023 (UTC)
 * Perhaps a screen recorder would be in order? --Ouro (blah blah) 16:06, 22 March 2023 (UTC)


 * If you record a sequence of snapshot images as a sequence of gif files (say one every 25th second), which I guess can be automated using a script, the gifs can be combined in the form of an animated gif. There is software, both in the form of apps and as online services, to convert animated gifs to MP4 videos. --Lambiam 20:35, 22 March 2023 (UTC)


 * Thanks. The intellectual challenge of implementing the suggestion by Lambiam is too great for me, but I managed to get something acceptable using a free screen recorder called Free Cam, which produces .wmv files.>2A00:23C6:AA0D:F501:98B3:8F15:9F9D:BFC (talk) 16:42, 23 March 2023 (UTC)
 * Then it's a learning experience, and we wish you good luck! --Ouro (blah blah) 02:14, 27 March 2023 (UTC)
 * In JustBasic you can look for a folder called SPRITES. This contains images saved as BMP files. The BMP file format is simpler that GIF (because it doesn't involve indexed colors or data compression, you can inspect each individual pixel using a Hex editor) and you can look for any video editor able to make a slideshow from BMP images. The JustBasic commands "loadbmp" and "unloadbmp" let you construct your animation as a sequence of sprites, see this tutorial https://www.youtube.com/watch?v=fuQk2q13iVc (Pt. 1 & 2).

Windows 10, version 21H2
Somehow, no matter how many times I've tried, I can't get this update into my PC. It downloads and then it tells me it is ready to install but I need to restart my PC. After I do that, the update starts, goes up to a certain percentage and then stops and the screen starts reading "Undoing changes" after which the PC restarts and informs me that the update couldn't be installed only to tell me that I need to get that update soon after which makes the whole cycle restart. Can someone help me understand what exactly is going on?

I've read only that storage could be a problem. Somewhere it said that I needed almost 30gb free in drive C for that to work. I have 21gb free but I literally can't get more space as I've removed almost everything. The whole drive is 60gb and that ~40gb is occupied by the OS and the default programs. Is that really a problem? Can I do anything about it? Am I stuck forever in this loop?

For reference, I currently have version 1909. - Klein Muçi (talk) 18:11, 22 March 2023 (UTC)
 * This seems worth a look. I don't use Windows, so I can't try it out personally. --Ouro (blah blah) 03:59, 23 March 2023 (UTC)
 * Ouro, thank you for trying to help! I just tried it but the troubleshooter says it didn't find any problems. :/ — Klein Muçi (talk) 11:56, 24 March 2023 (UTC)
 * I know there's a tool that will help your computer update (Windows Update Assistant maybe). I would try that. ― Blaze WolfTalkBlaze Wolf#6545 12:15, 24 March 2023 (UTC)
 * Blaze Wolf, I have tried it many times but still the same loop goes on. I've also tried manually resetting the Windows Update components (what I believe the aforementioned troubleshooter was trying to do automatically). I'm starting to believe it is the storage problem but I have no idea how to solve that. :/ — Klein Muçi (talk) 12:28, 24 March 2023 (UTC)
 * Is there any way you could add extra storage to your system, e. g. second drive? Bear in mind, 60 g is a small drive by current standards. My entire Linux installation, for instance, is 17 g, come to think of it, I thought it would be less... --Ouro (blah blah) 02:14, 27 March 2023 (UTC)
 * Ouro, I did a risky experiment and transported some system (?) files to my other hard drives (which are rather big, 500+gb each). This caused some programs to lose their current configurations and behave weirdly but that gave me 35 gb free storage on drive C so I tried redoing the update. Much to my dismay, it again went up to around 25% and then the PC restarted and the text "undoing changes" came up on screen. Thankfully for my configurations, everything went back to normal after I returned those files to their original place but the version still didn't change. When I check about it, it still says version 1909. I even tried forcing the update with that assistant program while I had +30gb free storage but unfortunately the same thing happened. The computer I'm using is a used one from a gaming center. Maybe the prior owners have tampered with the OS license somehow and that is blocking the update from happening? Because now we know that storage is not a problem I believe. — Klein Muçi (talk) 05:52, 27 March 2023 (UTC)
 * Or may be an incompatible driver is blocking the installation. Ruslik_ Zero 20:37, 28 March 2023 (UTC)
 * Ruslik0, maybe... I'm not sure how would I find out or fix that... — Klein Muçi (talk) 11:28, 29 March 2023 (UTC)
 * I advise you to try a clean installation of the latest version of Windows 10. Ruslik_ Zero 12:21, 29 March 2023 (UTC)
 * Ruslik0, a.k.a format? Or are we talking about something else? — Klein Muçi (talk) 12:24, 29 March 2023 (UTC)
 * It can be with formatting but not necessary so. Ruslik_ Zero 12:37, 29 March 2023 (UTC)
 * Ruslik0, well, if someone can help guide me there, I could give it a try as long as I don't lose my files. :P — Klein Muçi (talk) 14:31, 29 March 2023 (UTC)
 * The official guide is here. You can run the setup from within the existing system. Then you can choose what to keep. I also advise you to backup all your files to another (external) drive before running setup. Ruslik_ Zero 19:33, 29 March 2023 (UTC)
