Yes. Each 'restore point' associates with a specific backup copy of the registry hive files. If your pc is not startable from the device containing the befouled registry -- not even in 'Safe mode with Command Prompt', then you can boot from a different device, e.g. a flash drive, and then do...

I've used Revo Uninstaller (there's a free portable version available) with good results -- I note that it always creates a restore point before it does 'anything else that could matter'.

@TVG320, rosettacode.org has 'tasks' with program code solutions in multiple languages. In many of the tasks, you can see the same (or a very similar) algorithm being implemented in different languages. Here's a sample link to a category page there...

If a registry-edit-engendered error is preventing Windows from starting normally, then booting into 'Safe Mode' should be tried. On most PCs, hitting F8 repeatedly about once per second during bootup will get you to a startup menu that includes Safe Mode as an option, but the exact procedure can...

You didn't say for what purpose you might need to edit the registry (there might be another way). Regarding backing up the registry before editing: rather than trying to manually backup the registry hive files, the simplest and safest way to way to do an effective backup, so that you have the...

The hybrid solution consists of two battery cells connected to each other in parallel, connected in series to a third cell. Assuming 1.5v cells, the voltage for that arrangement would be 3v, and the current available would be that of the third cell. I would say can't and shouldn't try -- the...

Presumably you meant three in parallel. Batteries connected in series produce a voltage equal to the sum of their individual voltages, but the current is not summed, because the series connection does not provide a per-component increase in electrical throughput path capacity, as parallel...

At the park a day or 2 after the vernal equinox, this little fellow stopped by for a snack.

If you have a access to a JUC400 wormhole switch USB device, you can plug it in, then let it run its uninstall to remove its files when you exit. The leftover files are harmless, but aversion to leaving such remnants around is understandable. As others have suggested, you might want to clone the...

The J5create JUC400 Wormhole USB transfer switch is a device that allows drag & drop file transfer, keyboard and mouse sharing, and clipboard sharing. When you plug it in, it starts a virtual CD drive, from which it installs a temp program called wormhole.exe (and supporting files -- you can see...

There are a lot of things that can seem counter-intuitive, depending on the quality of your intuition. Intuition can be re-trained. ##-## @Dullard Reference: https://www.physicsforums.com/threads/archimedes-principle-a-rock-and-water-magic-trick.1051427/

I'll take a stern reprobation for this one if I have to (I request mercy); it was too good to pass up: One will not need to understand the language. The formulas speak for themselves. -- @fresh_42 Reference...
