#Windows11 wat
I'm restoring files from a customer's PC-in-pieces to a new PC, extracting 15 GB of files from a 7z archive on the same SSD as the destination directory.
The built-in File Explorer treats the 7z archive like it does ZIP archives: fancier directories. But using File Explorer to extract gave a duration estimate of "More than 1 day", spun up the fan to top speed, & genuinely took longer than a whole day do reach 1%.
I installed 7-Zip, used it instead, & was done in mere minutes.

The PC in pieces was a laptop with broken hinges & a touch screen surface so thoroughly cracked that it sensed 10-20 fingers touching & swiping the screen in different spots constantly, rendering it unusable without teardowns more expensive than just yanking the HDD & borrowing a USB enclosure to do an "archive everything now, extract the required bits later" recovery.
