Quick suggestion - I found a better way to remove all crapware (dealing with an HP machine just now). I found that even if you uninstall the bloat, the crapware can come back with an update or show up on every user you set up with the computer. Boot up the new machine and go ahead register the computer, update the computer firmware, etc. Once you are done use the windows media creation tool to create a USB windows 10 or 11 install (I did win 11). Reboot the computer to the USB. Once you get to the install and have to choose your drive, go through and delete all existing partitions and then on a clean drive, install windows. No more bloatware (other that what windows gives you) and you got your self a pristine machine to do some of your other helpful edits.Microsoft's operating system has some default settings that slow you down. Stop what you're doing and tweak these .

While keeping system files hidden may be fine for a novice, I don't agree about keeping extensions hidden. I've always thought that was the worst idea MS ever had when they began hiding extensions by default way back in Windows 95. In fact, it's a known security risk that has been exploited by spammers with email attachments going back to '95.It's NEVER a good idea for novice users to unhide system files and extensions (and your comment about not knowing if it's a XLS or XLSX is fluff, as Office handles both just fine, and there may be a specific reason it needs to be in the older format), nor delete the system restore partition.
