the version of windows that microsoft install on their tablets is slightly modified.

Also make sure it's not running is 'S' mode.
Stands for STUPID and is what most newish machines are now coming with.

If it is in stupid mode it won't install ANYTHING that isn't in the microsoft app store - ie: most of what most people use.

Google - remove windows 10 s mode.
basically you go into security and update settings and go to the store and it'll let you change it to normal (useable) winodws mode.

If it's not that, then no idea.
