I was booting off an ssd originally and have a regular hdd as backup. then i had to get my laptop repaired. i removed the ssd and shipped the laptop off. upon receiving it, i popped my hard drive back in and changed the boot settings in bios to my ssd instead of the hdd. it boots just fine, but my wallpaper was gone and i cant access certain things like my computer, control panel, etc. an error pops up saying that it wont initialize. etc.
is there a procedure i must do? i tried sfc scannow and it restored my desktop, but it said somethings were unable to be repaired. im also wondering how come it didnt just work right away as if i never sent it in for repairs. i stumbled upon a guide that said how to re register my dlls... is this a good idea?
