It hinges on whether you're getting a newer version or not—likely it is, especially if it's been out for several months, as updates are typically released roughly every six months. Most PCs come with outdated software that can hinder the upgrade process significantly. Four hours still feels quite long, so check if your system uses only traditional hard drives or includes an SSD. If it has an SSD, a four-hour upgrade is definitely unexpected.
That means it takes longer than expected, though it's not uncommon for a regular hard drive—depends on how much pre-installed software was there before the upgrade. As long as the device remains responsive with lights or signals, I don't have major concerns right now. It's a bit disappointing you had to wait over four hours before using it. If problems arise later, restoring it to its original settings before updates can help speed things up, since fewer files need moving. Aggressive antivirus programs like Norton or MacAfee tend to slow things down the most.
