Is the Core i7-1355U fast enough for work?

Yes for office apps, browsing, spreadsheets and video calls. It is a low-power 10-core chip, so it trails H-series processors in sustained heavy work like video editing.

Can this laptop handle gaming?

Only lightly. It uses Intel integrated graphics, so older or simple games run at low settings, but modern titles will not.

Is 16 GB of RAM and a 512 GB SSD enough?

For most office and student use, yes. 16 GB handles many tabs and apps, and 512 GB is workable, though large photo or video libraries will need external storage.

Does it come with Windows 11 Pro?

Yes. Windows 11 Pro adds BitLocker, Remote Desktop and domain join, which matter for business use.

Is the screen good for photo or video work?

No. The 1080p panel is dim with limited color coverage, so it suits documents and web work rather than color-critical editing.

Can I upgrade the memory or storage?

Dell's 15-inch business models usually allow SSD replacement and sometimes RAM upgrades, but check the specific service manual before buying, since soldered configurations exist.
