Since a recent Windows 11 update, my HP all-in-one computer has become noticeably slow. The cursor sometimes lags or freezes, and programs such as Word take longer to respond, although I do not see any error messages. I mainly use the computer for social media, Sudoku, writing books and poetry in Word, and storing files through OneDrive. The computer has an AMD Ryzen 3 3250U processor, 8 GB of RAM, integrated Radeon Vega 3 graphics, and about 134 GB used out of a 238 GB drive. It is running Windows version 26200.9550.
I have Storage Sense enabled and run Iolo System Mechanic nearly every day. It repeatedly reports registry problems, junk files, and low memory. Cleaning these items sometimes improves performance briefly, but the same warnings return later, even when the computer has been idle. I have already disabled most startup apps, installed available optional Windows updates, and reduced some visual effects. I have not removed unfamiliar applications because I am worried about uninstalling something important.
I am not very comfortable with advanced troubleshooting and want to avoid losing my documents or access to the computer. Could the hardware be too limited for Windows 11, or might the problem be related to the drive, memory, or a background program? What safe checks should I try first?

Your computer is on the lower end for Windows 11: 8 GB of RAM and integrated graphics can be limiting, especially if several programs or OneDrive are active. The processor cannot realistically be replaced in an all-in-one system. You may be able to improve things by upgrading the RAM, but first check whether the model supports it and have a repair shop do the upgrade if you are unsure. It would also be sensible to start planning for a newer computer, while keeping this one for now if it remains usable. Make sure your important Word files are backed up before making changes.
I would not rely on registry cleaning as the main solution. Those utilities can repeatedly report items that are harmless, and cleaning them usually does not fix an underlying performance problem. Before changing anything significant, confirm that your documents are backed up in OneDrive and, ideally, on another drive. Then check Task Manager while the computer is slow to see whether Memory, Disk, or CPU usage is staying near 100 percent; that information can point to the real cause.
One useful thing to find out is whether Windows is installed on an SSD or an older mechanical hard drive. An SSD is much faster and can make a major difference to startup and general responsiveness. Open Task Manager with Ctrl+Shift+Esc, select the Performance tab, and click Disk. It may identify the drive as an SSD or HDD. If that is confusing, a computer shop can check it safely.
The Ryzen 3 3250U is listed as compatible with the basic Windows 11 requirements, but meeting the minimum does not guarantee a smooth experience. A clean Windows installation might help if the system has accumulated software problems, but it is not a good first step for someone worried about losing files. A trusted technician could check the drive health, available RAM, startup programs, and Windows installation before recommending anything more drastic.
