Slow Performance Fixer - PC Guide Hub

Before making changes: save your work and restart the PC once if it has been running for a long time. This tool provides troubleshooting guidance; it does not scan or change your computer automatically.

1 Identify the slowdown type

What best describes the issue?

Slow startup or long boot time Everything feels slow Apps take a long time to open Freezing, stuttering, or random pauses Only the internet feels slow

2 Check system resource usage

Open Task Manager with Ctrl + Shift + Esc. On the Processes tab, sort by CPU, Memory, Disk, or GPU to identify an app using unusually high resources.

What do you see while the PC is slow?

CPU is consistently around 90–100% Memory (RAM) is almost full Disk usage stays at 100% GPU usage is maxed out Usage looks normal or I am unsure

3 Free up storage safely

Low free space can slow Windows updates, virtual memory, and app performance. Use the built-in Disk Cleanup utility, then empty the Recycle Bin if you no longer need its files.

cleanmgr

Press Windows + R, enter the command above, select temporary files you are comfortable removing, and choose OK. Avoid manually deleting system folders or the Prefetch folder.

After freeing space and restarting, did it improve?

Yes, noticeable improvement Slight improvement No change I have not done this yet

4 Review startup and background apps

In Task Manager, open Startup apps. Disable only non-essential apps you recognize, especially those marked as having high startup impact. Do not disable security software or hardware drivers unless you are certain what they do.

What did you find?

Too many startup apps A heavy background process A process I do not recognize or trust Nothing unusual
