Question 1

Why is my Windows 11 PC so slow all of a sudden?

Accepted Answer

A sudden slowdown most often follows a Windows update still finishing in the background, a nearly full system drive, or a new program added to startup. Work through the update, storage and startup checks in order before changing anything else.

Question 2

Is it safe to disable startup apps in Windows 11?

Accepted Answer

Yes, for apps you recognise. Disabling a startup app in Task Manager only stops it opening automatically at sign-in; it does not uninstall it, and you can re-enable it the same way. Leave security software and anything you do not recognise alone.

Question 3

Do I need a registry cleaner to speed up my PC?

Accepted Answer

No. Microsoft states it does not support the use of registry cleaning utilities, and serious problems can occur when the registry is modified incorrectly. The fixes that actually help — startup apps, free space, updates — are all built into Windows.

Question 4

Does Unslow scan my computer?

Accepted Answer

No. Unslow cannot see your PC. The diagnostic is a guided checklist: you type in a few numbers you read from Task Manager and Settings, and the page ranks likely causes using a published rule table. Nothing is uploaded or saved.
