Why do browser tabs keep refreshing?

Windows is likely under memory pressure. Close unused apps, reduce extensions, and increase virtual memory if needed.

Do I need a registry cleaner?

No. Focus on startup trimming and storage cleanup - registry cleaners offer little benefit and can be risky.

Why does Outlook slow down over time?

Large PST or OST files and indexing backlog cause delays. Compact or archive old mail and rebuild the index.

Will disabling services break Windows?

Do not disable core services. Only limit unneeded startup apps and schedule heavy tasks for off hours.

What about BIOS updates?

BIOS updates can improve stability and performance. Apply vendor updates carefully and back up first.

Can PC-Care.ai maintain performance automatically?

Yes - it schedules cleanup, trims startups, and alerts you when drivers or storage need attention.

Choppy scrolling hints at graphics or CPU contention. Outlook delays often track search indexing backlog or large data files. Tab reloads point to low available memory. Loud fans suggest sustained CPU load from background processes.

Manual fixes - step by step

Clean temp files and Windows update leftovers
Limit OneDrive and backup sync during work hours
Disable high impact startup apps
Update GPU and storage drivers
Check for malware with Microsoft Defender
Adjust visual effects for performance

Cleaning temp and update caches restores disk headroom. Scheduling sync tools reduces contention. Disabling high impact startups lowers idle CPU. Updated drivers fix stability issues. A malware scan ensures no hidden miners or adware. Lighter visuals reclaim resources on older hardware.

Prevention - keep the issue from coming back
