Many Windows users have confronted the reduced performance of their Windows computer, no matter which brand they are using or how high-end hardware they get. Your computer can slow down for a whole host of reasons, and what’s more, it may not be immediately apparent which element is decreasing your computer performance. The fastest way to fix your computer and get it back up to speed is to run through the list of the most common problems below and follow the guide after to fix it.


Why is my computer so slow? How to fix it?


Too many programs and services run on the start up

Nearly all the programs would understate or reconfigure silently the allowance of their auto-start when you boot up the computer, which takes a lot of time to start, especially the antivirus software.

How to fix slow boot time:

Reduce Startup Items

->Press Ctrl+Alt+delete on the keyboard to open and choose Task Manager.

->Choose the ‘Startup’ tab of the Task Manager Window, and right-click any programs that don’t need to be opened at startup and select ‘Disable’.

Delay Services

The same theory as the auto-start programs. You can delay some start-up services because they are not needed the minute you start up your PC.

->Open the Start menu, type services, and press enter—then right-click on any service to change its Properties.


Memory-hungry hardware

Temporary files, system junk files and duplicated files accumulate on your computer and clog down the hardware once you start it. Removing these files can potentially free up GBs of space on the hardware. Also, defragging the hardware organizes the files and folders, helping to free up more space.

How to fix stuffed and fragmented hardware:

->Press the Windows key + Q, and type Disk Cleanup in the search box, and then choose to Free up disk space by deleting unnecessary files.

->The scan time depends on the number of your files. After that, select the file type you want to delete.


You got a virus or malware 

If you do not use Windows Defender or any other antivirus software, then it has a big chance that your slow computer gets a virus or malware.

How to fix an infected computer:

->Make sure your antivirus program is up-to-date and then run a full system scan, which should detect and remove any malicious code.

->The better solution is to avoid that: don’t visit suspicious websites or open the emails from anonymous or strange senders; don’t download the files from untrusted websites; run antivirus tool.
