PC slows down terribly

[sam707]

my pc?

No, this question was directed to the OP.

@sam707: You seem to be an experienced PC user, therefore these optimization tools may be helpful. My warning is for the unexperienced users: Don't use them.

true!

newbies should read the docs deep, before checking boxes randomly LOoOL

particulary with CCleaner (there is NO 'default' safe clean mode)

Personally I would be using  HeapTrace  to start with to make sure you are freeing
all your memory allocated.
 
  You may want to make sure the OneDrive is not active, Virus scanning does not keep
getting triggered. On Dells you have things like Bit locker running all the time. Swap file
maybe getting fragged and with Low memory to start with its hard for it to clean it up.

 If you are using API calls for Virtual Memory functions, beware that some of could hang
memory around for a bit before it releases it.
 
 Windows claims that user space memory allocation gets return to the OS after you app
exits however, I know for a fact that things like Handles of all sorts of objects in the OS do
not get free'd, at least not all of them..

 also make sure if you are executing processes from your code to not keep doing that before shutting them down... etc. you need to look at the task manager to see what is accumulating.

 I have Laz on a slow laptop with 4 G, it seems to work the same from start to end.

another awesome tool I share here

Real time =>
= cpu usage
= mem leaks / swappages faults
= gpu usage
= stack / heap track
= strings exe insider
= DLL versioning leaks
= online VirusTotal check for binaries
= ... and so much more
====
asm cycles statistics (helps select and refine optimizations for compilers)

free

sorry, windows only

It's a taskmanager power 1000

note : preferably run it with admin rights to view/manage all processes and threads

The main problem in general is that most people run too many programs in the background even if they don't need them right now...

People who don't know WINDOWS always have got too much stuff inside the RUN folders (REG, StartUp). To check this easily go and download "AutoRUNS". It's from MS and don't need to be installed, just run it and take a look how many things are running that nobody needs... (WINDOWS without AutoRUNS = big bullshit). Yes, I mean everything: drivers, services, programs, program parts. On a normal WINDOWS PC there is always way too much running that nobody ever needs.

For example NVIDIA drivers are poorly programmed when it comes to resource management. NVIDIA drivers install always a spying service that you can only kill if you delete the exe-file... Yes, even if you uncheck this inside the setup the service will be installed. And yes the driver is running fine without it... The same thing is going on with new PHOTOSHOP versions, but it's harder to get rid of those services... They should protect PHOTOSHOP but as everybody knows this will never work... it just costs resources... (big bullshit ... too..).

A standard WINDOWS computer runs automagically too much services that only a system admin with installed network really needs.... There is a lot you can delete or at least disable.

Cleaner-Software is a problem in general, there are some good tools but most of them are bullshit and can destroy a lot more than you think. And even the good tools are only for people who really know what they do and of course after creating a backup image (Acronis True Image, CloneZilla, Paragon Backup & Recovery, DriveImageXML...).

Another Tool from MS that might be helpful is "Process Monitor"...
Or take a look at "WhatChanged" or "jv16 PowerTools"... 

The worst thing ever: Antivirus-software... needs almost all resources that is available on a computer, at least with a standard installation. AV-software cannot work/protect you... but most people like to live in fear and believe what companies and politicians are telling them... (worst bullshit ever...). A good firewall can handle every malware without wasting time while scanning signatures... (only firewalls that can handle all processes...).

The easiest thing to check if a person has got a good/clean WINDOWS install: take a look at the TNA. If there are too much icons around then normally you directly know what's going on ...
