Windows 7 performance degrades over time

I'll have to test that on Monday. I'm near the end of the day and usually this time does see significant lag - I haven't used my computer nearly as much today as I have in the past. Then there is little chance to rectify the situation Maybe somehow simplify the model, for example to convert Schedule table to AutoCAD table, etc..

There are many things that can contribute to slow files. Certainly a 35 meg file with additional xrefs is going to be somewhat slow. You can try adding more memory to the machine and that may help.

Purge Regapps. Try to limit how many viewports are in the drawing. AutoCAD has to regenerate every viewport so the more viewports the slower it will be. If you are in 3D views, try to stick with the shademode of 2D Wireframe. I will see how this affects performance and update with results. Thanks for that. I think the -Purge Regapps did the trick! I applied that a week ago on all of my drawings, and I haven't noticed the issue at all this week.

Over time, the mode drops further and further, until all disk access is in PIO mode and the computer seems completely broken.

Deleting the controller device forces windows to reconfigure the device using the fastest mode available. A complete re-install causes this to happen. Pure speculation on my part, but it makes more sense than registry bloat when you consider that people are complaining about bitrot on machines that have gigabytes of excess RAM. Certainly additional services and other background processes contribute to slower boot times, but the idea that the performance of the software would degrade without impacting other functions is pretty unlikely.

I suspect that for many people, it's the accumulation of adware. I haven't done a scientific study, though. It would help to be bit more specific about the situation how much slower does what get, what are you doing to your machine, etc. If you install a lot of software, it's common to get a lot of registry entries.

Depending on the software, it may not get around to cleaning up its messes when you uninstall it. You've asked for concrete evidence that machines running various versions of MS-Windows OS become more sluggish over time. I have also observed this. There are various reasons as to why that may be the case. This will give you a concrete answer to everything but reason 2 as a lot of software now updates itself with the most recent copy automatically.

MS tries to fix the bugs but can't because it would break too many apps. Other programs have given up on the DLL hell and bring their own versions of the DLLs which they keep in their install directory. Then we have a lot of stuff going on in the background. The virus scanners get slower every day because they need to check for more signatures.

Junk piles up in the tmp directory, forcing the drive head to travel bigger distances. It takes longer to scan the directory. There are various patches and updates that Microsoft makes to its software that may play a role here as well as changes in hardware over time. The Windows registry, which almost every Windows application uses in one way or another can become very bloated with junk data over time.

This is especially true when installing and uninstalling many applications. Often applications don't clean up their registry entries after being uninstalled. There are applications out there which attempt to clean up the registry and you can do it by hand with regedit but proceed with caution- destroying an application's registry will ofter break the application and potentially the operating system.

This is just one area to look for performance gains though, hardware could also easily be the blame. It runs the exact same speed today, as it did 6 years ago, when I first set him up on it. Of course this avoids much of the possible pitfalls described in other answers, No new software installs, no registry, no extra startup applications. Others have given specifics, but I think that fundamentally, this is an example of the second law of thermodynamics. If you're not doing anything to speed Windows up, it will always get more disordered and therefore slower over time.

With all the machines I use regularly I've not noticed any slow-down from the day I first used them. Some applications are a little slower, but generally that's because a new version has some out with some new features. Overall there's not much of a difference. However , the machines which I get complaints about in the office tend to have a huge list of "services" and other applications running in the background.

Even when they do uninstall stuff the crapware they install tends to leave services around or small EXEs running. I rely on WinDirStat to find large and forgotten files, directories with too many files, and directories with too many directories.

That's how I found out about WebsiteCache, by the way. I really hope I someday find a way to clean up WinSxS folder does it stand for win-success, or is it what I'm thinking.

Running software with memory leaks will cause this, as less memory is available for caching. Take some good benchmarks, re-install the system as it was when you first got it, and then measure again.

I would be curious to see if the HDD or other components are partly to blame. Aside from adware, other application developers want to have their application load bootstrappers when windows starts, to reduce the perceived time it takes their application to load, or they want a background service to handle downloading updates etc. To compare, try opening up msconfig and disabling all startup items and services and then rebooting.

It's not only to do with the registry. When applications are installed, they sometimes install a load of unnecessary junk which even if the programs are unused, then run in the background from start-up.

When applications are uninstalled do they always uninstall properly, or do they leave bits of the application and files behind or leave windows still attempting to find, run or use various parts now missing, or have pieces been removed that other programs also depend on?

Install and uninstall application programs often enough and eventually Windows itself starts to become unstable and needs a clean install. It primarily has to do with disk fragmentation and an increasing number of services and background processes as additional software is installed.

Vista solves disk fragmentation issues very cleverly: So cleverly that Vista machines tend to actually increase in speed over time. On the other hand, installing lots of services can drag down Vista just like it can XP. Windows 7 also has the Vista features that prevent the OS from slowing down over time due to fragmentation. Note that "fragmentation" in this context refers not only to individual files being fragmented but also to collections of files that are loaded at the same time not being together on the disk.

The problem is that Windows does not have a repository for software, Linux have all its software organized by some dictated install software apt-get, etc. The problem is not Windows itself, but rather how the applications use the registry. In Linux each file of a program has a place to be and the dependencies are handled manually or by some master control software. In windows the person who made the application also has to make an uninstallation program. Well, you usually don't want the user to uninstall your software and if the user does that you don't usually care about what happens to the user.

I agree that Windows slowdown is a fact of life for any Windows system although I haven't used Windows Vista or Windows 7 much, so I can't comment. They take time at startup and take resources during general running. One on its own probably won't make a difference, but the build up of them over time does. It's worth taking a look at the list of services running on your machine and changing their startup options if you don't use them.

Make sure you investigate exactly what they do first though. Starting up itself can be quite a resource hogging task also. It's worth defragging the start up from time to time with a free, Microsoft supplied application, called BootVis. This will profile your machine during startup and reorder defrag anything that needs to be loaded on start up so that it loads faster, for example, drivers. Browsers also can get loaded with add-ons and toolbars over time which will also slow down your perception of the system.

I think it's worth uninstalling unused add-ins from time to time. The best result does come from a fresh install, though. It is very interesting to read that other OS's don't suffer this problem.

Step 4. Reboot your computer, and Windows will boot in safe mode this time.

Run "msconfig" again, and untick "Safe Boot" and restart your computer. Now you are done and you can check whether the SSD is still running slow or not. It is well known that an SSD drive has to clean the data that is marked for deletion before you can add new data onto it, and the cleaning process will cost much time.

Thus, the SSD speed will drop down when it is writing. The TRIM technology is introduced aiming to enable the OS to tell the SSD that data blocks are unnecessary and can be deleted, and then automatically wipe them so as to speed up data writing. To put it simply, an SSD drive will run rather slow if the Trim is not running. On the contrary, a great speed boost is possible. Follow the steps to make sure the TRIM is enabled.

Type cmd in Windows search. Once the cmd program appears, right-click it and select Run as administrator. Then, in the Command Prompt window, type this command: fsutil behavior query disabledeletenotify. Press Enter , after a short while, Command Prompt will display one of the following two messages:.

If you get the second message, you can input the command: fsutil behavior set disabledeletenotify 0, and press Enter on your keyboard to enable it. Disk Defragmentation is quite useful for hard drives with moving parts since it can bring all the parts of a file together and reduce the file system fragmentation to improve the data retrieval efficiency.

However, this should never be used on an SSD because it does not have any moving parts, so whether the files are fragmented is not important. If you run defragmentation on SSD, it will add extra wear and tear by increasing the number of writing and reading, and finally lead to the SSD slowing down and even decrease its expected lifespan.

It is wise to disable the disk defragmentation on SSD. Open "File Explorer". Right-click the SSD you need to optimize and select "Properties" from the context menu. Select the "Tools" tab, and then click the "Optimize" under the "Optimize and defragment" drive section.

Click on the "Change settings" button. A mini window will pop out, then untick the "Run on a schedule" and click "OK".

Disabling the Hibernation could free up lots of disk space on your SSD since it always takes up about the same amount of capacity as RAM installed in the computer.
