What "ffffffff" in the registry show / do?

I installed and started playing a new game on a machine with proc Turion dual core and 2 GB of ram.  The game has started giving me messages "paged pool memory low" and performed very badly.  After digging around on the internet, I learned that disabling "Terminal services" in addition to change a regedit file might solve this problem.

I followed the instructions and changed 'paged pool limit', in regedit 0x10000000 to 0xffffffff.

After you restart, process Explorer showed that my limit of paged pool had jumped from 160MO to 358MB.  Now, the game runs perfectly, and the laptop seems to run faster in general.

My question is... why was that work?  What does "ffffffff" in a .reg file?

The 4 GB (FFFFFFFF) is the maximum that can be stored in this type of field in the registry. It is easier for someone to tell you to allocate the infinite maximum rather work on maximum physics. I suspect it would work also so if you have allocated a hexadecimal value of 15752A 00, which is amount of 360 000 000 in decimal format.

  • What is the best way to correct the registry errors without the use of a registry cleaner in XP?

    I am sorry to raise this issue that so many people who have asked me.  I read pages and pages of discussions on the MS forum on this subject, and without exception, all the experts said Microsoft registry cleaners are completely unnecessary and that junk in the registers has no performance impact at all.  Instead, they say, to do x, y and z.  I am running Windows XP on my desk for five years, and gradually, he got so slow it's almost unbearable.  It takes 10-15 minutes just to start, and sometimes it takes 2 minutes or more just to open a window of browser (IE8) or go to the previous page by using the arrow to the left.  Before you tell me all the things it could be, please let me say that:

    1. my PC has not always been this slow!  It is getting worse.

    2. all my Windows software is up to date.  I have automatic updates on.

    3. I have a lot of disk space, almost 75% of free space on a hard drive of 80 GB.

    4. my PC is free of viruses, spyware and Trojans.  I have McAfee antivirus running and I also sometimes run Malwarebytes and Trojan Killer, because they always find things that don't have McAfee.

    5. I defragment my hard drive on a regular basis.

    6. I regularly delete all my temporary files by using the Windows Disk Cleanup utility.

    7. I have very little, if any "Add-ons".  No toolbar Yahoo or Google (or Bing!).

    8. I removed nearly every program that I start, so that they are not running in the background.

    9. I uninstalled all the programs that I don't use.

    However, I still have a slow ever-more computer.  Sometimes, when I see ads on TV to increase the speed of my PC, I download the 'free' software, and they claim to find hundreds or thousands of "registry errors.  When I look at the newspapers, I see many entries in registry for 'Netscape' and 'Google Earth', which I uninstalled years ago, as well as entries for the videos that I downloaded, seen once, and deleted a long time ago.

    So, what's the problem?  If it's not related to my registry (which Trojan Killer says has more 6 000 entries!), what else could be?  I would appreciate greatly any advice you can give, because there are dozens of companies on their touting their registry cleaners and the uninstall (for a price) programs, and after reading reviews of the MS MVPs, I'm skeptical of their claims.  Thank you.  :)

    I can't disagree with a lot of things have already been said.

    I'm willing to accept that your machine does actually takes 10 to 15 minutes on the clock. It's completely absurd.

    Some people call your "Windows Rot" problem. Becomes just the slower windows over time. It is a collection of things that are happening in the background. Yes I believe that the register contributes. Using a registry cleaner is not a "magic" solution But it can help a little.

    The PC care program/process you described is above average.  I suggest you add CCleaner. Disk Cleanup is not bad, CCleaner is better, cleaning of other stuff which does not resemble the DC. It won't be a significant difference because disk space is not your problem, but it will help a little.

    'Play' with the registry is VERY risky. If you decide to go ahead, I would say that first make you a copy of the full image backup using a utility that can be started and run from a CD/DVD. Just in case the registry cleaner breaks of your machine.

    Registry cleaners is that they take a "best estimate" to what is no longer necessary. Sometimes they think wrong. And each vacuum cleaner will clean slightly different sets of places.  If the tool does not provide a way to back up the registry before you start cleaning, do not use it. He is not careful enough.

    If vacuuming offer 'levels' of cleaning, enjoy. Open for more aggressive cleaning, with resetting and long series of normal use between cleanings.

    You are looking for a tool which also makes registry "defragmentation". The registry is a database that get disorganized by additions and deletions. Defragmentation will be re - organize and get rid of a 'lost' space, making it the smallest file, afterwards faster to read.  It is not something you need to do frequently, but since you've never done it in 5 years, it would help, after cleaning registry.

    Another place to find CPU and RAM wasted resources is Windows Services. These are small programs that start at boot time. They run in the background and provide support services to all applications or specific applications.  Many applications services are running even though you don't really need them. You can find information on which you can set by Googling for 'Windows XP hardening'. There are a lot of sites with good information. They call it hardening because by disabling unnecessary stuff, you leave less possible openings for the "bad guys" to the attack.

    Ultimately, I think your best bet will simply bite the bullet and re - install windows and all your applications. It's the best way to restore your computer to almost any performance fees factory. (It is not exactly factory fresh because you need to add a ton of Windows updates).

    Before you re-install, do copy image 1 or more full backups. At least one must be done using a tool that will easily allow you to extract the files. You data backup files separately to make it easier to restore the reinstallation. IE, copy it to a USB key.

    Many "experts" actually expect to, and do, re - install windows every 6-12 months!  I think it's a bit exaggerated, but they swear by it.

    Once you do your re - install, create a copy of the magnified image
    Install a firewall application (before the windows updates)
    Once you do all updates of windows, create a copy of the magnified image
    After that you re-install all your apps, create another copy of the complete picture.

    In this way, in the future, you have more current points to restore your computer to. It will reduce the time you spend to get back to the current configuration.

    On a 5 year old XP machine, you have probably 512 MB - 1 GB of RAM. You might also consider taking in the shop (or DIY) and bump the RAM up to at least 2 GB or better still max out.  The current versions of the applications use much more memory than they did 5 years ago. Even XP will be since he has been seriously corrected since then.

  • Why the registry changes or the installation of security updates does not show in the session remotely from another server?

    Original title: the remote Sessions.

    When you install updates security directly on a particular server or change the registry, how is it that change is not displayed when you establish a remote session on this server to another server? My agency uses retina to analyze our servers for security flaws and he always report servers for missing patches or incorrect permissions on some registry settings. When you connect directly to the server, it ends up being false positive hits. Retina establishes remote connections to all servers in the domain to conduct its analysis. This has been an ongoing battle.
