I know Windows XP is already a very old system but some still use it and since you guys can’t expect much from Microsoft to fix things, I’ve decided to make this fix sometime ago on my old blog. I’ve had massive problems with ultra slow Windows XP boot. First on friends PC, then on my netbook. After a clean system restoration, everything worked fine. After doing full Windows Update, system slowed down to a crawl on a system boot. It took forever for Security Center icon to show up and network interface to initialize. And we’re talking about 3 minutes here, not few seconds. And after 2 hour investigation, i found out the cause for this massive slowdown is, you won’t believe it, .NET Framework 4 ! The problem is apparently limited to Windows XP as i haven’t witnessed anything similar on Vista or Win7 systems and they do have .NET Framework 4 installed. Though it makes me wonder how Microsoft managed to let such crap through. And i don’t get it why .NET Framework 4 is even causing this.
Microsoft really needs to look into this problem as there is loads of ppl with this problem, it’s just that half of them don’t even know .NET Framework 4 is causing it.
Slowdown will happen if you have the following:
– Windows XP SP3
– installed .NET Framework 4
How to fix this problem:
Microsoft hasn’t provided an official fix yet, but here is the fix that solves this slow system startup.
Just download the fix tool, unpack it and run. It will probably take few minutes to process.
In case if there are any errors inside this fix tool after running it, please contact me as this version is using a fixed execution path and will probably fail to work once .NET 4 minor version changes or if you have Windows installed on drive other than C:
It will probably be required to run this fix again after installing new .NET Framework updates unless MS will include fix for this in such update… which is a bit unlikely considering the age of Windows XP…
