Error 501 is an error code that sometimes may occur while you are using Internet Explorer on your Windows PC. The error message is displayed as:
'Error 501: Not implemented or not supported.'
Error CausesIt is difficult to narrow down the ultimate cause of error 501. This is because this error code can be triggered by multiple reasons such as:
The occurrence of this error regardless of what the cause is may cause a lot of inconvenience to you. And if not fixed on the time it can lead to system failure too.
To repair the error 501, identifying the cause for the error really helps. By identifying the cause, you can easily select the most suitable solution to fix it.
Solution: If the above cause is the reason for error 501, this means the Local Policy Rights Settings have been altered. And because of that, Windows is not running your desired program. To solve this error simply log on to Windows as an administrator.
Then run local computer policy snap-in. Open it and click on the computer configuration. Here you will see the Windows settings option.
Click on it and then open security settings, local policies, and click on properties. Now in the add users section select the user which you want to add to the policy and save by pressing OK.
After you’ve made changes, now try using internet explorer again. If this is the cause for the error pop, the error will not occur. If it still occurs then this means there is some other underlying cause for the error. Read on to find out.
Solution: Error 501 may also occur due to improper program installation. The best way to resolve it is to uninstall recently installed programs.
Solution: Sometimes during installation registry keys also get damaged or changed. If changes in the LocalAccountTokenFilterPolicy” registry key is the issue, then you need to alter the registry key ‘LocalAccountTokenFilterPolicy settings and its value.
This key inside the registry database allows Windows to control the various access options that you have. However, due to wrong settings, it denies access and shows error 501 when you open Internet Explorer.

In such cases, if your computer is stuck in a reboot loop, you need to troubleshoot the problem via Safe Mode or in the Advanced Startup options screen.
Raptor Lake, a new and upcoming Intel 13th generation CPU will break the 6GHz barrier for the first time ever in normal working mode, overclocked mode in Intel words will go as high as 8GHz. CPU will be 15% faster than Alder lake in single-threaded tasks and a stunning 41% faster in multi-threaded workloads.
The current world record for overclocking is 8.72GHz done with AMD FX-8370 and Intel is aiming at breaking that record with Raptor Lake, of course, this kind of extreme overclocking will require some top-of-the-line nitrogen cooling systems.

Raptor Lake will run on the current LGA 1700 socket, so you will not need to buy another motherboard for CPU and they will also be manufactured on a 10nm process which means that you will need to take care of cooling and power supply if they really go over 6GHz.
Mid-range Intel Core i5-13600K processor will come with 14 cores inside and 20 threads running at a maximum P-core frequency of 5.1GHz, while Core i7-13700K will have 16 cores and 24 threads and run on 5.3GHz max P-core frequency. Best i9-13900K will come packed with 24 cores, 8 of them will be P-cores, and the rest 16 are E-cores, and 32 threads. It will reach 5.4GHz frequency but it was stated it can go to 5.8GHz with Thermal Velocity Boost.
After this statement, we can clearly see that the 6GHz breaker CPU will probably be an i9 special KS variant. In other words, specially tested and picked existing i9 running at higher speeds as was with Alder Lake as well where normal i9-12900K ran at 5.2GHz while i9-12900KS was running at 5.5GHz.

The true cause is that there is no working Border Gateway Protocol (BGP) routes into Facebook's sites. BGP is the standardized exterior gateway protocol used to exchange routing and reachability information between the internet top-level autonomous systems (AS). Most people, indeed most network administrators, never need to deal with BGP.
Cloudflare VP Dane Knecht was the first to report the underlying BGP problem. This meant, as Kevin Beaumont, former Microsoft's Head of Security Operations Centre, tweeted,
"By not having BGP announcements for your DNS name servers, DNS falls apart = nobody can find you on the internet. Same with WhatsApp btw. Facebook has basically de-platformed themselves from their own platform."
Many people are very annoyed by this and with the fact that they cannot use their social media platforms but it seems that Facebook employees are in even bigger annoyance as it was reported that Facebook employees can't enter their buildings because their "smart" badges and doors were also disabled by this network failure. If true, Facebook's people literally can't enter the building to fix things.
Reddit user u/ramenporn, who claimed to be a Facebook employee working on bringing the social network back from the dead, reported, before he deleted his account and his messages:
"DNS for FB services has been affected and this is likely a symptom of the actual issue, and that's that BGP peering with Facebook peering routers has gone down, very likely due to a configuration change that went into effect shortly before the outages happened (started roughly 1540 UTC). There are people now trying to gain access to the peering routers to implement fixes, but the people with physical access is separate from the people with knowledge of how to actually authenticate to the systems and people who know what to actually do, so there is now a logistical challenge with getting all that knowledge unified. Part of this is also due to lower staffing in data centers due to pandemic measures."
Ramenporn also stated that it wasn't an attack, but a mistaken configuration change made via a web interface.
Both BGP and DNS are down, the "connection to the outside world is down, remote access to those tools don't exist anymore, so the emergency procedure is to gain physical access to the peering routers and do all the configuration locally."
Technicians on site don't know how to do that and senior network administrators aren't on site.
It seems that it will all be down for a couple of more hours before the issue is resolved.
