My computer is an HP All-in-one, and it ran quite quickly when Windows 10 was installed. Everything was great when I switched to Windows 11 for approximately three months until the computer started slowing down. I've lately discovered that it takes a long time to start up, and some programs, including Visual Studio Code, have issues operating. The Chrome app is also sluggish. Can I speed up my PC without switching to Windows 10?
The performance of your computer can deteriorate over time due to various factors, including hardware failures, insufficient storage space, malware or virus infection, and so on. According to your description, your computer is sluggish after upgrading your Windows 10 to Windows 11. You can run an antivirus software first to check for any malware or virus in your computer. If yes, seeking professional assistance to diagnose and resolve any underlying hardware or software issues is advisable.
If not, it's probably because your C drive that stores Windows systems is out of space. In this case, EaseUS Partition Master is your perfect option, and it simplifies the C drive space-extending procedure, enabling you to create additional space while preserving your existing data. This trust-worthy third-party utility offers two effective methods to address the system C drive space low problem.
Situation 1. Extend C drive with unallocated space
If you still have unallocated space on your hard drive, use the "Resize/Move" feature of EaseUS Partition Master as follows:
Step 1. Right-click on the System drive that contains Windows 11 and select "Resize/Move."
Step 2. Drag the C drive's end into the unallocated space(It's ok if the free space is not contiguous). And click "OK".
Step 3. Click "Execute Task" and "Apply" to extend the C drive's space.
Situation 2. Extend C drive without unallocated space
This method can apply when you don't have unallocated space on your system disk.
Step 1. Select "Allocate Space" from the context menu of a large partition with enough free space on your system disk.
Step 2. Choose the system drive at the "Allocate Space From (*) To" section, and drag the end of the system drive into the unallocated space. Click "OK" to ensure.
Step 3. Click "Execute Task" > "Apply" to begin the operation and extend the C drive.
